Alternator 11377 A003TG3181 5705KA 1800A053 CA2013IR A3TG3181 JFZ1926E for Mitsubishi ASX Lance Citroen C-Crosser

Product Overview

When a 2014 Mitsubishi ASX rolls into your bay with a dead charge system, the part number on the old unit reads 1800A053. So does the one on a 2013 Peugeot 4008. And a 2012 Citroen C-Crosser. And a late-model Lancer. Four vehicles, three brands, one alternator. That is the nature of this platform.

The unit delivers 12V at 120A, uses a 6PK multi-rib pulley, and comes in a new, unmarked kraft-paper box with a 1-year manufacturer warranty. Primary OE references are 1800A053 and its sibling 1800A322. The aftermarket cross-reference landscape is wide: A3TG3181 and A003TG3181 (Mitsubishi family), CA2013IR (Cargo), LRA03488 (Lucas European), JFZ1926E, and 5705KA. Numbers that look unrelated but describe the same physical unit.

Stock is available immediately, with a 10-day lead time to ship when replenishment is needed. This is a new, not remanufactured, replacement, so there is no core charge and no waiting on a cores return cycle. The product sits cleanly in a cross-brand compact SUV segment: Mitsubishi ASX and Lancer owners on one side of the catalog, Citroen C-Crosser and Peugeot 4008 operators on the other. Both sides point to the same alternator. That is the piece worth knowing before you quote a price or build a parts program around this unit.

One Platform, Three Badges: Why This Alternator Lives in Multiple Catalogs

Between 2010 and 2016, Mitsubishi and PSA ran a joint venture that produced three compact SUVs on the same platform, with the same 2.0L four-cylinder engine, but sold under three different badges in three different markets. In Japan and Australia: Mitsubishi ASX and Lancer. In Europe: Citroen C-Crosser and Peugeot 4008. Same platform, same drivetrain, same 4B12 MIVEC engine under the hood, and the same charging system.

The alternator for this platform puts out 120A. That is not an accident. The 2.0L 4B12 engine in these vehicles consistently pairs with a CVT, which places a persistent electrical draw on the charging system through its hydraulic pump motor and electronic controller. Add MIVEC variable valve timing, power steering assistance, and the standard complement of comfort electronics on a European-market vehicle, and the charging demand climbs past what a standard 90A unit handles comfortably. The 120A output is a deliberate step up from the smaller-displacement 4B10 platform's typical 100A rating.

Compare the output across the Mitsubishi four-cylinder range to understand where this unit sits. The 4B10 1.8L in earlier Lancer applications typically runs 100A. The L200 diesel work truck, a vehicle built around minimal electrical load, ships with 90A. The Outlander V6 gets 120A. This alternator's 120A on a 2.0L four-cylinder reflects the CVT and MIVEC combination rather than raw displacement. It is the right spec for the platform it serves.

Technical Specifications

Engine Compatibility & Cross Reference

The same physical unit carries different part numbers across Mitsubishi (A3TG) and European aftermarket catalogs (LRA, CA, JFZ). All listed numbers describe the same alternator with identical mounting, pulley, and electrical specifications.

What to Look for in a Replacement

The cross-brand nature of this platform shapes every part of sourcing and fitting. Here is what actually matters when you are spec'ing, quoting, or installing this alternator.

Effective coverage spans three brands from one SKU. The ASX, the Lancer, the C-Crosser and the 4008 share a parts bin, and one alternator covers all four vehicles when the application is correct. For a distributor, that means consolidating what could be three separate stock lines into a single unit. The addressable market per SKU is wider than it first appears, because a Citroen owner and a Mitsubishi owner are both a sale for the same box.

The 120A output on a 2.0L four-cylinder is purposeful, not excessive. The CVT on this platform runs a dedicated hydraulic pump motor that draws a continuous electrical load. MIVEC variable valve timing adds a small but steady demand, and power steering assist plus the cooling fan stack on top. A 90 to 100A unit on this platform runs close to its ceiling under urban load. The 120A rating gives headroom without overspecifying the part.

The 6PK pulley matches the belt drive across all three brands. The PSA-Mitsubishi joint-venture vehicles use the same six-rib geometry as the Mitsubishi models, and the belt path drives the CVT pump, the power steering pump and the coolant pump from a single V-ribbed belt. Swapping to a 5PK or 7PK pulley creates a misfit, so the 6PK is the only correct option here. Every nameplate on this platform uses the same layout.

The same part carries three sets of numbers depending on where you look. Mitsubishi dealers quote A3TG3181. Lucas European catalogs list LRA03488. Cargo's industrial range uses CA2013IR, and JFZ lists JFZ1926E. A mechanic working on a C-Crosser might get a quote from one system, then look up the equivalent in a Mitsubishi catalog and find a completely different number. These are the same unit. Knowing the catalog mapping prevents double-ordering and pricing confusion at the counter.

Voltage quality matters on a CVT platform. The transmission control module and the hydraulic solenoid valves that manage belt clamping force are electrically sensitive. A unit producing marginal voltage under load, say 13.2V instead of the 13.8 to 14.2V the system expects, can cause shift hesitation, flare, or idle roughness that is easy to misdiagnose as a transmission fault. The 120A output is there to keep those modules supplied. With a multimeter at the battery and the engine at 2000 rpm, you want to see 13.8 to 14.2V under load.

Regional stock logic follows the catalog split. Europe sources against LRA, CA and JFZ numbers, while Japan and Australia lean on the A3TG family. Stocking by 1800A053 covers both sides, which means one box answers to a Citroen specialist in Lyon and a Mitsubishi specialist in Melbourne without a second line on the shelf. That is the inventory play this part invites.

The mass tells you about the mount. At 5.8kg net, the unit is built for a transverse layout where vibration enters from a different axis than a longitudinal pickup engine. The bracket and housing have to handle that, and an aftermarket copy has to match the original mount points to avoid premature bearing wear. Check the flange against the 4B12 bracket before fitment. It should bolt straight in with no spacers.

Application Scenarios

• European chain aftermarkets serving both Citroen C-Crosser and Peugeot 4008 from the same catalog as the Mitsubishi ASX, where one SKU clears three nameplates.

• Multi-brand independent garages that handle PSA and Mitsubishi side by side and quote the same alternator under two or three different counter numbers.

• Australian and New Zealand importers where the ASX and Lancer carry strong volume and European-sourced C-Crosser and 4008 units also filter into the parc.

• High-mileage urban commuters on the 2.0L 4B12 platform, past the factory warranty and buying on value when the charging system ages out.

• PSA-group fleet and rental operators running C-Crosser or 4008 units on high-cycle city routes with frequent restarts and heavy accessory use.

• Parts distributors consolidating cross-brand stock who replace three thin regional lines with a single 1800A053 program covering Mitsubishi, Citroen and Peugeot.

FAQ

Will the same alternator fit a Citroen C-Crosser and a Mitsubishi ASX?

Yes. The C-Crosser and the 4008 are rebadged versions of the Mitsubishi ASX and Outlander Sport platform, built on the same joint-venture underpinnings with the same 2.0L 4B12 engine and the same charging system. The 1800A053 unit fits all of them, which is why the cross-reference list spans both the A3TG Mitsubishi numbers and the LRA, CA and JFZ European catalog numbers.

Why does a Citroen or Peugeot dealer quote a different number than a Mitsubishi dealer?

Because each brand keeps its own parts catalog. Mitsubishi lists the unit as 1800A053 or A3TG3181. The European aftermarket, serving the C-Crosser and 4008, carries it as LRA03488 (Lucas), CA2013IR (Cargo) or JFZ1926E. These are the same physical alternator with identical mounting and output. The difference is catalog language, not the part. Stocking by 1800A053 covers every one of them.

Is 120A too much for a 2.0L four-cylinder?

No. The 4B12 in these vehicles pairs with a CVT whose hydraulic pump motor draws steady current, and MIVEC variable valve timing adds load on top of the comfort electronics. A 90 to 100A unit would run near its ceiling in city traffic. The 120A rating gives headroom so voltage stays above 13.8V under load. It is sized for the drivetrain, not just the cylinder count.

What are LRA03488, CA2013IR and JFZ1926E?

They are aftermarket cross-reference numbers for the same alternator. LRA03488 sits in the Lucas European catalog, CA2013IR in Cargo's industrial range, and JFZ1926E is a JFZ listing. A customer or counterman quoting any of these is asking for the 1800A053 unit. Recognising the mapping avoids ordering the same part twice under two numbers.

Does the 6PK pulley matter?

It does. The 6PK six-rib belt drives the CVT pump, power steering pump and coolant pump on this platform, and the belt path is identical across all three nameplates. A 5PK or 7PK pulley will not seat the belt correctly and the belt will slip, underdriving the accessories. Confirm the 6PK specification and check belt routing before installation.

Will this also fit the 1.8L 4B10 cars?

This unit is specified for the 2.0L 4B12 platform shared by the ASX, Lancer, C-Crosser and 4008. The 1.8L 4B10 uses a related but distinct charging specification, so confirm the original part number before fitting a 4B10 vehicle. Do not assume fitment from the engine family alone. Run the number against 1800A053 and its cross list first.

When should a high-mileage cross-brand car get the alternator replaced?

If a new battery fixes the no-start but the headlights dim at idle, the infotainment reboots at lights, or the CVT hesitates on pull-away, the alternator is the likely cause. On 4B12 cars past 150,000 km, that pattern points to the charging unit reaching the end of its output. Check voltage at the battery with the engine at 2000 rpm. Below 13.5V under load means it is time to replace.

In Practice

The hard part with this alternator is not the install. It is the lookup. A Citroen counterman, a Peugeot counterman and a Mitsubishi counterman will each hand you a different number for the same box. LRA03488, CA2013IR, A3TG3181. Three languages, one unit. Most lost sales on this part happen at the counter, when a buyer quotes a number the desk does not recognise and walks out.

The edge is knowing the map cold. When a C-Crosser owner asks for LRA03488, you answer 1800A053 and ship. When a Mitsubishi owner asks for A3TG3181, you answer the same box. One SKU, three catalogs, no second line on the shelf. The consolidation is the whole game here, because the alternative is carrying thin stock against three brands that are really one.

For the technician, the job is a 5.8kg transverse bolt-in with the 6PK pulley already fitted. Confirm the belt routing, check voltage at 2000 rpm, and the car leaves with stable shifts and bright lights at the stop light. For the parts desk, a new unit with a 12-month warranty means the call does not come back asking why the CVT is hesitating. In a cross-brand market, that quiet reliability is what keeps all three nameplates coming through your door.
