OEX Alternator 12V 120A Mitsubishi Style MXA2025

The OEX MXA2025 is a new 12V alternator with a 120A power rating, built in Mitsubishi style and supplied with an internal regulator. It is listed with a twin leg alternator mount, 54mm inside mounting legs, 10mm pivot hole diameter, 10mm adjusting hole diameter, and a 185mm centre-to-centre mount measurement.

This alternator uses a 6 groove pulley with a 55mm outside diameter and weighs 5.74kg. It is identified as part number MXA2025 and pin code IR70, with the note that there are two identical looking alternators that have different regulator functions, so OE number confirmation is important before ordering.

Fitment is tied to Mitsubishi applications, with listed compatibility references that include Mitsubishi ASX, Delica D5, Lancer and Outlander, as well as Citroen C4 Aircross and Peugeot 4008. Because the note specifically warns about similar-looking units, matching the OE number and checking the regulator function are the safest ways to confirm the correct replacement.

Application and Buying Notes

Before buying, check the OE number on the original alternator and compare it with MXA2025. The listing note says there are two identical looking alternators with different regulator functions, so the regulator type and OE number matter as much as the external appearance.

Measure the mounting points on the vehicle or old unit and compare them with the 54mm inside mounting legs, 10mm pivot hole diameter, 10mm adjusting hole diameter, and 185mm mount centre to centre dimension. These are practical checks that help avoid a mismatch on installation.

Confirm the pulley setup before ordering. This unit uses a 6 groove pulley with a 55mm outside diameter, so the belt type and pulley dimensions need to line up with the vehicle already fitted.

The alternator is listed for Mitsubishi-style applications and also shows compatibility references for Citroen C4 Aircross and Peugeot 4008. Even where the model name appears in the fitment references, the safest approach is still to verify the OE number, regulator function, and mounting details against the removed part.

Before supply, the safest approach is to confirm the original unit details against the listed part number, voltage, output rating, mounting arrangement, and pulley configuration. That checking process is standard practice in the parts trade because visually similar units can still differ in service-critical ways.

For workshop, fleet, and equipment applications, accurate identification of part number MXA2025 helps avoid unnecessary freight, additional labour, and vehicle or machine downtime. Where the application is not straightforward, the original unit, OEM reference, or workshop records should be used as the primary confirmation point.

Using those checkpoints helps confirm that the listed unit matches the service requirement rather than only looking similar.

For a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.
