OEX Alternator 12V 100A Mitsubishi Style MXA335

The OEX MXA335 is a new 12V alternator rated at 100A and described as Mitsubishi style, with a pad mount arrangement and an internal regulator. It is supplied as each unit and is intended for applications that match the listed mounting and electrical details.

Key physical points to check are the 6 groove pulley, 55mm pulley outside diameter, 60mm mount leg thickness, 75mm inside mounting legs, and 175mm mount centre to centre. These dimensions matter when confirming the alternator will sit correctly in the engine bay and line up with the drive belt and brackets.

OEX lists this unit under part number MXA335, pin code IR140, and as a replacement in the rotating electrical range. It weighs 5.9kg and carries a 3 year passenger / 1 year commercial warranty, so it is worth matching both the fitment details and the application before purchase.

Application and Buying Notes

Before ordering, compare the existing alternator against the supplied details: 12V, 100A, pad mount, internal regulator, and 6 groove pulley. The physical dimensions are equally important, especially the 175mm mount centre to centre, 75mm inside mounting legs, 60mm mount leg thickness, and 55mm pulley outside diameter.

This alternator is described as Mitsubishi style and suits unit make Mitsubishi, but that does not by itself make it a direct swap for every vehicle carrying a Mitsubishi-style unit. The listed applications include Ford Escape and Mazda 3 variants, so the safest approach is to verify the original part number, mounting shape, pulley alignment, and electrical connection before fitting.

The 100A rating indicates the alternator’s output capacity, which should be compared with the vehicle’s original specification. If the original unit differs in output, pulley section, regulator type, or mounting dimensions, compatibility can be affected even where the vehicle model appears in the application list.

The 3 year passenger and 1 year commercial warranty provides added reassurance, but warranty cover does not replace fitment confirmation. When in doubt, check the MXA335 part number, the IR140 pin code, and the vehicle’s existing bracket and belt arrangement before finalising the purchase.

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 MXA335 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.

For part number MXA335, the normal identification sequence is part number, electrical rating, mounting arrangement, connector or terminal style, and pulley or drive details. 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD ESCAPE, FORD ESCAPE 2004, FORD ESCAPE 2005, FORD ESCAPE 2006, MAZDA 3, MAZDA 3 2009. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

Compatibility note: Confirm fitment by matching part number MXA335, the IR140 pin code, 12V / 100A specification, pad mount style, internal regulator, and the listed pulley and mounting measurements against the vehicle’s existing alternator.
