OEX Alternator 12V 105A Mitsubishi Style MXA2104

The OEX MXA2104 is a new 12V alternator rated at 105A, supplied as a single unit with a Mitsubishi-style mounting arrangement. It uses a twin leg alternator mount, 55mm inside mounting legs, a 185mm centre-to-centre mount spacing, and 10mm pivot and adjusting hole diameters.

This alternator is fitted with an internal regulator and a 6 groove pulley with a 55mm outside diameter. It is listed with a suit for Mitsubishi applications, and the note is important: there are two identical-looking alternators with different regulator functions, so the OE number must be checked before purchase.

The unit is identified as OEX part number MXA2104, pin code IR70, and weighs 5.1kg. It carries a 3 year warranty for passenger use and 1 year for commercial use, which gives a clear service expectation when matched correctly to the vehicle application.

Application and Buying Notes

Before ordering, confirm the OE number because this alternator is one of two identical-looking units with different regulator functions. The listed internal regulator, Mitsubishi-style layout, and MXA2104 part number are the key identifiers to compare against the vehicle’s original unit.

Check the mounting and pulley details carefully: twin leg mount, 55mm inside mounting legs, 185mm centre-to-centre, 10mm pivot and adjusting holes, and a 6 groove pulley with a 55mm outside diameter. These points need to line up with the existing alternator and belt arrangement, not just the vehicle make.

The 105A output is suitable where that amperage is specified for the application, but it should not be used as the only check. Fitment can still vary by regulator function and OE number, so the safest approach is to compare the removed alternator, the vehicle details, and the part number together before fitting.

If you are replacing a Mitsubishi alternator on an ASX or another listed Mitsubishi application, confirm the pin code IR70 and the physical dimensions before purchase. The difference between similar units is often in the regulator function, so a close match is essential for a correct installation.

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 MXA2104 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.

OEX Alternator 12V 105A Mitsubishi Style - See Note. Part number MXA2104 should be checked first. Listed voltage is 12. Listed output rating is 105. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2104, 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 105 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by matching the OE number, MXA2104 part number, regulator function, mounting dimensions, and pulley specification against the existing alternator before ordering.
