OEX Alternator 12V 90A Mitsubishi Style MXA2032

The OEX Alternator MXA2032 is a 12V, 90A unit described as Mitsubishi style, supplied new and sold as each. It carries an internal regulator, a twin leg alternator mount, and a pulley outside diameter of 71.5mm, so the mounting and pulley details can be checked against the existing unit before purchase.

This alternator is listed with inside mounting legs of 66mm, a pivot hole diameter of 10mm, an adjusting hole diameter of M8x1.25, and a mount centre to centre measurement of 175mm. Those dimensions are the practical checks that matter when replacing a unit with similar physical layout, especially where the alternator brackets and adjustment points need to line up correctly.

The unit is identified with part no. MXA2032 and pin code IR49, and the note states it has a phase output connector with pin code IR20. An adaptor is noted to suit HXK-32 and HXK-24, which is important when matching the connector arrangement to the vehicle’s charging system wiring.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factories supporting engineering, testing and quality control procedures. The listed warranty is 3 years for passenger use and 1 year for commercial use, which gives clear context for how the unit is supported after purchase.

Application and Buying Notes

Before ordering, compare the part number MXA2032 with the existing alternator and check the physical measurements: 66mm inside mounting legs, 175mm mount centre to centre, 10mm pivot hole diameter, and M8x1.25 adjusting hole diameter. These points are the quickest way to confirm whether the replacement will sit correctly in the bracketry already on the vehicle or machine.

The pulley details also matter. This unit has a 71.5mm outside diameter pulley with an A section pulley profile, so the belt type and pulley size should be matched to the application. If the belt or pulley arrangement differs from the one already fitted, the alternator may not be suitable even if the unit appears similar at first glance.

Connector style is another key check on this alternator. The listing notes a phase output connector with pin code IR20, while the unit itself is identified with pin code IR49, and an adaptor is noted to suit HXK-32 and HXK-24. It is worth verifying the plug, connector location, and any adaptor requirement against the existing charging system before finalising the order.

The listed fitment references include Ford Courier, Mazda B-Series, and a number of TCM models. Those application references are helpful, but they should still be checked against the vehicle’s exact build and the physical alternator already fitted. Matching the application name alone is not enough if the bracket, pulley, or connector arrangement differs.

Because this alternator is new and uses an internal regulator, it is best suited to buyers replacing a similar specification unit rather than trying to adapt a different charging setup. If your current alternator uses a different mounting pattern, pulley diameter, regulator type, or connector arrangement, confirm those details carefully before purchase.

The weight is listed at 4.58kg, which can be useful when comparing against an old unit or checking shipping expectations. For a charging component like this, the most reliable buying check is still the combination of part number, mount dimensions, pulley size, and connector details rather than appearance alone.

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 MXA2032 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.
