OEX Alternator 12V 90A Mitsubishi Style MXA220

The OEX Alternator MXA220 is a new 12V, 90A rotating electrical unit described as Mitsubishi style and suited to Mitsubishi applications. It uses an internal regulator, a pad mount, and a 6 groove pulley, so the mounting and drive setup need to match the vehicle before purchase.

Key dimensions listed for this alternator include a 49mm pulley outside diameter, 181mm mount centre to centre, 135mm mount centres B, 75mm mount leg thickness, and a pivot hole diameter of 9 / 10. Those dimensions matter when checking whether the alternator will physically suit the existing bracket arrangement.

OEX lists this unit at 5.9kg and backs it with a 3yr passenger / 1yr commercial warranty. The part number is MXA220, which is the safest identifier to confirm against the existing alternator and vehicle application details before ordering.

Application and Buying Notes

Before ordering, match the part number MXA220, the 12V system voltage, and the 90A output with the existing alternator details. The mounting style is pad mount, the regulator is internal, and the pulley is a 6 groove design with a 49mm outside diameter, so these points should line up with the vehicle’s current setup.

The listed measurements are important for physical fitment. Check the 181mm mount centre to centre, 135mm mount centres B, 75mm mount leg thickness, and 9 / 10 pivot hole diameter against the removed unit or vehicle mounting points. If any of these differ, the alternator may not install correctly even if the electrical rating appears similar.

This unit is described as Mitsubishi style and suited to Mitsubishi, while the supplied application information also includes Mazda entries. Do not rely on style alone; confirm the vehicle application, the mounting arrangement, and the pulley configuration before purchasing. The weight is listed at 5.9kg, which can also be useful when comparing with the existing unit.

For commercial use, note the warranty is listed as 1 year, while passenger use is listed as 3 years. If you are replacing a failed alternator, it is worth checking belt condition, pulley alignment, and charging system wiring at the same time so the replacement can be assessed properly once installed.

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 MXA220 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.
