OEX Alternator 12V 90A Mitsubishi Style MXA9601

The OEX Alternator MXA9601 is a 12V, 90A unit in Mitsubishi style with a 6 groove pulley and internal regulator. It is listed as a new alternator, supplied each, with a twin leg alternator mount and a 67mm pulley outside diameter.

Key physical details for checking against the original unit include 57mm inside mounting legs, 8mm pivot hole diameter, M8 adjusting hole diameter, and 173mm mount centre to centre. These measurements matter when matching the bracket layout and mounting points on the application.

OEX identifies this part as part number MXA9601, with pin code IR49 and a stated suit for Mitsubishi units. The unit weighs 5.2kg and is covered by a 3 year passenger / 1 year commercial warranty.

For buyers replacing a worn charging unit, the important checks are voltage, amperage, pulley section, regulator type, and mounting dimensions. This alternator is specified as 12V and 90A, so it is intended to match those electrical requirements rather than being a generic fitment.

Application and Buying Notes

Before ordering, compare the part number MXA9601 and the pin code IR49 with the removed unit. Those identifiers are the clearest check when you are replacing a Mitsubishi style alternator and want to avoid a mismatch in housing or connector details.

The electrical specification is 12V at 90A, so it should be matched to the vehicle or machine’s original charging setup. A unit with a different voltage or output rating may not be suitable even if the mounting points appear close.

Mounting dimensions should be checked carefully: 57mm inside mounting legs, 173mm mount centre to centre, 8mm pivot hole diameter, and M8 adjusting hole diameter. The alternator also uses a twin leg mount, so bracket style is just as important as output rating.

Pulley details also need to line up. This unit uses a 6 groove pulley with a 67mm outside diameter, so belt type and pulley diameter should be compared with the existing alternator before purchase.

If you are matching by application, use the Mitsubishi style description together with the measured dimensions and part number. That approach is more reliable than relying on appearance alone, especially when alternators have been changed previously.

The unit weighs 5.2kg and is sold as new, not remanufactured. That may matter when comparing against an existing part, particularly where physical condition or prior repairs have altered the original casing or mounting surfaces.

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 MXA9601 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.
