OEX Alternator 12V 75A Mitsubishi Style MXA233

The OEX MXA233 is a new 12V alternator rated at 75A, built in Mitsubishi style and supplied as a twin leg mount unit. It uses an internal regulator, a 4 groove pulley, and has a pulley outside diameter of 69mm, so it suits applications where those physical details match the original alternator.

This alternator is listed with a part number of MXA233 and a pin code of IR49. Mounting dimensions include 55mm inside mounting legs, an 8mm pivot hole diameter, M8 x 1.25 adjusting hole diameter, and 175mm mount centre to centre. Those measurements matter as much as the make and model application when confirming a replacement.

The unit is described as genuine Mando, with an adaptor to suit HXK-32 and HXK-24 noted. It weighs 4.9kg and is covered by a 3 year passenger / 1 year commercial warranty, which gives a clear indication of the intended use and warranty split for different vehicle types.

Application and Buying Notes

Before ordering, compare the alternator mounting and drive details against your original unit. The key checks here are the twin leg mount, 55mm inside mounting legs, 8mm pivot hole, M8 x 1.25 adjusting hole, 175mm mount centre to centre, and the 4 groove pulley with a 69mm outside diameter. If any of those dimensions differ, the unit may not interchange even if the vehicle make appears similar.

The listed application coverage includes Mitsubishi, Hyundai Excel, Hyundai S Coupe, Hyundai Sonata, Proton Persona, Proton Satria, Mitsubishi Colt, Mitsubishi Industrial, and Mitsubishi Industrial Forklifts. That is useful guidance, but the safest match is always the physical alternator and part number. Mitsubishi style alone is not enough to confirm fitment without checking the mounting layout and pulley configuration.

This is a 12V, 75A unit with an internal regulator, so it should only be considered where the charging system originally uses those specifications. The part is supplied new and identified as genuine Mando, with an adaptor to suit HXK-32 and HXK-24 noted. If your existing alternator uses a different regulator style, shaft size, or belt arrangement, stop and verify before purchasing.

Warranty coverage is stated as 3 years for passenger use and 1 year for commercial use. That distinction is important if the alternator is going into a private vehicle versus a work application, especially for Mitsubishi industrial or forklift use where duty cycle and operating conditions can differ significantly.

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 MXA233 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 MXA233, 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 75 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI EXCEL, HYUNDAI EXCEL 1990, HYUNDAI EXCEL 1991, HYUNDAI EXCEL 1992, MITSUBISHI COLT, MITSUBISHI COLT 2004. 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 the part number MXA233, the Mitsubishi style mounting layout, and the listed dimensions and pulley details against your original alternator before purchase.
