OEX Alternator 12V 150A Mitsubishi Style MXA2028

The OEX Alternator MXA2028 is a new 12V, 150A unit in Mitsubishi style, supplied as each. It uses an internal regulator, a 6 groove pulley, and is listed with a single leg alternator mount, so it is important to compare the mounting and pulley details against the unit being replaced before ordering.

Key identification numbers on this alternator are Part No. MXA2028, OEM Number 0123510004, and Pin Code IR165. The listed dimensions include a 56mm mount leg thickness, 156mm mount centre-to-centre, 10mm pivot hole diameter, 10mm adjusting hole diameter, and a 49mm pulley outside diameter.

OEX positions this alternator range around quality and reliability at aftermarket price points, with factories that are ISO9001 certified. The unit is backed by a 3 year passenger / 1 year commercial warranty, which is useful to note when comparing replacement options for a Mitsubishi application.

Application and Buying Notes

This alternator is identified as Mitsubishi style and suits Mitsubishi applications, but the critical buying check is matching the physical mounting and electrical layout. The listed 12V, 150A output, internal regulator, single leg mount, and 6 groove pulley should all be compared with the removed unit before the part is ordered or fitted.

The mounting measurements matter just as much as the electrical rating. With a 56mm mount leg thickness, 156mm mount centre-to-centre, and 10mm pivot and adjusting holes, this alternator should only be selected when those dimensions line up with the vehicle’s existing arrangement. A mismatch in these areas can stop the alternator from fitting correctly even if the plug or brand appears similar.

The OEM Number 0123510004 and Part No. MXA2028 are the best identifiers to use when checking against an existing part or parts catalogue listing. If the vehicle has been modified, fitted with a replacement engine, or previously repaired with a non-standard alternator, measure the old unit rather than assuming the catalogued application will match.

At 7kg, this is a substantial rotating electrical component, so handling and installation should be done carefully. As with any alternator replacement, confirm the belt alignment, pulley section, and mounting points before tightening the unit down, because the listed 49mm pulley outside diameter and 6 groove section need to suit the rest of the charging drive setup.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. That is useful context, but it does not replace the need to confirm the application details. Correct fitment depends on matching the part number, OEM number, voltage, amperage, regulator type, and mounting dimensions to the vehicle already in service.

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 MXA2028 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 150A Mitsubishi Style. Part number MXA2028 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 MXA2028, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Please confirm fitment by checking Part No. MXA2028, OEM Number 0123510004, the Mitsubishi style mounting arrangement, and the listed dimensions and pulley details against the existing alternator before ordering.
