OEX Alternator 12V 150A Mitsubishi Style MXA2087

The OEX MXA2087 is a new 12V alternator rated at 150A and built in a Mitsubishi style configuration. It uses an internal regulator, a quad leg alternator mount, and a 6 groove pulley with a 56mm outside diameter, so the physical setup and electrical specification need to be checked carefully before ordering.

This alternator is suited only to vehicles with brake energy recovery. The product information also advises confirming application by OE number, which is especially important here because MXA2087 will not interchange with MXA2113 or MXA2064 due to a different regulator pin code.

As a rotating electrical component, fitment needs to be matched on more than just voltage and amperage. The listed measurements include 65mm inside mounting legs, 10.5mm pivot hole diameter, and 10.5mm adjusting hole diameter, which are useful checkpoints when comparing the unit to the existing alternator.

OEX lists this unit as part number MXA2087, with pin code IR219, and backs it with a 3 year passenger / 1 year commercial warranty. Those identifiers matter when you are matching the replacement to the vehicle and the charge system already fitted.

Application and Buying Notes

Before ordering, compare the part number MXA2087 with the existing unit and confirm the OE number where possible. This alternator is specified as 12V, 150A, Mitsubishi style, and it is only for vehicles with brake energy recovery, so the charging system type matters as much as the physical shape.

Check the mounting details against the removed alternator. The key measurements supplied are 65mm inside mounting legs, 10.5mm pivot hole diameter, 10.5mm adjusting hole diameter, and a 56mm outside pulley diameter with 6 grooves. If any of those points differ, the unit may not suit the application even if the vehicle is similar.

The regulator pin code is IR219, and the product note specifically says it will not interchange with MXA2113 or MXA2064 because the regulator pin code is different. That is an important check for Mitsubishi style alternators, where visually similar units can still be incompatible at the plug or regulator level.

This alternator is new and covered by a 3 year passenger / 1 year commercial warranty. Warranty terms are useful, but they do not replace proper identification. Matching the part number, OE number, mount type, pulley type, and brake energy recovery requirement is the safest way to buy the correct replacement.

If you are working from a vehicle registration or model reference, use it only as a starting point. The product data supplied here does not verify individual model-by-model fitment, so the safest approach is to compare the removed alternator and the OE number before fitting.

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 MXA2087 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 -Suits Vehicles With Brake Energy Recovery - See Note. Part number MXA2087 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 Quad 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 MXA2087, 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: Confirm compatibility using part number MXA2087, the OE number on the removed unit, and the listed application details before ordering. This alternator is only suited to vehicles with brake energy recovery and does not interchange with MXA2113 or MXA2064.
