OEX Alternator 12V 90A Mitsubishi Style MXA230

The OEX Alternator MXA230 is a new 12V, 90A alternator in Mitsubishi style, supplied as an each unit for rotating electrical applications. It uses an internal regulator, a twin leg alternator mount, and a 4 groove pulley with a 60mm outside diameter.

Key mounting dimensions include 55mm inside mounting legs, 173mm mount centre-to-centre, an 8mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those measurements are the practical checks that matter when matching the alternator to the vehicle bracket and drive arrangement.

This unit is listed with part number MXA230 and pin code IR49. It suits Mitsubishi unit applications, and the fitment list supplied includes a range of FIAT, Hyundai, Kia, Mercedes-Benz Sprinter 5-T and Proton applications. As always, matching the part number and the physical mounting details is the safest way to confirm the correct replacement.

Application and Buying Notes

When replacing an alternator, the important checks are the part number, the regulator style, the pulley type and the mounting dimensions. For this OEX unit, the key identifiers are MXA230, 12V, 90A, internal regulator, twin leg mount, and a 4 groove pulley with a 60mm outside diameter.

The mounting measurements supplied are specific and worth comparing carefully before ordering: 55mm inside mounting legs, 173mm centre-to-centre between mounts, 8mm pivot hole diameter, and M8x1.25 adjusting hole diameter. If any of those points differ from the vehicle’s existing unit or bracket layout, the alternator may not install correctly even if the general application looks close.

Because the fitment list covers multiple makes and models, it is best to verify against the vehicle’s current alternator and not just the badge on the car. The supplied application data includes Mitsubishi-based fitment along with selected FIAT, Hyundai, Kia, Mercedes-Benz Sprinter 5-T and Proton vehicles, so confirming the exact application is essential.

For charging system work, output rating also matters. This alternator is rated at 90A, which is a useful reference when matching the electrical load expectations of the vehicle. The unit is new rather than remanufactured, and the listed warranty is 3 years for passenger use and 1 year for commercial use.

If you are replacing a failed alternator, also check the belt running surface and pulley groove count. This unit uses a 4 groove pulley, so the existing belt setup needs to match that arrangement. The weight is listed at 4.92kg, which can help when comparing against the removed part during inspection.

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 MXA230 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.

Relevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty 3yr Passenger 1yr Commercial, Inside Mounting Legs 55mm, Pivot Hole Diameter 8, Pulley Outside Diameter 60mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 173mm, Weight 4.92kg.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. MXA230, Brand OEX, Description OEX Alternator 12V 90A Mitsubishi Style, Adjusting Hole Diameter M8x1.25, Pin Code IR49, Power Rating (Amp) 90, Pulley Section 4 Groove, Suits Unit Make Mitsubishi, Alternator Mount Twin Leg.

OEX Alternator 12V 90A Mitsubishi Style. Part number MXA230 should be checked first. Listed voltage is 12. Listed output rating is 90. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA230, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using part number MXA230, the 12V 90A specification, the internal regulator, and the mounting measurements before purchase. Do not rely on the vehicle badge alone, as alternator brackets, pulley sections and regulator styles can vary between applications.
