OEX Alternator 12V 90A Mitsubishi Style MXA2073

The OEX Alternator MXA2073 is a new 12V, 90A rotating electrical unit built in Mitsubishi style for applications that suit a Mitsubishi alternator. It uses an internal regulator, a 6 groove pulley, and a twin leg alternator mount, so the physical layout needs to match the vehicle before purchase.

This unit is listed with an inside mounting legs measurement of 66mm, a mount centre to centre measurement of 175mm, a pivot hole diameter of 10mm, and an adjusting hole threaded M8 x 1.25. Those measurements matter because alternator fitment is determined by both electrical specification and bracket geometry.

At 4.84kg, with a pulley outside diameter of 64mm and a 90 amp power rating, this alternator is suited to buyers looking for a direct replacement in the correct Mitsubishi-style application rather than a universal fit part. The part number is MXA2073, which is the safest reference to confirm before ordering.

Application and Buying Notes

Before ordering, compare the part number MXA2073 with the alternator already fitted to the vehicle, then check the Mitsubishi-style mounting layout against the 66mm inside mounting legs and 175mm mount centre to centre dimensions. Alternators can look similar from the outside while differing in bracket spacing, pulley specification, or regulator type.

This alternator uses an internal regulator and a 6 groove pulley with a 64mm outside diameter. Those details need to suit the vehicle’s charging system and belt arrangement. If the current alternator uses a different pulley section, different mounting ears, or a different regulator arrangement, the part may not be an exact match even if the vehicle is Mitsubishi.

The listed fitment references include Mitsubishi Challenger, Mitsubishi Lancer, and Mitsubishi Triton, but those references should still be checked against the specific vehicle and existing unit. Year ranges and model variants can change alternator brackets and electrical requirements, so confirm the installed part number, connector arrangement, and physical measurements before finalising the order.

This is a new OEX alternator, not a remanufactured unit, and it carries a 3yr Passenger / 1yr Commercial warranty. Warranty terms do not replace fitment checks, so the safest approach is to match MXA2073, confirm the 12V and 90A specification, and verify the twin leg mount and M8 x 1.25 adjusting hole before purchase.

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 MXA2073 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. MXA2073, Brand OEX, Description OEX Alternator 12V 90A Mitsubishi Style, Adjusting Hole Diameter M8x1.25, Pin Code IR49, Power Rating (Amp) 90, Pulley Section 6 Groove, Suits Unit Make Mitsubishi, Alternator Mount Twin Leg.

OEX Alternator 12V 90A Mitsubishi Style. Part number MXA2073 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 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2073, 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.

Available application references include MITSUBISHI CHALLENGER, MITSUBISHI CHALLENGER 2008, MITSUBISHI CHALLENGER 2009, MITSUBISHI CHALLENGER 2010. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number MXA2073, the Mitsubishi-style twin leg mounting pattern, the 12V 90A specification, and the listed pulley and hole measurements before ordering.
