OEX Alternator 12V 120A Mitsubishi Style MXA2023

The OEX Alternator MXA2023 is a 12V, 120A rotating electrical unit in Mitsubishi style configuration, supplied new as an each item for applications that suit a Mitsubishi unit make. It uses an external regulator, a twin leg alternator mount, and a 4 groove pulley section, so those details need to line up with the original unit before purchase.

Key mounting and sizing details include 54mm inside mounting legs, a 172mm mount centre to centre measurement, a 10mm pivot hole diameter, and an 11mm adjusting hole diameter. The pulley outside diameter is 67mm, and the unit weighs 6.36kg, which gives a practical reference when comparing against the original alternator in hand.

This alternator is identified as OEX part number MXA2023 and pin code ER50. OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with factories that are ISO9001 certified to support engineering, testing, and quality control procedures. Warranty cover is listed as 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, compare the part number MXA2023 and the physical details on the vehicle’s original alternator. The critical checks here are the 12V system, 120A output, external regulator, twin leg mount, 54mm inside mounting legs, and the 4 groove pulley section. If any of those differ from the removed unit, it may not be the correct match.

Mounting measurements matter just as much as electrical output. This unit has a 172mm mount centre to centre, a 10mm pivot hole, and an 11mm adjusting hole, so the brackets and adjuster must suit those dimensions. The 67mm pulley outside diameter and 6.36kg weight are also useful cross-checks when confirming the replacement against the original alternator.

The listed application data includes Chrysler Neon and Chrysler PT Cruiser model entries, but alternator fitment can still vary by engine, charging system, bracket style, pulley configuration, and production date. Use the vehicle details together with the part number and the removed unit’s measurements rather than relying on model name alone.

If you are working on a commercial vehicle, note the warranty difference: 1 year commercial versus 3 years passenger. That makes it worth confirming the vehicle use, the charging system arrangement, and the alternator mounting points before fitting, because once the wrong unit is installed the time and labour involved can be significant.

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 MXA2023 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. MXA2023, Brand OEX, Description OEX Alternator 12V 120A Mitsubishi Style, Adjusting Hole Diameter 11, Pin Code ER50, Power Rating (Amp) 120, Pulley Section 4 Groove, Suits Unit Make Mitsubishi, Alternator Mount Twin Leg.

OEX Alternator 12V 120A Mitsubishi Style. Part number MXA2023 should be checked first. Listed voltage is 12. Listed output rating is 120. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is External. 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 MXA2023, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CHRYSLER NEON, CHRYSLER NEON 1999, CHRYSLER NEON 2000, CHRYSLER NEON 2001. 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 with the part number MXA2023, the 12V 120A specification, external regulator type, twin leg mount, 54mm inside mounting legs, and the vehicle application details before purchase. Do not rely on model name alone; compare the removed alternator and mounting measurements to the listed specifications.
