OEX Alternator 12V 130A Mitsubishi Style MXA2046

The OEX MXA2046 is a new 12V alternator with a 130A power rating, built in a Mitsubishi style configuration and supplied under the OEX brand. It uses an internal regulator, a twin leg alternator mount, and a 7 groove pulley with a 65mm outside diameter.

Key physical points to check are the 81mm inside mounting legs, 162mm centre-to-centre mount dimension, 10mm pivot hole diameter, and M8 x 1.25 adjusting hole. The adjusting hole is threaded, and the rear mounting leg is unthreaded, so those details should be matched against the original unit before ordering.

This unit is listed as part number MXA2046, pin code IR203, and weighs 6.36kg. It is identified as suitable for Mitsubishi applications, but it will not replace MXA2060, the 150 amp unit, so the amperage and mounting details need to be confirmed carefully before fitment.

Application and Buying Notes

Before purchasing, compare the original alternator against MXA2046 in the mounting area first. The 81mm inside mounting legs, 162mm mount centre-to-centre measurement, 10mm pivot hole, and M8 x 1.25 adjusting hole are the most useful checks for confirming whether this unit matches the one already fitted.

The note on this alternator is important: the adjustment hole is threaded, the rear mounting leg is unthreaded, and the adjusting hole and rear mounting leg must be confirmed against the original unit. Those details can affect whether the alternator sits and aligns correctly in the vehicle.

This alternator is a 130A unit, so it should only be considered where the original charging system specification matches that output. It will not replace MXA2060, which is the 150 amp unit, so do not use amperage alone to assume interchangeability.

The 7 groove pulley and 65mm outside diameter are also part of the fitment check. Belt type and pulley layout need to match the vehicle’s existing setup, particularly when the original alternator has a different groove count or pulley size.

Because this is a new alternator with an internal regulator, it is best suited to applications that already use that style of charging control. If the original unit differs in regulator type, mounting style, or electrical connector arrangement, the part should be checked against the removed unit before installation.

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 MXA2046 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 130A Mitsubishi Style. Part number MXA2046 should be checked first. Listed voltage is 12. Listed output rating is 130. 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 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA2046, 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.

Compatibility note: Confirm fitment using the part number MXA2046, the Mitsubishi style application, and the listed mounting and pulley measurements before ordering. Do not rely on visual similarity alone, and do not use this unit as a substitute for MXA2060.
