OEX Alternator 12V 110A Mitsubishi Style MXA2039

The OEX Alternator MXA2039 is a new 12V, 110A unit in Mitsubishi style, supplied as an each item for rotating electrical applications. It uses a twin leg alternator mount, with 81mm inside mounting legs and 158mm mount centre to centre, so the physical mounting points need to be checked against the original unit before purchase.

This alternator is fitted with an internal regulator and a 6 groove pulley, with a 60mm pulley outside diameter. The adjusting hole is M8x1.25, and the unit carries pin code IR49. Those details are important when matching the alternator to the vehicle’s belt drive, bracket arrangement, and wiring connection.

OEX states its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with production from ISO9001 certified factories. For this part number, the warranty is listed as 3yr Passenger 1yr Commercial, which is a useful reference when comparing replacement options for a Mitsubishi style alternator in the 110A range.

Application and Buying Notes

Before ordering, compare the part number MXA2039 and the physical details against the unit being replaced. The key matching points here are the 12V system, 110A output, twin leg mount, 81mm inside mounting legs, 158mm mount centre to centre, and the M8x1.25 adjusting hole. If any of those differ, the alternator may not suit the application without modification.

The pulley specification also matters. This alternator uses a 6 groove pulley with a 60mm outside diameter, so the belt type and pulley dimensions should be checked carefully against the existing setup. A mismatch in groove count or pulley diameter can prevent correct belt alignment and operation, even if the unit otherwise looks similar.

Because this alternator is described as Mitsubishi style and suits unit make Mitsubishi, the safest approach is to confirm the replacement by original part matching, mounting style, and electrical connection details. The pin code is IR49 and the regulator type is internal, so those items should also be compared with the removed alternator before finalising the order.

The listed warranty is 3yr Passenger 1yr Commercial, which may help when assessing the replacement for private or commercial use. Warranty does not replace fitment checking, so the vehicle application, mounting arrangement, pulley setup, and connector details should still be confirmed 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 MXA2039 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.

For part number MXA2039, 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 110 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number MXA2039, Mitsubishi style application details, twin leg mounting, 12V 110A specification, internal regulator, IR49 pin code, and the pulley and mounting measurements before buying.
