OEX Alternator 12V 110A Mitsubishi Style MXA2077

The OEX MXA2077 is a new 12V alternator rated at 110A and supplied in Mitsubishi style, with a 6 groove pulley, internal regulator, and pad mount arrangement. It is listed as part number MXA2077 and is sold as each, which makes it suitable for a direct replacement comparison where the original unit matches those key details.

This alternator is part of the OEX rotating electrical range and carries a 3 year passenger / 1 year commercial warranty. The unit uses pin code IR203, has a pulley outside diameter of 55mm, and weighs 5.66kg, so it is important to compare these measurements with the unit being removed before ordering.

OEX describes the range as an aftermarket option backed by quality and reliability, with ISO9001 certified factories supporting engineering, testing, and quality control procedures. For buyers working from the original alternator, the most useful checks are the 12V system voltage, 110A output, Mitsubishi style configuration, and the MXA2077 part number.

Application and Buying Notes

Before ordering, compare the removed alternator against the OEX MXA2077 using the part number, 12V voltage, 110A output, Mitsubishi style case, and pad mount layout. The pulley details matter as well: this unit has a 6 groove pulley with a 55mm outside diameter and IR203 pin code, so those points should be checked against the existing setup rather than assumed.

The alternator is listed for Mitsubishi unit make, but the supplied fitment information does not verify every vehicle application in full detail here. That means the safest approach is to confirm the original alternator number, mounting style, pulley section, and any connector or bracket details before purchasing. A close physical and part number match is the best indicator for this type of rotating electrical component.

The 110A output is the key electrical rating for this unit, so it should be matched to the vehicle’s charging system requirement and the original alternator specification. If the vehicle previously used a different amperage, pulley arrangement, or regulator type, do not assume this MXA2077 will be a substitute without checking the full application.

This is a new alternator and it is sold individually. The 5.66kg weight and 10mm adjusting hole diameter are useful reference points when comparing the replacement against the original unit. Where access is tight or brackets differ, those dimensions can help confirm whether the alternator is the correct physical match before fitting starts.

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 MXA2077 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 110A Mitsubishi Style. Part number MXA2077 should be checked first. Listed voltage is 12. Listed output rating is 110. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. 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 MXA2077, 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 the MXA2077 part number, 12V system, 110A output, Mitsubishi style design, pad mount, 6 groove 55mm pulley, and IR203 pin code against the original alternator and vehicle application details before ordering.
