Genuine Products Alternator 12V 140A Mitsubishi Style MXA330

The Genuine Products MXA330 is a new 12V alternator rated at 140A, built in Mitsubishi style and supplied as a single-leg mount unit. It is listed with an internal regulator, a 6 groove pulley, and a 57mm pulley outside diameter, which are the key details to match against the vehicle setup before ordering.

Mounting measurements matter on alternators, and this unit is specified with a 51mm mount leg thickness, 10mm pivot hole diameter, 10mm adjusting hole diameter, and 139mm mount centre-to-centre. Those figures should be checked carefully against the existing unit or the vehicle application to avoid a mismatch at installation.

This alternator carries part number MXA330 and pin code IR193, and it is noted for Mitsubishi unit make applications. A further note advises that the field report terminal has a different output parameter to MXA332 and MXA2020 and will not interchange, so the part number and terminal details need to be confirmed before purchase.

Application and Buying Notes

Before ordering, confirm the alternator in the vehicle matches the mounting layout and measurements listed here: single-leg mount, 51mm mount leg thickness, 10mm pivot hole, 10mm adjusting hole, and 139mm centre-to-centre. These dimensions are often just as important as the 12V, 140A electrical rating when fitting a replacement alternator.

The pulley details also need to match. This unit is specified with a 6 groove pulley and a 57mm outside diameter, so the belt arrangement on the vehicle should be checked against the existing alternator rather than assumed from the model name alone.

The supplied note states that the field report terminal has a different output parameter to MXA332 and MXA2020 and will not interchange. That makes part number checking essential, especially where multiple alternator variants may appear similar from the outside.

If you are comparing against a removed alternator, match the part number MXA330, pin code IR193, and the listed mounting and pulley details together. Using only one of those identifiers is not enough when there is a note about non-interchangeable terminal output parameters.

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 MXA330 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 MXA330, 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 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using the part number MXA330, the IR193 pin code, and the listed mount and pulley measurements before purchase. If the existing unit is MXA332 or MXA2020, the terminal/output parameter note indicates it will not interchange.
