OEX Alternator 12V 100A Mitsubishi Style MXA2084

The OEX MXA2084 is a new 12V alternator rated at 100 amps and supplied as an each unit. It is described as Mitsubishi style, with a pad mount, 6 groove pulley, and a Field Control Unit regulator type. The unit also carries a Digital Field Report Terminal, which is an important identifying detail when comparing it with similar-looking alternators.

This alternator is listed under part number MXA2084 and is noted as not interchangeable with MXA333. OEX also advises that it is one of two identical looking alternators with different regulator functions, so matching by appearance alone is not enough. The note specifically recommends confirming by OE number before ordering.

Key measured details include a 53 mm pulley outside diameter, 50 mm mount leg thickness, 10 mm pivot hole diameter, 10 mm adjusting hole diameter, and 169 mm mount centre to centre. The unit weighs 5.6 kg and is supplied new, with warranty cover listed as 3 years for passenger use and 1 year for commercial use.

Application and Buying Notes

Before ordering, compare the part number MXA2084 with the vehicle’s existing alternator and any OE number available. OEX specifically advises confirming by OE number because this Mitsubishi style unit has a Digital Field Report Terminal and is one of two similar looking alternators with different regulator functions.

The 12V, 100A rating is the main electrical specification, but the physical details matter just as much. Check the 6 groove pulley, 53 mm pulley outside diameter, 169 mm mount centre to centre, and the 10 mm pivot and adjusting holes to make sure the replacement matches the existing bracket and belt arrangement.

The unit is supplied new and weighs 5.6 kg, so it is not a remanufactured exchange item. If you are replacing a failed alternator, it is worth checking the regulator style and terminal arrangement carefully, especially where the original unit is close in appearance to MXA333 but not interchangeable.

Warranty cover is listed differently for passenger and commercial use, at 3 years and 1 year respectively. As with any charging system component, correct identification matters more than general similarity, so use the part number, regulator type, and mounting measurements together when checking suitability.

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 MXA2084 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 2 ALTERNATORS, Part No. MXA2084, Brand OEX, Description OEX Alternator 12V 100A Mitsubishi Style - See Note, Adjusting Hole Diameter 10, Pin Code IR127, Power Rating (Amp) 100, Pulley Section 6 Groove, Suits Unit Make Mitsubishi.

OEX Alternator 12V 100A Mitsubishi Style - See Note. Part number MXA2084 should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Pad. Regulator type is Field Control Unit. 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 MXA2084, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2006, 5-T 2007, 5-T 2008, 5-T 2009, HDT VC RETRO, HDT VC RETRO 2008. 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.

Compatibility note: Confirm fitment using part number MXA2084, OE number where available, and the listed mounting and regulator details before purchase. Do not rely on visual similarity alone, as this alternator will not interchange with MXA333.
