OEX Alternator 12V 100A Mitsubishi Style MXA2064

The OEX MXA2064 is a new 12V alternator rated at 100A and supplied in Mitsubishi style configuration. It is listed as a quad leg alternator mount with an internal regulator, 6 groove pulley, and 51mm pulley outside diameter, so the mounting style and drive setup should be checked carefully before ordering.

This unit suits vehicles without brake energy recovery and without start-stop function. The note also directs buyers to confirm by OE number, which is important here because vehicles with brake energy recovery require MXA2087 instead. That makes application checking just as important as the 12V, 100A rating.

The alternator is identified as part number MXA2064 and carries OEX branding. It is supplied as each unit, weighs 6.4kg, and has a centre-to-centre mount measurement of 133mm, with M10x1.25 / 10 adjusting and pivot hole diameters.

Warranty cover is listed as 3 years for passenger use and 1 year for commercial use. If the existing alternator has the same part number, mounting pattern, pulley layout, and electrical configuration, that gives you a strong starting point for comparison before purchase.

Application and Buying Notes

Before fitting an alternator, compare the part number MXA2064 with the original unit and check the OE number as requested in the product note. The key application restriction here is clear: this 12V 100A Mitsubishi style alternator suits vehicles without brake energy recovery and without start-stop function.

The physical details matter as much as the electrical rating. This unit has a 6 groove pulley with a 51mm outside diameter, a quad leg mount, and 133mm centre-to-centre mounting. If those details do not line up with the original alternator, the part should be treated as unconfirmed until verified against the vehicle and OE number.

The hole sizes are listed as M10x1.25 / 10 for both adjusting and pivot points. That is useful when comparing brackets and mounting hardware, especially where previous repairs, alternator swaps, or non-original components may have altered the installation. Taking a careful comparison before purchase is the safest approach.

This alternator is a new OEX unit and weighs 6.4kg. The warranty is listed as 3 years for passenger use and 1 year for commercial use. If the vehicle is fitted with brake energy recovery, this is not the correct choice and MXA2087 is specified instead.

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 MXA2064 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 100A Mitsubishi Style - See Note. Part number MXA2064 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 Quad Leg. 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 MXA2064, 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 MAZDA 2, MAZDA 2 2014, MAZDA 2 2015, MAZDA 2 2016. 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: Please confirm fitment using the part number MXA2064, the OE number, and the application notes for brake energy recovery and start-stop function before ordering. If the vehicle has brake energy recovery, use MXA2087 instead.
