OEX Alternator 12V 90A Mitsubishi Style MXA2027

The OEX Alternator MXA2027 is a new 12V, 90A unit with a Mitsubishi-style design, pad mount, and internal regulator. It is listed as each and carries a 3yr passenger / 1yr commercial warranty, which is useful to note when comparing replacement alternators for the same application.

Key identifying details for this unit include part number MXA2027, pin code IR99, a 6 groove pulley, and a pulley outside diameter of 49mm. The alternator is a new unit rather than remanufactured, and the mounting measurements listed include 51mm mount centres B and 169mm mount centre to centre.

This alternator sits in the rotating electrical category and is specified at 12 volts and 90 amps. For buyers matching by physical layout, the listed mount leg thickness is 72mm, the pivot hole diameter is 11mm, and the adjusting hole diameter is 13mm, so those measurements should be checked carefully against the original unit before ordering.

Fitment guidance

• No verified vehicle fitment is supplied for this alternator.
• The only confirmed style information is Mitsubishi style, so matching should be done by part number and physical measurements rather than by make alone.
• Fitment data shown in the product record is not enough to confidently list specific vehicle applications here.
• If your removed alternator matches MXA2027, IR99, the 6 groove pulley, and the listed mounting dimensions, that is the strongest starting point for comparison.

Application and Buying Notes

Before ordering, compare the part number MXA2027 with the unit you are replacing. That is the most reliable identifier here, especially because the alternator is described as Mitsubishi style rather than tied to a single vehicle model. Also check the 12V system requirement and the 90A output, as these are the core electrical specifications for this part.

Physical fit is just as important as electrical rating. This alternator is a pad mount unit with 51mm mount centres B, 169mm mount centre to centre, 72mm mount leg thickness, 11mm pivot hole diameter, and 13mm adjusting hole diameter. The pulley is 6 groove with a 49mm outside diameter, so pulley style and belt alignment should be confirmed against the original alternator before fitment.

The regulator is internal, so the charging system setup on the vehicle must suit that arrangement. Pin code IR99 is another useful check when matching connectors or wiring layout. If the old unit is damaged or missing, compare against photos, dimensions, and connector style from the vehicle before committing to purchase.

The warranty is 3 years for passenger use and 1 year for commercial use, which may help when selecting the correct replacement for the intended application. As with any alternator purchase, confirm the existing unit’s mounting points, pulley section, and electrical plug arrangement first, because those details are what separate a correct fit from a close-looking mismatch.

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 MXA2027 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 90A Mitsubishi Style. Part number MXA2027 should be checked first. Listed voltage is 12. Listed output rating is 90. 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 MXA2027, 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 90 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include FORD FIESTA, FORD FIESTA 2004, FORD FIESTA 2005, FORD FIESTA 2006. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using part number MXA2027, pin code IR99, the 12V 90A rating, pad mount layout, 6 groove pulley, and the listed mounting measurements before ordering.
