Application and Buying Notes

Before ordering, confirm the replacement alternator matches the original part number MXA2101 or OEM number A3TG2881-PO, along with the Mitsubishi-style application. The key physical points to compare are the twin leg mount, internal regulator, 6 groove pulley, and the listed hole sizes of M10 and 10.5 mm.

The 80 amp rating and 12V specification need to suit the vehicle’s charging system requirements. If the vehicle originally used a different output or regulator arrangement, the alternator may not be a direct swap even if it looks similar externally.

The 55 mm pulley outside diameter and 6 groove belt section are especially important where belt alignment and drive compatibility matter. Check the original pulley section, belt type, and mounting layout before fitting, as alternators can vary within the same vehicle family.

OEX positions this alternator as a new aftermarket replacement with factory quality controls and a warranty of 3 years for passenger use or 1 year for commercial use. That warranty period is useful, but the correct part still depends on matching the application details, not the brand name alone.

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 MXA2101 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.
