Mitsubishi Alternator 12V 130A A2TX1279AMA

This Mitsubishi alternator is a new 12V unit rated at 130A, supplied as each, with part number A2TX1279AMA. It uses an internal regulator and is noted as a twin leg alternator mount, so matching the mounting layout is just as important as matching the electrical rating.

Key physical details include a 73mm pulley outside diameter, AA pulley section, 55mm inside mounting legs, 12mm pivot hole diameter, M8 x 1.25 adjusting hole diameter, and 175mm mount centre to centre. These measurements are the practical checkpoints to compare against the original unit before ordering.

The unit is listed for Mitsubishi applications, with fitment references shown for Mitsubishi Pajero and Mitsubishi Triton in the supplied application data. Because regulator functions can differ, confirming by OE number is specifically recommended for this alternator.

Application and Buying Notes

Before buying, compare the part number A2TX1279AMA, the 12V 130A rating, and the internal regulator setup against the original alternator. The supplier note specifically advises confirming by OE number because regulator functions can differ, even where the alternator looks similar externally.

Mounting dimensions matter here. Check the twin leg mount, 55mm inside mounting legs, 12mm pivot hole, M8 x 1.25 adjusting hole, and 175mm mount centre to centre against the existing unit. A mismatch in any of these points can stop the alternator fitting correctly, even if the vehicle is one of the listed Mitsubishi applications.

The pulley details are also important. This unit has a 73mm pulley outside diameter and AA pulley section, so the belt profile and pulley size should be checked during replacement. That is especially relevant when the vehicle has had prior repairs or the charging system has been changed before.

Weight is listed at 5.8kg, which can help with handling and comparison, but the most reliable buying check is still the OE number and mounting layout. If the original alternator has a different regulator arrangement or pulley configuration, the visible fit may not be enough to confirm suitability.

For workshop and retail buyers, the safest approach is to match the alternator by OE number first, then confirm the physical mount measurements and application details. That keeps the order aligned with the supplied information and reduces the risk of ordering the wrong charging unit for a Mitsubishi application.

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 A2TX1279AMA 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. A2TX1279AMA, Brand MITSUBISHI, Description Mitsubishi Alternator 12V 130A - See Note, Adjusting Hole Diameter M8 x 1.25, Pin Code IR70, Power Rating (Amp) 130, Pulley Section AA, Suits Unit Make Mitsubishi.

Mitsubishi Alternator 12V 130A - See Note. Part number A2TX1279AMA should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is AA. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number A2TX1279AMA, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MITSUBISHI PAJERO, MITSUBISHI PAJERO 2009, MITSUBISHI PAJERO 2010, MITSUBISHI PAJERO 2011. 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 2 Years 400,000km. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using the OE number A2TX1279AMA and the mounting, pulley, and regulator details before purchase. The supplied information also notes that different regulator functions may apply, so vehicle match alone should not be used as the only check.
