Application and Buying Notes

Before ordering, compare the RXA270 part number, 12V rating, and 70A output with the alternator already fitted to the vehicle. The physical details matter just as much as the electrical ones: 66mm inside mounting legs, 175mm mount centre-to-centre, and a twin leg mount are the main checks that help confirm you are looking at the same style of unit.

The pulley also needs to match. This alternator uses a 73mm outside diameter pulley with an A-section belt profile, so belt type and pulley size should be confirmed against the existing unit. If the belt profile or pulley diameter differs, the alternator may not suit the application even if the plug or general shape looks similar.

This unit is listed as Mitsubishi style and suits unit make Mitsubishi, but that alone is not enough to confirm vehicle fitment. Alternators can vary by mounting layout, connector style, regulator type, and pulley setup, so it is worth checking the mounting dimensions, pin code IR15, and your original part number before purchase.

The warranty is 3 years for passenger use and 1 year for commercial use, which is a useful commercial comparison point when choosing a replacement alternator. As with any remanufactured electrical component, correct identification of the existing unit is the best way to avoid a return and to make sure the replacement matches the vehicle’s charging system requirements.

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 RXA270 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 70A Mitsubishi Style. Part number RXA270 should be checked first. Listed voltage is 12. Listed output rating is 70. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number RXA270, 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 70 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching the RXA270 part number, the 12V 70A specification, and the mounting and pulley dimensions against your original alternator. If there is any mismatch in mounting, pulley type, or connector details, check the application before buying.
