OEX Alternator 12V 40A Mitsubishi Style RXA219

The OEX Alternator RXA219 is a 12V, 40A remanufactured alternator in Mitsubishi style, supplied as a twin leg unit with an internal regulator. It is identified by part number RXA219 and pin code IR15, which are the key details to check against your existing unit before ordering.

This alternator uses an A section pulley with a 74mm outside diameter, 17 shaft dimension, 49mm inside mounting legs, and 153mm centre-to-centre mount spacing. The pivot hole diameter is 8mm and the adjusting hole is M8x1.25, so the physical mounting points need to match the vehicle or machine application.

OEX positions this range as an aftermarket option backed by ISO9001 certified manufacturing processes and a warranty of 3 years for passenger use or 1 year for commercial use. For buyers replacing an existing Mitsubishi style alternator, the part number, mounting style, and electrical rating are the most important checks before fitment.

Application and Buying Notes

Before ordering, compare the part number RXA219, pin code IR15, and the physical mounting dimensions against the alternator already in the vehicle or machine. The key checks here are the twin leg mounting style, 49mm inside mounting legs, 153mm centre-to-centre mount spacing, 8mm pivot hole diameter, and M8x1.25 adjusting hole.

Electrical match matters as much as the bolt pattern. This unit is rated at 12V and 40A with an internal regulator, so it suits applications that were designed for that charging setup. If your existing alternator has a different voltage, output, or regulator arrangement, it should not be assumed to be interchangeable.

The pulley specification also needs attention because this unit has an A section pulley with a 74mm outside diameter. Belt profile and pulley size must line up with the drive system already on the vehicle or equipment, otherwise the alternator may not run correctly even if the mounting points look close.

Because the fitment list covers several Mitsubishi vehicles and equipment applications, plus Bobcat 3022 and Mercedes-Benz Sprinter 3, it is still best practice to verify the existing unit by part number and measurements. That approach is especially important on remanufactured rotating electrical parts where variations can occur between similar-looking assemblies.

If the application is commercial or used in an industrial environment, the warranty period is 1 year rather than the 3 years listed for passenger use. Confirm how the alternator will be used before you buy, and keep the invoice and part details with the installation records.

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 RXA219 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. RXA219, Brand OEX, Description OEX Alternator 12V 40A Mitsubishi Style, Adjusting Hole Diameter M8x1.25, Pin Code IR15, Power Rating (Amp) 40, Pulley Section A, Suits Unit Make Mitsubishi.

OEX Alternator 12V 40A Mitsubishi Style. Part number RXA219 should be checked first. Listed voltage is 12. Listed output rating is 40. 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 RXA219, 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 40 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include 5-T 2008, 5-T 2009, BOBCAT 3022, BOBCAT 3022 1989, BOBCAT 3022 1990, BOBCAT 3022 1991. 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: Confirm compatibility by matching part number RXA219, pin code IR15, mounting style, pulley details, and the listed electrical specifications with the unit being replaced. Do not rely on appearance alone, as similar Mitsubishi style alternators can differ in mounting and pulley configuration.
