OEX Alternator 12V 45A Mitsubishi Style MXA223

The OEX Alternator MXA223 is a new 12V, 45A unit in Mitsubishi style, supplied as an each-item rotating electrical replacement for suitable Mitsubishi applications. Key mounting details include 54mm inside mounting legs, an 8mm pivot hole diameter, an M8x1.25 adjusting hole, and a twin leg alternator mount.

This alternator uses an internal regulator and a B section pulley with an outside diameter of 82mm. It is listed with pin code IR16 and a note for a 30cc cast iron vac pump, plus adaptor wiring to suit HXK-18 plug wiring where Red = S and White/Blue = L.

For buyers comparing replacements, the part number is MXA223 and the stated suit unit make is Mitsubishi. The listed mount centre to centre measurement is 174mm, so matching the physical mounting points and electrical connection details matters just as much as matching the 12V and 45A electrical rating.

Application and Buying Notes

Before ordering, compare the part number MXA223 and the physical details on your existing unit, especially the 54mm inside mounting legs, 8mm pivot hole diameter, M8x1.25 adjusting hole, and 174mm mount centre to centre measurement. Those dimensions are the practical checkpoints that help separate a close-looking alternator from the correct replacement.

The electrical side is just as important. This alternator is a 12V, 45A unit with an internal regulator, so it needs to suit both the charging system voltage and the vehicle’s regulator arrangement. The listed pin code is IR16, and the note specifies adaptor wiring for HXK-18 plug wiring with Red = S and White/Blue = L, so connector style should be checked before purchase.

The pulley details also need attention. This unit has an 82mm outside diameter pulley with a B section belt profile, so belt alignment and belt type need to match the vehicle setup. If the existing alternator uses a different pulley diameter or belt section, the electrical rating alone will not be enough to confirm a correct swap.

The note also mentions a 30cc cast iron vac pump, which may be relevant where the original application uses that arrangement. As with any rotating electrical component, it is sensible to compare the old unit against the replacement side by side, checking the mount type, pulley, plug, and any accessory drive features before fitting.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with ISO9001 certified factory sourcing and a nationwide warranty. That gives useful background on product supply and quality controls, but the final fit decision still comes down to matching the listed dimensions, regulator type, connector details, and Mitsubishi application.

If the existing alternator has been changed previously, do not rely on appearance alone. Replacements can look similar while using different mounting leg spacing, plug styles, or pulley arrangements. Use the supplied measurements, the MXA223 part number, and the Mitsubishi application listing together to confirm suitability.

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 MXA223 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 45A Mitsubishi Style. Part number MXA223 should be checked first. Listed voltage is 12. Listed output rating is 45. 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 B. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number MXA223, 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 45 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number MXA223, the Mitsubishi application details, and the listed mounting, pulley, and connector specifications before purchase or installation.
