OEX Alternator 12V 120A Mitsubishi Style MXA2029

The OEX Alternator MXA2029 is a 12V, 120A new alternator in Mitsubishi style, supplied as each unit and identified with pin code IR49. It uses an internal regulator and a 5 groove pulley, so the electrical and belt drive details need to match the vehicle application before installation.

Mounting dimensions are important with this unit. It has twin leg alternator mounting, 50mm inside mounting legs, an M10x1.25 / 10.5 pivot hole diameter, an 11mm adjusting hole diameter, and 163mm mount centre to centre. Those figures are the practical checks that help confirm whether the alternator will sit correctly on the bracketry.

The listed note also matters: the unit has a 2 pin regulator plug, with only the Warning Lamp terminal used, and an adaptor to suit HXK-32 and HXK-24 is noted. It may require external sense, so the plug arrangement and charging circuit setup should be checked carefully before purchase or installation.

Application and Buying Notes

When comparing this alternator to the unit being replaced, the most useful checks are the part number MXA2029, the Mitsubishi style housing, the 12V electrical system, and the 120A output rating. A unit can look similar and still differ in pulley section, mounting spacing, or regulator plug arrangement, so those details should be matched before ordering.

The mounting measurements are especially important on this alternator. Confirm the twin leg mount, 50mm inside mounting legs, 163mm mount centre to centre, M10x1.25 / 10.5 pivot hole diameter, and 11mm adjusting hole diameter against the original unit or the vehicle’s bracket setup. If any of those points differ, fitment may not be correct even if the alternator family appears similar.

Electrical connection is another key checkpoint. This unit is listed with a 2 pin regulator plug where only the Warning Lamp terminal is used, and an adaptor to suit HXK-32 and HXK-24 is noted. It may require external sense, so the charging circuit and plug style should be reviewed by someone familiar with the vehicle’s wiring before installation.

The 57mm pulley outside diameter and 5 groove pulley section must also be checked against the existing belt arrangement. Belt alignment and groove count need to match the vehicle setup to avoid noise, belt wear, or charging issues. The listed 5.82kg weight can also be useful when comparing against the removed unit to confirm you are looking at the same style of alternator.

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 MXA2029 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.

For part number MXA2029, 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 120 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HYUNDAI ACCENT, HYUNDAI ACCENT 2010, HYUNDAI ACCENT 2011, HYUNDAI ACCENT 2012, KIA SOUL, KIA SOUL 2009. 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 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm fitment using the part number MXA2029, the Mitsubishi style application, the 12V 120A rating, and the listed mounting and plug details before purchase or installation. If the original alternator differs in pulley section, regulator plug, or bracket dimensions, do not assume interchangeability.
