OEX Alternator 12V 100A Delphi Style DXA605

The OEX Alternator DXA605 is a new 12V, 100A alternator in a Delphi style configuration, supplied with an internal regulator and a 6 groove pulley. It is intended for applications that match the listed mounting dimensions, including 55mm inside mounting legs, M10x1.25 pivot and adjusting holes, and 159mm mounting centre to centre.

This unit is a quad leg alternator with clockwise rotation and a 54mm pulley outside diameter. At 5.4kg, it is a complete rotating electrical component rather than a remanufactured unit, so correct physical match-up matters before ordering or fitting.

OEX lists this alternator under part number DXA605 and pin code IR127. The warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear service benchmark for buyers comparing replacement options for a 12V, 100A charging system.

Application and Buying Notes

Before buying, check the alternator mount style, pulley layout, and key dimensions against the unit you are replacing. The DXA605 is a Delphi style alternator with a quad leg mount, 55mm inside mounting legs, 159mm mount centre to centre, and M10x1.25 pivot and adjusting holes, so it should only be considered where those details line up.

Also confirm the electrical and drive requirements of the vehicle. This alternator is rated at 12V and 100A, uses an internal regulator, rotates clockwise, and has a 6 groove pulley with a 54mm outside diameter. Those details need to match the charging system and belt arrangement already on the vehicle.

The listed fitment groups include Holden Barina, Holden Cruze, and Opel Corsa, but those names alone are not enough to confirm a correct installation. Use the part number DXA605, the pin code IR127, and the physical measurements to verify the replacement against the original unit before fitting.

If you are comparing against an existing alternator, check both the mount pattern and the pulley section carefully. A mismatch in the number of grooves, pulley diameter, rotation direction, or mounting hole size can prevent installation even when the vehicle family appears similar. This is especially important on mixed platform vehicles where more than one alternator configuration may be used.

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 DXA605 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 100A Delphi Style. Part number DXA605 should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA605, 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 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment by matching part number DXA605, pin code IR127, mount style, pulley section, rotation, and the listed dimensions against the original alternator and vehicle application before purchase or installation.
