OEX Alternator 12V 150A Denso Style DXA4096

The OEX DXA4096 alternator is a 12V, 150A unit in Denso style, supplied new as a twin-leg alternator with a 4 groove pulley. It is listed with a 52mm inside mounting leg dimension, 184mm mount centre-to-centre, and a 60mm pulley outside diameter.

This alternator uses an external regulator and is identified with pin code ER51. It is noted as one of two identical-looking alternators with different ECU control regulator functions, so confirmation by OE number is recommended before purchase.

For applications using a Denso-type alternator, the key checks are the mount style, pulley arrangement, regulator function, and OE reference. The part is supplied under OEX part number DXA4096 and is described as a new rotating electrical component.

Application and Buying Notes

This alternator suits Denso-style applications and carries the OEX part number DXA4096, but the important caution is the note about two visually similar alternators with different ECU control regulator functions. That means a visual match alone is not enough; the OE number should be checked against the original unit before you commit to the part.

The practical identifiers to compare are the 12V system voltage, 150A output, twin-leg mount, 52mm inside mounting legs, 184mm mount centre-to-centre, and 4 groove pulley with a 60mm outside diameter. If any of those dimensions or the regulator arrangement differs from the removed alternator, it is worth stopping and verifying before installation.

This is a new alternator, supplied as an each unit, with an external regulator and pin code ER51. The warranty listed is 3 years for passenger use and 1 year for commercial use. As with any charging system component, correct identification matters more than assumptions based on appearance, especially when ECU control functions are involved.

For the fitment records provided, Chrysler PT Cruiser applications are shown across model years 2004 through 2010. Even with that application note, the safest approach is to compare the OE number, mounting points, and pulley setup on the vehicle to the details of this alternator. That is the best way to avoid receiving the wrong regulator version.

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 DXA4096 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 150A Denso Style - See Note. Part number DXA4096 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is External. Pulley configuration is 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4096, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by checking the OE number, ECU control regulator function, mounting dimensions, pulley type, and application details against the vehicle’s original alternator before ordering.
