OEX Alternator 12V 150A Denso Style DXA4100

The OEX Alternator 12V 150A Denso Style is a new rotating electrical unit with a 12 volt output, 150 amp power rating and part number DXA4100. It is listed as a Denso style alternator with a pad mount, 6 groove pulley and external regulator, so matching the application details matters before purchase.

This alternator is supplied as a new unit and is identified with pin code ER55, insulated return: no, and pulley outside diameter of 52mm. Those details are important when comparing against the original alternator already fitted to the vehicle, especially where connector style, mounting and pulley layout need to line up exactly.

OEX backs this alternator with a 3 year passenger and 1 year commercial warranty. For buyers replacing a charging system component, the key checks are not just voltage and amperage, but also the physical mount, pulley section, regulator type and unit make listed for the application.

Application and Buying Notes

When replacing an alternator, the most useful checks are the part number, mount style and electrical layout. This unit is DXA4100, 12 volt and 150 amp, with a pad mount, external regulator and ER55 pin code. If any of those details differ from the original alternator, it should be compared carefully before you buy.

The pulley specification matters just as much as the amperage. This alternator uses a 6 groove pulley with a 52mm outside diameter, and the listing states insulated return: no. Those details need to match the vehicle’s charging system arrangement and the alternator already in the engine bay.

Although the product is listed against Jeep Renegade applications, the safest approach is to confirm the vehicle by model year and compare the original unit directly. Alternators can vary by mount, regulator type and connector style even within the same model range, so the part number and physical specifications should be checked together.

The warranty is 3 years for passenger use and 1 year for commercial use, which gives a clear reference point for typical application. It does not replace fitment checking, and it should not be used as a substitute for verifying the Denso style, 12V rating, 150A output and ER55 pin code against the vehicle’s current 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 DXA4100 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. Part number DXA4100 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 Pad. Regulator type is External. 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 DXA4100, 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: Please confirm fitment by matching the DXA4100 part number, Denso style application, pad mount, 6 groove pulley, 52mm pulley outside diameter, external regulator and ER55 pin code with the alternator currently fitted to the vehicle. Use the vehicle details and original unit as the final check before ordering.
