OEX Alternator 12V 150A Denso Style DXA4118

The OEX Alternator 12V 150A Denso Style is a new rotating electrical unit with a 12 volt output, 150 amp power rating, and a Denso-style application profile. It is identified by part number DXA4118 and uses an internal regulator, which is important when matching the alternator to the vehicle’s charging system.

This unit is specified with a 6 groove pulley, a 54mm pulley outside diameter, a pad mount, and IR228 pin code. It is supplied as each and weighs 5.64kg, so the mounting style and physical dimensions should be checked carefully against the existing alternator before ordering.

OEX backs this alternator with a 3 year passenger and 1 year commercial warranty. The product is listed as new, not remanufactured, and is part of the OEX alternator range for vehicles that call for a Denso unit with the stated electrical and mounting details.

Application and Buying Notes

When matching this alternator, the key checks are the 12V charging system, 150A output, Denso style application, and DXA4118 part number. The alternator is a pad mount unit with a 6 groove pulley and 54mm pulley outside diameter, so those dimensions need to line up with the vehicle and belt setup already fitted.

The internal regulator and IR228 pin code are also important. If the original unit uses a different regulator arrangement or connector coding, the alternator may not suit even if the vehicle is in the same model family. That is why the part number, plug style, and mounting points should be confirmed before fitting.

This alternator is listed with 10mm adjusting hole diameter and 13mm pivot hole diameter, which are useful checks when comparing to the old unit or mount brackets. If you are replacing a worn or failed alternator, compare the old part directly and make sure the physical dimensions match, not just the vehicle model name.

The unit is new and supplied each, with a listed weight of 5.64kg. For workshop or trade buying, the 3 year passenger and 1 year commercial warranty can be considered alongside the vehicle application, but it does not replace a proper fitment check against the original Denso-style 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 DXA4118 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.

Additional published details for cross-checking include Product Group 2 ALTERNATORS, Part No. DXA4118, Brand OEX, Description OEX Alternator 12V 150A Denso Style, Adjusting Hole Diameter 10, Pivot Hole Diameter 13, Pulley Outside Diameter 54mm, Regulator Type Internal, Voltage 12, Item Type Alternator.

OEX Alternator 12V 150A Denso Style. Part number DXA4118 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 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 DXA4118, 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.

Available application references include JAGUAR F-PACE, JAGUAR F-PACE 2015, JAGUAR F-PACE 2016, JAGUAR F-PACE 2017, LAND ROVER DISCOVERY, LAND ROVER DISCOVERY 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.

Compatibility note: Confirm fitment by matching part number DXA4118, Denso style application details, 12V/150A output, IR228 pin code, 6 groove pulley, and pad mount dimensions against the original alternator and vehicle requirements before ordering.
