OEX Alternator 12V 110A Denso Style DXA4023

The OEX Alternator DXA4023 is a new 12V, 110A unit made in a Denso style configuration for rotating electrical applications. It is listed as a single leg alternator with an internal regulator, a 6 groove pulley, and a 62mm pulley outside diameter, so the physical mounting and belt drive details need to match the vehicle before purchase.

This alternator is supplied under the OEX brand and is identified with Part No. DXA4023 and Pin Code IR11. The listed mount leg thickness is 56mm, the mount centre to centre measurement is 157mm, the pivot hole diameter is 10mm, and the adjusting hole diameter is 12mm. Those dimensions are the key checks for confirming whether the unit will line up correctly in the vehicle.

At 110 amps, this alternator is intended for vehicles that require a 12V charging system with the same Denso-style layout and mounting pattern. The unit weighs 6.1kg and is sold each. Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use, which is useful when comparing replacement options for a road vehicle or work vehicle.

OEX products are described as being sourced from market leading original equipment manufacturers and aftermarket suppliers, and from ISO9001 certified factories. That does not replace fitment checking, but it does give context for buyers looking for a new replacement alternator with clearly stated dimensions and a defined part number.

Application and Buying Notes

Before buying, check the existing alternator against the listed identifiers: Part No. DXA4023, Pin Code IR11, 12V voltage, 110A output and Denso style construction. Those details matter because a charging system can look similar on the vehicle but still differ in the mounting leg, pulley arrangement or regulator type.

The physical measurements are just as important as the electrical rating. This unit is listed with a 56mm mount leg thickness, 157mm mount centre to centre, a 10mm pivot hole, a 12mm adjusting hole and a 62mm outside diameter 6 groove pulley. If any of those dimensions differ from the existing unit, it should be checked carefully before ordering.

This alternator is a single leg type with an internal regulator, so it suits applications built around that layout rather than units with a different mounting system or external regulation. The fact it is a new unit, not remanufactured, may be important for buyers wanting a direct replacement with fresh components, but the vehicle still needs to be matched by specification rather than appearance alone.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That is useful when comparing replacement parts, but it does not remove the need to confirm the mounting pattern, pulley section and application details on the vehicle currently fitted.

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 DXA4023 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 110A Denso Style. Part number DXA4023 should be checked first. Listed voltage is 12. Listed output rating is 110. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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 DXA4023, 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.

Compatibility note: Confirm fitment by matching the part number DXA4023, the Denso style unit make, the 12V 110A specification, and the measured mounting and pulley details against the vehicle already fitted with the alternator.
