OEX Alternator 12V 130A Denso Style DXA4115

The OEX Alternator DXA4115 is a new 12V, 130A unit made to suit Denso applications, with a twin leg alternator mount and internal regulator. It is supplied as a 7 groove pulley alternator with a 52mm pulley outside diameter, so the pulley layout and mounting arrangement are important checks before fitting.

This unit has a part number of DXA4115, a Pin Code of IR201, and a mount centre to centre measurement of 168mm. The inside mounting legs measure 43mm, the pivot hole diameter is 11 / M10, and the adjusting hole diameter is 10, which gives you several useful reference points when comparing against the original alternator.

OEX lists this alternator as new rather than remanufactured, with a weight of 5.1kg and a warranty of 3yr Passenger or 1yr Commercial. For buyers comparing replacement charging components, the key identifiers here are the 12V system, 130 amp output, Denso style construction, and the internal regulator with single LIN terminal option noted for this unit.

Application and Buying Notes

Before ordering, compare the part number DXA4115 and the Denso style application against the alternator currently fitted to the vehicle. The important physical checks are the twin leg mount, 168mm mount centre to centre, 43mm inside mounting legs, 11 / M10 pivot hole diameter, and 10mm adjusting hole diameter.

The charging specification is 12V at 130A, so this unit is intended to replace a like-for-like alternator where that output is required. The pulley is a 7 groove design with a 52mm outside diameter, which needs to match the belt arrangement already on the vehicle.

This alternator uses an internal regulator and the note supplied for the unit states a voltage regulator with single LIN terminal. If the original alternator uses an S terminal or RLO terminal, different part numbers are listed in the product note: DXA4000 for S terminal and DXA4066 for RLO terminal. That makes the regulator terminal type a key buying check, not a detail to overlook.

The alternator is new and backed by a 3yr Passenger or 1yr Commercial warranty. That warranty is useful, but it does not replace the need to confirm the physical fit, pulley configuration, mount style, and regulator terminal arrangement before fitting. If the old unit is available, matching it side by side is the safest way to confirm the application.

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 DXA4115 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. DXA4115, Brand OEX, Description OEX Alternator 12V 130A Denso Style, Adjusting Hole Diameter 10, Pin Code IR201, Power Rating (Amp) 130, Pulley Section 7 Groove, Suits Unit Make Denso.

OEX Alternator 12V 130A Denso Style. Part number DXA4115 should be checked first. Listed voltage is 12. Listed output rating is 130. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 7 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4115, 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 130 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include TOYOTA HIACE, TOYOTA HIACE / COMMUTER, TOYOTA HIACE / COMMUTER 2005, TOYOTA HIACE / COMMUTER 2006. 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 DXA4115, Denso style application details, mount measurements, pulley configuration, and regulator terminal type before purchase.
