OEX Alternator 12V 45A Denso Style DXA416

The OEX Alternator DXA416 is a new 12V, 45A unit built in a Denso style configuration for applications that suit a Denso alternator. It uses an internal regulator, a single leg alternator mount, and a pulley with a 63mm outside diameter and A section belt groove.

This alternator is listed with a mount centre-to-centre measurement of 153mm, a mount leg thickness of 24mm, a pivot hole diameter of 10mm, and an adjusting hole diameter of M8x1.25. Those dimensions matter when comparing the unit to the vehicle’s original alternator and bracket arrangement.

OEX states that its products are sourced from market leading original equipment manufacturers and aftermarket suppliers, with manufacturing from ISO9001 certified factories. The unit is backed by a 3 year passenger / 1 year commercial warranty, which is an important consideration for owners wanting a replacement alternator with clear support terms.

Application and Buying Notes

Before ordering, compare the part number DXA416 and the physical mounting details against the alternator already fitted to the vehicle. The confirmed dimensions here are 153mm mount centre-to-centre, 24mm mount leg thickness, a 10mm pivot hole diameter, and an M8x1.25 adjusting hole diameter. Those measurements need to line up with the brackets and fixing points on the vehicle.

This is a 12V, 45A alternator with an internal regulator and a 63mm A section pulley. That makes the electrical rating and pulley arrangement just as important as the physical fit. If the original unit uses a different pulley section, different output, or an external regulator, it should be checked carefully before purchase.

The listing shows suitability for Denso applications, and the fitment data supplied includes CASE 1825B, CASE 1838, CASE Maxi Sneaker, and Daihatsu Charade references. Because alternator fitment can vary within the same vehicle line, confirm the exact application against the vehicle details and the existing unit rather than relying on vehicle name alone.

At 3.18kg, this is a compact rotating electrical replacement, but physical size alone is not enough to confirm interchange. Check the pulley outside diameter, pulley section, mount style, and regulator type together so the replacement matches the original installation as closely as possible.

Warranty coverage is listed as 3 years for passenger use and 1 year for commercial use. That is useful for comparing supply options, but it does not replace the need to verify fitment and specification compatibility before fitting the 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 DXA416 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 1 ROTATING ELECTRICAL, Part No. DXA416, Brand OEX, Description OEX Alternator 12V 45A Denso Style, Adjusting Hole Diameter M8x1.25, Pin Code IR17, Power Rating (Amp) 45, Pulley Section A, Suits Unit Make Denso, Alternator Mount Single Leg.

OEX Alternator 12V 45A Denso Style. Part number DXA416 should be checked first. Listed voltage is 12. Listed output rating is 45. 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 A. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA416, 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 45 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include CASE 1825B, CASE 1825B 1998, CASE 1825B 1999, CASE 1825B 2000, DAIHATSU CHARADE, DAIHATSU CHARADE 1980. 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.

The listed warranty is 3yr Passenger 1yr Commercial. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by matching part number DXA416, the Denso style application, and the listed mounting and pulley measurements with the vehicle’s original alternator before purchase.
