Application and Buying Notes

Before ordering, compare the part number DXA4025, OEM number 100211-8740-PO, and the alternator layout on the vehicle. This unit is a 12V, 95A Denso-style alternator with a single-leg mount, so the mounting style needs to match the original unit as well as the electrical requirements.

The pulley and mounting measurements are just as important as the electrical rating. Check the 6 groove pulley, 62mm pulley outside diameter, 56mm mount leg thickness, 153mm mount centre-to-centre measurement, and 8mm adjusting hole diameter against the existing alternator before purchase.

The internal regulator and IR2 pin code also need to align with the application. A correct physical fit does not automatically mean the wiring plug, regulator setup, or belt arrangement will be correct, so the vehicle’s original unit should be matched carefully.

This alternator is listed as new and carries a 3yr Passenger / 1yr Commercial warranty. Warranty terms are useful, but they do not replace fitment checking, particularly where the vehicle is an older Honda Prelude application and the original unit may vary by build details or market.

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 DXA4025 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.

For part number DXA4025, 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 95 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm compatibility by checking the part number DXA4025, OEM number 100211-8740-PO, Denso-style application, single-leg mount, 12V 95A specification, pulley details, and the vehicle’s original alternator before ordering.
