OEX Alternator 12V 200A Denso Style DXA4127

The OEX Alternator DXA4127 is a 12V, 200A alternator in Denso style, supplied as a new unit for rotating electrical applications. It is listed with a pad mount, 60mm mount centre to centre, 20mm mount leg thickness, and a 10mm mount hole diameter, so those physical details are important when checking a replacement.

This alternator uses an internal regulator and a 4 groove pulley with a 60mm outside diameter. That combination makes the pulley and mounting dimensions just as important as the electrical rating, especially where the original unit is a Denso type and the vehicle’s belt setup needs to match exactly.

OEX identifies this unit under part number DXA4127, with a power rating of 200 amps and a weight of 7.22kg. It is covered by a 3 year warranty for passenger use and 1 year for commercial use, which is useful context when comparing it with the original alternator and other aftermarket options.

Application and Buying Notes

Before ordering, confirm the replacement alternator matches the vehicle’s original unit by part number, mount style and pulley details. This OEX unit is DXA4127, 12V, 200A, with a Denso style fitment, internal regulator, 4 groove pulley, 60mm pulley outside diameter, and a pad mount arrangement. Those measurements matter because alternators that look similar can still differ in the mounting face, bolt size or pulley setup.

The listed mount dimensions are especially useful when comparing against the old unit. Check the 10mm mount hole diameter, 20mm mount leg thickness and 60mm mount centre to centre before fitting. If the original alternator uses a different mounting pattern, belt alignment or pulley section, it may not be a suitable replacement even if the electrical output appears close.

Because this alternator is rated at 200A, it is important to confirm the vehicle actually requires that output level. The current draw on the vehicle, factory charging system design and the correct Denso-style application should all be checked together. A high-output alternator can only be used as intended when the physical fitment and electrical setup both match the application.

The unit is supplied new and backed by a 3 year passenger / 1 year commercial warranty, which gives a clear service context, but warranty cover does not replace the need to verify fitment first. Matching the part number DXA4127, the Denso unit type, and the stated mounting and pulley measurements is the safest way to avoid installation issues.

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 DXA4127 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 200A Denso Style. Part number DXA4127 should be checked first. Listed voltage is 12. Listed output rating is 200. 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 4 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number DXA4127, 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 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Always confirm compatibility using part number DXA4127, the Denso style application, and the listed mount and pulley measurements before purchase. Vehicle fitment should be checked against the original alternator, especially if the existing unit differs in pad mount design, pulley section, or bolt spacing.
