OEX Alternator 12V 120A Bosch Style BXA090

The OEX Alternator BXA090 is a 12V, 120A passenger alternator in Bosch style, supplied as one unit each. It sits in the rotating electrical group and is listed under alternators, making it a relevant replacement option when you need to match the electrical output and style rather than rely on a visual comparison alone.

This part carries OEX part number BXA090 and is backed by a 3 year passenger / 1 year commercial warranty. For buyers comparing options, the key identifiers here are the 12V system, 120A output, Bosch style construction, and the BXA090 part number, all of which should be checked against the vehicle application before purchase.

OEX states that its products are sourced from market leading Original Equipment Manufacturers and aftermarket suppliers, and that they come from ISO9001 certified factories with engineering, testing, and quality control procedures in place. That matters when selecting a replacement alternator, because correct output and consistent build quality are both important in charging system service.

Application and Buying Notes

When replacing an alternator, the most useful checks are system voltage, output rating, mounting style, and the part number. In this case, the important identifiers are 12V, 120A, Bosch style, and BXA090. Those details should be compared with the original unit and the vehicle application so the replacement matches the charging system requirements.

Fitment data provided for this item points to Holden Astra applications, including 2006 through 2010 model years. That is helpful, but alternators can vary by engine, build date, connector arrangement, and pulley or mounting details, so it is still wise to confirm the removed unit against BXA090 before fitting.

The warranty is listed as 3 years for passenger use and 1 year for commercial use. If the vehicle is used in a commercial setting, that shorter warranty period is the applicable one. It is also worth checking installation condition, belt wear, wiring condition, and battery health, because a new alternator cannot correct unrelated charging faults elsewhere in the system.

OEX notes that its products are sourced from established OEM and aftermarket suppliers and produced in ISO9001 certified factories. For the buyer, that suggests a product made under controlled quality procedures, but the practical purchase decision should still rest on the confirmed application, the 120A output requirement, and the matching part number.

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 BXA090 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 120A Bosch Style. Part number BXA090 should be checked first. These details form the core reference points used by parts interpreters when confirming the correct replacement.

For part number BXA090, 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 passenger in workshop, fleet, trade, agricultural, or construction service, the listed electrical specification should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include HOLDEN ASTRA, HOLDEN ASTRA 2006, HOLDEN ASTRA 2007, HOLDEN ASTRA 2008. 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: Please confirm compatibility by matching part number BXA090 and the vehicle’s alternator application details before ordering. Fitment should be checked against the original unit, including 12V system requirements, 120A output, and Bosch style configuration.
