Bosch Alternator 12V 130A Pad Mount Internal Regulator BXA1203N

The Bosch Alternator 12V 130A is a new rotating electrical unit with a pad mount and internal regulator, supplied under part number BXA1203N. It is rated at 130 amps and 12 volts, with clockwise rotation and a 17mm shaft diameter, so matching the electrical and mounting details is essential before purchase.

This alternator is listed as Bosch brand, made as a new unit rather than remanufactured, and it uses pin code IR21 with a centre-to-centre mount measurement of 175mm. Those identifiers matter when checking a replacement, especially where the original alternator layout, plug style, and mounting pattern need to line up.

The unit is supplied each and carries a one year warranty. It is described as suitable for a range of Ford applications in the fitment data, including Ford Explorer entries from 1996 through 2006 and Ford F-250 references, but the buyer should confirm the exact vehicle match using the part number and application details before ordering.

Application and Buying Notes

When replacing an alternator, the safest comparison points are the part number BXA1203N, the 12V system voltage, the 130A output rating, and the physical details such as the pad mount, 175mm mount centre to centre, and 17mm shaft diameter. If any of those do not match the original unit, the alternator may not suit the vehicle even if the make appears similar.

The internal regulator and clockwise rotation are important because alternators are not universal by appearance alone. The plug identification shown here is IR21, so the connector style needs to be checked against the vehicle’s existing harness or the old alternator before purchase.

This unit is described as a Bosch alternator and is supplied new, which may suit buyers who want a direct replacement format rather than a rebuilt component. The one year warranty applies to the part as supplied, but it does not remove the need to verify dimensions, mounting position, and electrical specification first.

The listed fitment references include Ford Explorer entries from 1996 to 2006 and Ford F-250 references, but those names should be treated as a guide rather than a blanket guarantee. Always confirm the exact application by part number, mounting arrangement, and connector code before fitting or finalising an order.

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 BXA1203N 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.
