It uses an internal regulator, a 6 groove pulley, and a twin leg alternator mount with 56mm inside mounting legs and a 184mm centre-to-centre mount measurement.\u003c\/p\u003e\n\u003cp\u003eIt is listed as suitable for Holden Astra, Barina and Vectra applications with Z18XE, C16SE, C14NZ and C22SEL engines. The fitment information provided also includes Holden Astra applications across multiple model years, but the exact vehicle match still needs to be confirmed against the part number, engine code and mounting details before purchase.\u003c\/p\u003e\n\u003cp\u003eThis alternator is a Bosch-branded rotating electrical component, sold each, with a stated weight of 6.84kg.

The key physical measurements here are the 56mm inside mounting legs, 184mm centre-to-centre mount spacing, 10mm pivot hole diameter and M8 x 1.25 adjusting hole diameter. If those points do not match, the unit may not install correctly even if the vehicle model appears similar.\u003c\/p\u003e\n\u003cp\u003eThe pulley detail matters as well. This alternator uses a 6 groove pulley with a 55mm outside diameter, so the belt arrangement on the vehicle needs to match that setup. A belt or pulley mismatch can create installation issues, noise or charging problems, so it is worth checking the existing unit rather than relying on the model name alone.\u003c\/p\u003e\n\u003cp\u003eThe internal regulator is another important compatibility checkpoint. Some charging systems use different regulator arrangements, and this alternator is specified with an internal regulator for the application it suits. The unit is a 12V, 100A Bosch alternator, so it is intended for vehicles that require that charging specification rather than a lower-output or different-regulated unit.\u003c\/p\u003e\n\u003cp\u003eThis is a new alternator with a one year warranty, and it weighs 6.84kg. That weight and the listed Bosch construction details can be helpful when comparing against a removed unit, especially if you are checking that the replacement is the same style and configuration rather than simply a close-looking alternative.\u003c\/p\u003e\n\u003cp\u003eFor Holden applications, engine code is one of the clearest ways to narrow the correct fitment. The listed engine codes are Z18XE, C16SE, C14NZ and C22SEL, and those should be matched to the vehicle wherever possible. If the car has been modified, has an engine swap, or uses non-standard charging components, the part number and mounting measurements become even more important.\u003c\/p\u003e\n\u003cp\u003eBefore 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.\u003c\/p\u003e\n\u003cp\u003eFor workshop, fleet, and equipment applications, accurate identification of part number BXH1262A 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.\u003c\/p\u003e\n\u003cp\u003eRelevant published details for this unit include Type ALTERNATOR, Unit of Measure EACH, Warranty One Year, Inside Mounting Legs 56mm, Pivot Hole Diameter 10, Pulley Outside Diameter 55mm, Regulator Type Internal, Voltage 12, Mount Cnt to Cnt 184mm, Weight 6.84kg.\u003c\/p\u003e\n\u003cp\u003eAdditional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. BXH1262A, Brand BOSCH, Description Bosch Alternator 12V 100A, Adjusting Hole Diameter M8 x 1.25, Pin Code IR189, Power Rating (Amp) 100, Pulley Section 6 Groove, Suits Unit Make Bosch, Alternator Mount Twin Leg.\u003c\/p\u003e\n\u003cp\u003eBosch Alternator 12V 100A. Part number BXH1262A should be checked first. Listed voltage is 12. Listed output rating is 100. These details form the core reference points used by parts interpreters when confirming the correct replacement.\u003c\/p\u003e\n\u003cp\u003eMount style is Twin Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.\u003c\/p\u003e\n\u003cp\u003eFor part number BXH1262A, 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.\u003c\/p\u003e\n\u003cp\u003eFor a alternator in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 100 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCompatibility note:\u003c\/strong\u003e Please confirm fitment by matching Bosch part number BXH1262A, the listed engine code, the twin leg mounting pattern, the 6 groove pulley, and the 12V 100A specification against the vehicle before ordering.\u003c\/p\u003e\n\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003ch4\u003eWhat part number is this Bosch alternator?\u003c\/h4\u003e\n\u003cp\u003eThe part number listed is BXH1262A.\u003c\/p\u003e\n\u003ch4\u003eWhat voltage and output does it have?\u003c\/h4\u003e\n\u003cp\u003eIt is a 12V alternator with a 100A power rating.\u003c\/p\u003e\n\u003ch4\u003eIs the regulator built in?\u003c\/h4\u003e\n\u003cp\u003eYes.
