Bosch Alternator 12V 150A 0124615046

This Bosch alternator is a new 12V unit with a 150A charge current, part number 0124615046. It is supplied as an alternator only, with an internal regulator and a single leg mount, so it suits applications designed around those physical and electrical specifications.

The unit uses a 6 groove multi-belt pulley with a 50mm pulley outside diameter and an alternator type listed as excl. vacuum pump. For buyers matching a replacement unit, those details matter just as much as voltage and amperage, because pulley style, mounting arrangement and regulator type all need to align with the original setup.

Bosch lists this alternator as made from high quality raw materials, corrosion resistant, and fitted with a reduction drive to maintain continual speeds for easier starting. It is a new rotating electrical component and carries a one year warranty.

If you are replacing a charging system component, the key identifiers here are Bosch, 12V, 150A, and part number 0124615046. Checking those details against the removed unit before ordering is the safest way to avoid a mismatch.

Application and Buying Notes

When checking compatibility, start with the part number 0124615046 and confirm the replacement alternator matches the original unit’s 12V system, 150A charge current, internal regulator, and single leg mounting style. These are the practical checkpoints that usually decide whether the part will physically and electrically suit the vehicle.

The pulley details are also important. This alternator has a 6 groove multi-belt pulley with a 50mm outside diameter, so the belt layout on the vehicle needs to match. If the belt type or groove count differs, the alternator may not align correctly with the drive system.

Bosch notes this alternator as excl. vacuum pump, which is another point to confirm before ordering. If the removed alternator includes a vacuum pump arrangement, this unit is not the same configuration and should not be assumed to interchange.

A replacement alternator is often fitted alongside belt service work, and Bosch lists V-belt or V-ribbed belt as a recommended additional repair. That does not mean every vehicle needs both items, but it is a sensible checkpoint when a charging issue has also affected belt condition or drive performance.

This is a new unit, not remanufactured, and it is sold each. If you are comparing options, make sure you are comparing like for like on condition, output rating, regulator type and pulley configuration rather than relying on appearance alone.

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 0124615046 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.

Bosch Alternator 12V 150A. Part number 0124615046 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Single 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.

For part number 0124615046, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Where no verified application list is available, the part number, mounting details, connector style, and published specifications should be used as the primary selection criteria.

In the absence of a verified fitment list, the safest approach is to compare the removed unit directly with the listed product details. That includes checking the housing style, pulley layout, regulator arrangement, and any visible identification numbers before supply is approved.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Please confirm fitment by matching the Bosch part number 0124615046, the 12V / 150A rating, the internal regulator, the single leg mount, and the 6 groove pulley arrangement against the vehicle’s original alternator and application details before ordering.
