Bosch Alternator 12V 200A Direct Fastening Part No. 1986A00950

The Bosch Alternator 12V 200A is a rotating electrical component supplied as an each unit and identified by part number 1986A00950. It is a passenger alternator with a 12 volt system, a 200 amp power rating, and direct fastening mounting, so the fitment check needs to start with those exact details rather than appearance alone.

This alternator is listed as an alternator type excl. vacuum pump, which is an important distinction when comparing against the unit already fitted to the vehicle. The charging specification is 200A, and the unit is intended to deliver high charging output as part of the vehicle’s electrical system where the application matches.

Bosch states the unit is manufactured to the same rigorous production standard as OE parts and is designed for high performance in extreme conditions. For buyers replacing a worn charging unit, the most useful reference points are the 12V system, 200A output, direct fastening arrangement, and Bosch part number 1986A00950.

Packaging dimensions are 28 cm long, 22.5 cm wide, and 22.5 cm high, and the alternator is manufactured in China. A 12 month warranty applies, which gives a useful baseline for retail replacement work when the correct application is confirmed.

Application and Buying Notes

For a correct replacement, match the Bosch part number 1986A00950 first, then confirm the vehicle uses a 12V charging system with a 200A alternator specification. The fastening type is direct fastening, so the mounting style needs to line up with the vehicle’s brackets and hardware rather than relying on a visual comparison alone.

The 200A output is a useful reference for vehicles with higher electrical demand, but it should still be matched to the original specification fitted to the vehicle. A different amperage rating can affect compatibility, so the replacement should be checked against the vehicle’s original charging output and application details.

Bosch recommends additional repair attention to the V-Belt or V-Ribbed Belt. In practice, it is sensible to inspect the belt condition, drive system wear, and related charging components at the same time, particularly when the existing alternator has been in service for some time.

The listed 12 month warranty applies to the product as supplied, but warranty does not replace the need to verify fitment before installation. Keep the part number, voltage, fastening style, and alternator type in hand when comparing against the removed unit or vehicle records.

If you are working from vehicle details rather than a removed part, confirm the charging system specification carefully before purchase. Matching the 12V system, 200A output, direct fastening mount, and excl. vacuum pump design will narrow the application correctly and reduce the risk of ordering the wrong alternator.

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 1986A00950 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 200A. Part number 1986A00950 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.

For part number 1986A00950, 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 voltage 12 and output 200 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Compatibility note: Confirm fitment using Bosch part number 1986A00950, the 12V / 200A specification, direct fastening mount, and the alternator type excl. vacuum pump before ordering.
