Bosch Alternator 12V 150A 1986A00949

This Bosch alternator is listed as a 12V unit with a 150A description and part number 1986A00949. It sits in the rotating electrical group and is identified as an alternator light commercial type, which makes the key checks the electrical rating, mounting style, and application details before ordering.

The alternator uses direct fastening and is described as excluding a vacuum pump. For buyers matching a replacement unit, those two details matter just as much as the Bosch branding or the 12V system rating, because the mounting arrangement and alternator layout must align with the vehicle already in service.

A 12 month warranty is listed for this part. It is manufactured in China and supplied each, with packaging dimensions of 28 cm length, 22.5 cm width, and 22.5 cm height, which is useful when planning freight handling or workshop storage.

The supplied application data includes Mercedes-Benz Sprinter, Vito/Mixto, Viano, Valente, and 5-T / 6-T references, but the fitment list is not detailed enough to treat as a blanket confirmation. Confirm the exact vehicle application and compare the part number 1986A00949 before fitting.

Application and Buying Notes

Before ordering, match the part number 1986A00949 against the original alternator or the vehicle catalogue entry. The listed alternator is a 12V unit with direct fastening and an alternator type that excludes a vacuum pump, so those details should be checked carefully on the vehicle already fitted.

The current rating information is presented in two ways: the product description says 12V 150A, while the specification lists alternator charge current at 200 A. When a replacement part shows multiple electrical figures, it is wise to verify which rating is relevant to your application before purchase so the unit suits the charging system correctly.

The fitment references include Mercedes-Benz Sprinter, Vito / Mixto, Viano, Valente, plus 5-T and 6-T entries, but they are not full model-year or engine lists. Use those references as a starting point only, then confirm the exact vehicle variant, mounting style, and alternator layout against the part number and the old unit.

The listed features focus on materials, corrosion resistance, and a reduction drive design. Those are useful construction details, but they do not replace a fitment check. If your vehicle has a different mounting arrangement, a vacuum pump alternator, or a different electrical requirement, this unit may not be the correct match.

For workshop or retail planning, the unit is supplied each and backed by a 12 month warranty. Keep the packaging size in mind if you are arranging freight, and make sure the replacement is identified by the Bosch part number 1986A00949 rather than by description 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 1986A00949 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.
