Application and Buying Notes

Before ordering, confirm the alternator part number 439206 against the unit being replaced, then compare the 12V rating, 90A charge current, direct mount arrangement, and 5 groove pulley. Those are the main practical checks that help avoid a mismatch when changing a rotating electrical component.

The listed regulator type is internal, which means the replacement needs to match the vehicle’s charging system design. The connector detail is also important here because this unit is listed with no connector for revolution counter, so the existing harness and connection points should be inspected carefully before purchase.

Physical dimensions matter with alternators as much as electrical output. This Valeo unit has a 52mm pulley outside diameter, an 8mm pivot hole diameter, and a weight of 5.53kg, all of which are useful comparison points when checking clearance, bracket alignment, and whether the old alternator matches the replacement profile.

For the fitment shown here, the applications are listed for Mercedes-Benz A-Class models across the years shown. Even so, vehicle specifics can vary within a model range, so it is best to confirm the part number, mounting style, pulley section, and regulator type against the original unit rather than relying on model name 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 439206 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.
