Valeo Alternator 12V 150A Part No. 439912

Valeo Alternator 12V 150A, Part No. 439912, is a new alternator sold each with a 12 volt electrical system and a 150 amp charge current. It is a Valeo unit with internal regulator, twin leg alternator mount, and four-point mounting, so it is important to match the mounting style and electrical details before ordering.

This alternator uses a 6 groove pulley with a 53mm outside diameter and has a left-hand 80 degree position designation (L 80). It is listed with pin code IR168 and comes with no connector for revolution counter, which makes the connector arrangement a key checkpoint when comparing against the unit being replaced.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles, and this part is identified under the rotating electrical category. The unit weighs 7.73kg and is supplied with no warranty, so buyers should confirm the application carefully against the part number 439912 and the alternator details before purchase.

Application and Buying Notes

When replacing an alternator, the part number 439912 is the most reliable starting point, but it should still be checked against the physical unit and vehicle application. On this Valeo alternator, the 12V system, 150A output, twin leg mount, and four-point mounting all need to line up with the replacement position to avoid installation issues.

The pulley and connector details matter just as much as the electrical rating. This unit has a 6 groove pulley with a 53mm outside diameter, an internal regulator, and no connector for revolution counter, so the existing alternator should be compared carefully for pulley style, connector layout, and any mounting differences before fitting.

Weight and packaging can also help confirm the match. At 7.73kg, this is a substantial rotating electrical component, and the listed L 80 position plus IR168 pin code provide extra identifiers that can be used when checking against the removed alternator or vehicle records.

If the vehicle has previously been repaired or converted, do not rely on model name alone. The available fitment references point to Ford Mondeo applications, but alternators are commonly affected by engine type, charging system variation, and connector differences, so the safest approach is to confirm the vehicle details and the alternator part number together.

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 439912 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.
