Application and Buying Notes

Check the part number 439397 and OEM number 439223 against the unit being replaced before ordering. Alternators can look similar externally while differing in pulley section, mount style, connector arrangement, or charge output, so matching the listed details matters.

This unit is a 12V, 90A alternator with a 6 groove pulley, clockwise rotation, a twin leg mount, and an internal regulator. The mount centre to centre measurement is 127mm, the inside mounting legs are 75mm, and the pulley outside diameter is 50mm, so these dimensions should be compared carefully with the existing alternator and bracket arrangement.

The connector note is specific: no connector for revolution counter. If your vehicle or replacement unit uses a different connector arrangement, that needs to be checked before purchase. The pin code is IR122, which is another useful identifier when matching the correct application.

Valeo is noted as a leading OE manufacturer and supplier for many euro vehicles, which supports confidence in the product class, but it does not replace fitment checking. The safe approach is to confirm the vehicle application, mounting pattern, pulley configuration, and electrical connection details together 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 439397 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.
