Valeo Alternator 12V 140A 439642

Valeo Alternator 12V 140A, part number 439642, is a new rotating electrical unit supplied as each. It is listed with a 140A charge current, internal regulator, and 12V operation, which are the key details to check against the vehicle application before ordering.

This alternator uses a 6 groove pulley, quad leg alternator mount, and four-point mounting arrangement. The mounting measurements supplied are 61mm inside mounting legs and 127mm mount centre to centre, with M8x1.25 / 8.5 pivot and adjusting hole diameters.

The unit is identified as Valeo brand, suits unit make Valeo, and carries pin code IR201. It also has no connector for revolution counter, so connector style should be matched carefully to the vehicle’s existing setup before fitment is assumed.

Application and Buying Notes

Before ordering, match the key identifiers on the existing unit with this alternator’s part number 439642, 12V output, and 140A charge rating. Those three details are the quickest way to narrow the check, but they should be used together with the mounting measurements and connector style rather than on their own.

The mounting setup is specific: 61mm inside mounting legs, 127mm mount centre to centre, M8x1.25 / 8.5 pivot and adjusting holes, and four-point mounting with a quad leg alternator mount. If the old alternator differs in leg spacing, hole size, or mounting pattern, it is not a safe assumption that it will interchange.

Pulley configuration matters as much as electrical output. This unit has a 50mm pulley with a 6 groove section, so the belt type and groove count need to align with the vehicle’s drive arrangement. The note that there is no connector for revolution counter also means the plug arrangement should be checked against the vehicle before fitting.

Valeo is identified here as a leading OE manufacturer and supplier for many euro vehicles, but that does not remove the need to verify application details. Use the listed dimensions, pin code IR201, and existing alternator match-up as the final check, especially when replacing a unit on an Audi A4 or Audi Q5 application.

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 439642 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.

Valeo Alternator 12V 140A. Part number 439642 should be checked first. Listed voltage is 12. Listed output rating is 140. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Quad Leg. Regulator type is Internal. Pulley configuration is 6 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439642, 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 in workshop, fleet, trade, agricultural, or construction service, the listed voltage 12 and output 140 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include AUDI A4, AUDI A4 2007, AUDI A4 2008, AUDI A4 2009. Even with application listings, final confirmation should still be based on the exact unit being replaced and the service requirements of the vehicle or machine.

The listed warranty is One Year. Warranty terms should be considered alongside correct application and part identification, as warranty does not replace fitment confirmation.

Compatibility note: Confirm compatibility by checking part number 439642, 12V system voltage, 140A output, 6 groove pulley, four-point mounting, and the connector arrangement against the existing alternator and vehicle application before purchase.
