Valeo Alternator 12V 140A Part No. 439608

The Valeo Alternator 12V 140A, part no. 439608, is a new rotating electrical unit supplied as an each item. It is rated at 140 amps, runs on 12 volts, and uses an internal regulator, which makes the key electrical details easy to check before ordering.

This alternator is identified with pin code IR139 and a 6 groove pulley with a 50mm outside diameter. It has a quad leg alternator mount, four-point mounting, and a position / degree listed as R 90, so matching the physical layout matters as much as matching the electrical rating.

Valeo lists this unit as a new alternator with a one year warranty. The weight is 6.96kg, and the connector detail notes no connector for revolution counter, which is an important point to confirm against the original unit before purchase.

Application and Buying Notes

When choosing an alternator, the first checks should be the part number 439608, the 12V system voltage, and the 140A output rating. Those details need to align with the vehicle’s charging system requirements, but the physical layout is just as important on this Valeo unit because it uses a quad leg mount, four-point mounting, and an R 90 position.

The pulley and connector details are worth checking closely. This alternator has a 6 groove pulley with a 50mm outside diameter and no connector for revolution counter. If the original alternator differs in groove count, pulley diameter, mounting arrangement, or sensor connection, the replacement may not suit the vehicle even if the electrical rating looks similar.

The internal regulator is another useful comparison point. If the vehicle’s charging system is set up for a different regulator arrangement, the alternator may not be a direct match. Weight is listed at 6.96kg, which can also help when comparing the unit in hand with the one being replaced.

For vehicles listed in the fitment data, always confirm the exact application using the model, year range, and the original alternator details. The fitment examples include AUDI A3, AUDI TT, SKODA OCTAVIA, SKODA SUPERB, VOLKSWAGEN AMAROK, VOLKSWAGEN CC, VOLKSWAGEN MULTIVAN, VOLKSWAGEN PASSAT, VOLKSWAGEN TRANSPORTER, and VOLKSWAGEN TRANSPORTER / CARAVELLE, but alternator variations can still exist within the same model family.

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 439608 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.

Additional published details for cross-checking include Product Group 1 ROTATING ELECTRICAL, Part No. 439608, Brand VALEO, Description Valeo Alternator 12V 140A, Pin Code IR139, Pulley Outside Diameter 50mm, Regulator Type Internal, Voltage 12, New / Reman. New, Position / Degree R 90.

Valeo Alternator 12V 140A. Part number 439608 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 439608, 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 A3, AUDI A3 2003, AUDI A3 2004, AUDI A3 2005, SKODA OCTAVIA, SKODA OCTAVIA 2005. 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.

Compatibility note: Confirm compatibility by matching part number 439608, the 12V 140A rating, pulley details, mount type, regulator type, connector arrangement, and the vehicle application before ordering.
