Application and Buying Notes

Before ordering, compare the part number 439723 and the alternator details against the unit already fitted to the vehicle. The critical checks here are 12V voltage, 150A output, 5 groove pulley, twin leg mount, and the 126mm centre-to-centre mounting measurement.

The connector note is important: this alternator is listed with no connector for revolution counter. If the original unit uses a different connector arrangement, the part may not be a direct match even where the vehicle make appears in the fitment references.

Mounting style matters just as much as electrical output. Confirm the 76mm inside mounting legs, 11 / M10 pivot hole diameter, and double pivot lever fastening before you buy, especially on vehicles where alternator brackets or pulley arrangements have been changed previously.

The unit is identified as a new Valeo alternator with an internal regulator. That combination is useful when replacing a worn or noisy charging unit, but the existing installation still needs a physical match on bracket spacing, pulley section, and connector layout.

If you are comparing this against a removed alternator, use the old unit as the reference point where possible. Checking the label, pulley type, mount spacing, and pin code IR228 will reduce the chance of ordering the wrong replacement.

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 439723 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 150A. Part number 439723 should be checked first. Listed voltage is 12. Listed output rating is 150. These details form the core reference points used by parts interpreters when confirming the correct replacement.

Mount style is Twin Leg. Regulator type is Internal. Pulley configuration is 5 Groove. Those physical and electrical details should line up with the original unit before the replacement is approved for fitment.

For part number 439723, 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 150 should be checked carefully. Incorrect selection can affect installation time, return freight, and equipment availability.

Available application references include MINI MINI, MINI MINI 2010, MINI MINI 2011, MINI MINI 2012. 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 fitment by matching part number 439723 and the listed mounting and connector details to the vehicle’s existing alternator before purchase. Do not rely on vehicle make alone; compare voltage, output, pulley section, mount spacing, and connector arrangement.
