Product Advantages

Alternator matching focuses on amperage, voltage, pulley configuration, regulator/fan design, plugs, and OE replacement references.

Fitment-first matching

CF-12387N is prepared for alternator sourcing with Part No, OE, Lester number, and application records checked together.

Quality and test focus

Core specifications such as voltage, power or amperage, rotation, teeth, and design are reviewed before sample or bulk quotation.

Replacement sourcing support

MFR BOSCH and replacement references including 12387 help buyers compare existing units and reduce wrong-part risk.

Inquiry-ready supply

Share target quantity, destination, sample need, and packaging requirement so Crankvia can confirm the practical supply path.

Application Information

Application records are provided as compatibility references. Confirm OE number, vehicle configuration, engine, and market version before final ordering.

Product matching notes

Use these checks together with the application table before final ordering.

How do I confirm CF-12387N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Mercedes-Benz Unitog U-300, Mercedes-Benz Unitog U-400, Mercedes-Benz Unitog U-500 and related applications.

Which fields matter most?

Start with Voltage: 24V, Amperage: 80A, Rotation: CW, Pulley Class: S9, then cross-check OE numbers Audi, Volkswagen 2Z0 903 015, Bosch 0 124 555 001, 0 124 555 002.

What if I only have a photo or partial number?

Share label photos, drive-end and connector shots, and any partial number or Lester Numbers 12387. That usually narrows the match quickly.
