Product Advantages

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

Fitment-first matching

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 DENSO and replacement references including 12181 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.

Product matching notes

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

How do I confirm CF-12181N fits?

Compare Part No, OE numbers, Lester Numbers, the application records, and the spec table. The page is organized around Toyota 5FD-10, Toyota 5FD-14, Toyota 5FD-15 and related applications.

Which fields matter most?

Start with Voltage: 12V, Amperage: 50A, Rotation: CW, Pulley Class: V1, then cross-check OE numbers Denso 100211-4200, 100211-4201, Original Reference Number 9213933, Toyota 27070-23040.

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 12181. That usually narrows the match quickly.
