FAQ

Q1:What is the interchange relation between 3415691 and 4930794?
A: Mechanically fully bolt-on interchangeable, same mounting footprint, connector and pulley. 3415691 is superseded by 4930794. 4930794 is the latest-generation version with upgraded rectifier and better heat-dissipation performance.

Q2：What does the "C" prefix mean in C3415691?
A: The "C" prefix (C3415691) indicates DCEC (Dongfeng Cummins) factory packaging for the China domestic market. The alternator assembly itself — electrical rating, internal components, mounting and connector — is identical to the non-C 3415691. Both are genuine Cummins parts and fully interchangeable.

Q3：IS 3415691 still in production, or only available as stock?
A: 3415691 has been officially superseded by 4930794 in Cummins' current parts catalog. New OEM production primarily runs under the 4930794 part number. However, 3415691 remains widely available as genuine service stock and is still in high demand for older equipment maintenance where customers require the exact original part number. We keep both 3415691 and 4930794 in stock.
