FAQ
Q: Is FW-C-3M-B the male or female side?
A: FW-C-3M-B is the male plug (pin side); FW-C-3F-B is the female receptacle (socket side). Both are included in this kit.
Q: What wire gauge is compatible?
A: The FW-C 2.3mm terminals accept 0.5–1.5mm² wire (AWG 20–16). Use a Furukawa-spec or equivalent ratchet crimping tool for reliable termination.
Q: Is DJ7031Y-2.3 the same connector?
A: Yes. DJ7031Y-2.3 is the Chinese OEM cross-reference for the Furukawa FW-C-3M-B / FW-C-3F-B pair. Dimensions and terminal pitch are identical.
