Pitch, Pin Count, and Board Fit
The 77313-401-10LF: The row spacing is also 0.100" (2.54mm), so the footprint matches a 2x5 pattern of 0.025" square pins.
The UL94 V-0 rated thermoplastic housing means the connector can be used in equipment that requires a flame-retardant enclosure.
Peer Comparison: Tin vs Gold Mating Finish
The closest functional sibling is 77313-101-10LF — identical pin count, pitch, row count, and body. The difference is the mating finish: this 77313-401-10LF uses tin (78.7µin) on the mating surface, while the 77313-101-10LF uses gold or gold GXT™ (30.0µin). If your application demands higher mating cycle life or better corrosion resistance, the gold-plated version is the better call. For a one-time assembly in a benign environment, the tin version saves cost.
