Product details

Contact Rating and Mating Cycles

The 77311-102-04LF: The square male pin (0.025" square typical for this series) mates with standard 0.025" square receptacles — common in BergStik-compatible crimp housings and IDC sockets.

RoHS compliant.

Peer Comparison: Position Count Options

The same 77311-series single-row unshrouded header is available in 2 positions (77311-101-02LF) and 20 positions (77311-102-20LF) with identical pitch, current rating, and gold plating — the only difference is the number of pins and the overall length of the part.
