Peer comparison: 77311-118-02LF and 77311-101-02LF

Both 77311-118-02LF and 77311-101-02LF are identical in pitch, circuit count, plating, and current rating — the difference is the overall contact length: 0.465" (11.81mm) for this part vs 0.450" (11.43mm) for 77311-118-02LF and 0.425" (10.80mm) for 77311-101-02LF. The mating length and post length shift accordingly, so the board stack-up and mating receptacle clearance must be checked against the drawing.
