0.100" Pitch, 10-Position Unshrouded Header
The 77311-101-10LF: The 0.230" mating pin length gives a solid wipe depth into a standard female socket.
The unshrouded design keeps the z-height low (0.100" insulation height above board), which matters in tight card-to-card stacking.
The 77311-101-14LF is the 14-position sibling — same pitch, same plating, same 0.425" overall length. The 77311-101-02LF is the 2-position version. All share the identical footprint and termination, so swapping position counts requires no board layout change beyond the pin count. The 77311-102-20LF is a 20-position variant with a slightly longer overall contact length (0.465") — the extra length accommodates a thicker board or a deeper mating socket. If your design needs more than 10 positions on a single row, the 20-position version fits the same pitch and plating spec.
