0.100" Pitch, 3-Position Breakaway Header for Board-to-Board Stacking
The 93689-103-03LF: This is a single-row, unshrouded BERGSTIK® header with 3 positions loaded — a breakaway design that snaps to length from a longer strip. The post finish is tin (39.4µin), standard for solder-joint compatibility.
Press-Fit and Solder Termination — One Part, Two Assembly Methods
The termination is listed as both press-fit and solder. The press-fit option allows solderless backplane assembly — the compliant pin compresses into the plated through-hole, creating a gas-tight joint without reflow. The solder tail (0.177" post length) gives a conventional through-hole option for wave or hand soldering. Same part number covers both methods, so the buyer can choose the assembly process at the line.
The part is RoHS compliant.
Peer Comparison: 3-Position vs 2-Position vs Right-Angle
The 6-position right-angle variant 77315-118-06LF changes the orientation to parallel with the board, which alters the z-height budget for mezzanine stacking. The SMT sibling 95293-101-03LF (same 3 positions, same gold finish) eliminates through-hole assembly but requires reflow profile compatibility.
