The TE Connectivity 5555077-1 is a 6p6c modular jack — the 6-position, 6-contact variant that accepts RJ11, RJ12, RJ14, and RJ25 plugs. It is unshielded, right-angle (90°) for edge-board mounting, and terminates via surface-mount solder tails.
Mechanical Retention and Board Fit
Three features lock this jack to the PCB: a board lock for SMT reflow retention, panel stops to set the correct height above the board, and solder retention pads that anchor the body against cable insertion and extraction forces.
