The TE Connectivity 5555163-5 is a 6p2c (RJ11) modular jack, right-angle orientation for board-edge mounting. It sits in the standard TE modular jack family, defined by the base number 5555163. This is the unshielded variant with gold-plated contacts, designed for voice and low-speed data terminations where Cat3 performance is sufficient — think analog phone lines, PBX extensions, or legacy modem connections in telecom equipment and building entry panels.
Pinout and Wiring — What You Get with 6p2c
6p2c means six positions in the connector body, with only the centre two positions populated with contacts. That gives you a single pair — tip and ring — for one analog line.
The board lock feature — two integral plastic posts that snap into plated-through holes — anchors the jack during wave solder and resists the plug insertion/extraction forces that would otherwise stress the solder joints. Panel stops on the housing set the insertion depth against the panel cutout, giving a consistent front-panel fit without shims.
