Jack for 6p4c RJ11/RJ14 Lines
The TE Connectivity 215876-2 is a right-angle, through-hole modular jack wired for 6p4c (RJ11, RJ14) service. The 6p4c configuration means the connector body has six positions but only the centre four are populated with gold-plated phosphor bronze contacts — the outer two positions are left empty. This is the standard pinout for a single telephone line (RJ14) or a single-line RJ11 handset cord, where the tip and ring occupy the centre pair and a second pair sits on the adjacent positions. The jack is unshielded and carries a Cat3 rating, which covers voice and low-speed data (up to 16 MHz) typical of POTS and basic Ethernet-over-phone wiring.
Board Lock and Solder Termination
Through-hole solder tails take the mechanical load of repeated plug insertions, and the integrated board locks — two plastic posts that snap into the PCB — hold the connector flat during wave soldering and resist the shear force when a cable is yanked. The housing is polybutylene terephthalate (PBT), a common choice for its dimensional stability through the solder cycle.
