The TE Connectivity 5569984-1 is a vertical unshielded modular jack with 6 positions and 6 contacts (6p6c), compatible with RJ11, RJ12, RJ14, and RJ25 plug configurations. It sits in the standard TE modular jack family, identified by the base product number 5569984. The jack is through-hole mounted for soldered board attachment, with a vertical orientation that places the plug entry perpendicular to the PCB — a common layout for wall-plate or panel-mount applications where the cable enters from above. The unshielded plastic housing suits environments where EMI shielding is handled at the system level rather than the connector. Rated Cat3, this jack is specified for voice and low-speed data links up to 16 MHz — the standard for telephone lines, PBX systems, and legacy 10BASE-T Ethernet. The 6p6C contact arrangement gives you six conductors in a single row, which covers two-line phone with a centre tap or basic RS-232 signalling over modular cable.
The vertical through-hole footprint is straightforward for a standard 6-position modular jack. Without the board lock, the solder joints alone would bear the shear force from repeated cable movements, which can crack the fillets over time. Single-row, single-port design keeps the board footprint compact. The tab direction is user-selectable, meaning the latch tab on the mating plug can face either way — a detail that matters when routing the cable in a tight enclosure. No LED means no additional soldering or light-pipe routing; this is a straight pass-through jack for signal only.
