The TE Connectivity 5556416-1 is a vertical through-hole modular jack, wired 8p8c for standard RJ45 Ethernet connections. The tab direction is user-selectable, a practical detail when the jack sits behind a panel or enclosure cutout that has a specific latch orientation.
The 8p8c (RJ45) wiring scheme accepts a standard 8-position modular plug with the T568A or T568B pinout. The 50.0µin gold on the contacts is a heavy deposit that resists corrosion and fretting in environments where the cable gets reconnected regularly. Being unshielded, the jack does not provide its own EMI gasket — the system ground path must be handled at the PCB or chassis level if the application runs in a high-noise environment.
Vertical orientation and through-hole solder termination. Single-row, single-port design. The user-selectable tab direction lets the latch face either up or down relative to the PCB edge — a mechanical fit detail that matters when the jack is mounted near a panel lip or in a recessed cutout.
