The TE Connectivity 5-2301995-2 is a single-port, shielded RJ45 jack built for 10/100 Base-T Ethernet with AutoMDIX support. It carries four cores per jack — the standard pinout for 10/100 twisted-pair — and terminates to the PCB through a through-hole solder connection. The vertical orientation means the cable plugs in perpendicular to the board, which suits panel-mount or edge-located ports where the connector body sits above the board at 0.665" (16.90 mm). This is a straight-ahead Fast Ethernet jack: no PoE rating, no Gigabit bandwidth spec, no magnetics integrated. It's the connector half you drop into a 10/100 port design where the magnetics are handled elsewhere on the board or in the cable-side dongle. The AutoMDIX support means it handles crossover detection at the PHY level — no crossover cable needed.
Shielding and Contact Finish — What Matters for the Connection
The shell is shielded and made from brass, which gives decent EMI attenuation for a factory-floor or telecom-closet environment. The board lock feature — a pair of through-hole retention posts — anchors the jack against the insertion and withdrawal force of a standard RJ45 plug, so the solder joints don't take the mechanical load over repeated mates. Tin-plated jacks wear through faster under repeated mating; the gold here keeps contact resistance stable across those cycles.
Temperature Range and Housing
The liquid crystal polymer holds its dimensional stability through wave solder and doesn't wick moisture the way nylon can. No LED indicator on this variant — if you need link/activity lights on the port, this isn't the version for that.
