2-Port Shielded RJ45 for Gigabit Ethernet
The TE Connectivity 5-2301996-4 is a 2-port RJ45 jack rated for 10/100/1000 Base-T with AutoMDIX support — meaning it handles Gigabit Ethernet traffic and auto-corrects for straight-through vs crossover cables at the physical layer. Each of the two ports carries 8 cores, standard for 8P8C Ethernet jacks.
Shielding and Board Retention
This jack is shielded with an EMI finger and a brass shield body. The EMI finger contacts the panel cutout or chassis ground before the signal pins engage — that bleed path keeps common-mode noise off the Ethernet transformer side. For a design chasing FCC Class B or EN 55022, that grounded shield is the difference between passing and a re-spin. The board lock feature (two through-hole retention posts) anchors the jack during wave solder and resists the lever force from a stiff Cat6 cable pulling sideways at the faceplate.
Through-hole solder termination, right-angle orientation with tab facing down. The 0.531" (13.49 mm) height above board is the z-space the jack occupies above the PCB — check that clearance against the enclosure lid or card-guide above the board. The tab-down orientation means the latch release is on the bottom side, typical for horizontal PCB mounting where the cable exits downward.
