What This Jack Does in the Assembly
The TE Connectivity 2301995-4 is a single-port, shielded RJ45 jack built for 10/100/1000 Base-T and AutoMDIX applications. It terminates eight cores in one row, vertical orientation, and mounts through-hole with solder tails.
Shielding and Contact Finish for Signal Integrity
The brass shield and full shielding bleed common-mode noise to the chassis ground plane before it reaches the differential pairs — necessary for passing 1000 Base-T emissions limits.
LED Indicators and Visual Feedback
Three LED colors — green, yellow-green, and yellow — are integrated into the jack body. These give link/activity status at the port face without an external indicator board, saving a connector position on the PCB.
Sourcing and Fit Confirmation
The base product number is 2301995. Confirm the PCB footprint matches the vertical through-hole layout and the board lock hole pattern before committing the BOM line.
