The TE Connectivity 1909119-4 is a right-angle through-hole modular jack with a USB A connector integrated into the same housing — an unusual dual-function part that carries both an 8p8c (RJ45, Ethernet) port and a USB A port in a single board-edge footprint. It sits in the 1909119 base series, which covers multi-port and combo jacks for panel-mount and PCB applications. The glass-filled PBT housing provides the dimensional stability and flame resistance expected for equipment inside an enclosure.
Board Lock and Orientation — What They Mean for Assembly
The board lock feature is a pair of solderable retention posts that anchor the jack to the PCB during wave soldering and resist the shear force from repeated cable insertion and removal. Without them, the through-hole solder joints alone would fatigue over time in a high-cycle application. The tab direction is up, meaning the RJ45 latch release is on the top side, accessible from above the board.
The bulk packaging means the part ships loose in a bag or tube, not on tape-and-reel, so factor that into your assembly line feed method.
