The 5-103361-6: This is an 8-position, single-row, shrouded header from TE's AMPMODU Mod II series. It terminates through-hole and exits the board at a right angle, which means the mated cable runs parallel to the PCB — a common layout for board-edge I/O or low-profile enclosures where vertical clearance is tight. The 4-wall shroud protects the pins from accidental shorting during handling and guides the mating receptacle into alignment.
Gold on the mating face, tin on the tail
The post finish is tin at 100.0 µinch (2.54 µm), which solders cleanly into through-hole plated vias. Contact material is phosphor bronze, a standard spring alloy that holds its shape under the push-pull fastening force.
