Pitch, Stack Height, and Routing Constraints
The 77311-104-36LF: At 0.100" pitch, the board footprint matches a 36-pin through-hole pattern with 0.100" row spacing. Unshrouded design means no side walls to guide the mating half; the pins take the alignment load. For dense board layouts, the keep-out zone is just the pin footprint plus a small clearance for solder fillets.
