The 5-87543-1: This is a 2-position, 2-row unshrouded header from the AMPMODU Mod II series, with a 2.54mm pitch and tin-plated male pins. It mates with standard 0.100-inch grid receptacles — typically AMPMODU Mod II socket housings or IDC connectors.
Dimensions for Board Layout
These dimensions set the board-to-board stack-up clearance and the through-hole drill depth — the 0.125" tail fits standard 0.062" to 0.093" thick PCBs with room for a proper solder fillet.
Contact and Housing Materials
The housing is glass-filled nylon (PA), UL94 V-0 rated for flame resistance.
