The 100 positions in two rows means 50 contacts per row, which requires a dense fan-out strategy on the bottom board. The four supported mated stacking heights (6mm, 10mm, 14mm, 18mm) are set by the mating receptacle height, not the plug itself, so the plug's SMT footprint stays constant across all stack height options.","metaTitle":"TE 1-5177986-4 Free Height Plug, 100 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity 1-5177986-4 Free Height (FH) plug, 100 positions, 0.80mm pitch, SMT, gold contacts.
