The 2-5177986-5 supports four mated stacking heights — 7 mm, 11 mm, 15 mm, and 19 mm — depending on the mating receptacle height. The plug itself sits 6.85 mm above the board. That height range covers common mezzanine spacing from tight card-to-card to wider board separation where airflow or component clearance matters. ## How does the contact finish affect the design? Gold plating at 8.00 µ\" on the mating surface resists corrosion in non-condensing environments.","metaTitle":"TE 2-5177986-5 Free Height Plug, 120 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity 2-5177986-5 Free Height (FH) plug, 120 positions, 0.80mm pitch, SMT, gold contacts.
