The plug is surface-mount, with a board guide feature to self-align during reflow assembly, reducing placement errors on automated lines. ## Stack Height Versatility This plug supports four mated stacking heights: 6mm, 10mm, 14mm, and 18mm. That means the same 100-position plug can be paired with the matching FH receptacle to span different board-spacing requirements — from a tight 6mm sandwich to an 18mm gap for component clearance on the underside. That gold layer is the key to repeated mating cycles — it resists oxidation and fretting corrosion better than tin, so this plug holds up in equipment that gets reconnected during service or testing. For a 100-position mezzanine connector, the gold thickness directly governs how many board-stack/unstack cycles the interface can tolerate before contact resistance drifts. The 6-5177986-4 has an active lifecycle status with RoHS compliance. No last-time-buy notice on record — standard sourcing through distribution. For BOM planning, the pitch and position count are the critical fit parameters to verify against the mating receptacle and board layout.","metaTitle":"TE 6-5177986-4 Free Height Plug, 100 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity Free Height (FH) plug, 100 positions, 0.031\" (0.80mm) pitch, SMT, gold 30.0µin.
