The integral board guide aligns the plug during placement, protecting the fine-pitch contacts from shear damage during hand-load or reflow. ## Stack height flexibility — one plug, four board gaps A single 7-5177986-3 plug supports mated stacking heights of 7 mm, 11 mm, 15 mm, and 19 mm when paired with the matching Free Height receptacle. That range covers common mezzanine gaps from low-profile processor modules to taller add-in cards, letting one BOM line serve multiple board-spacing variants. The 0.270\" (6.85mm) height above board is the plug's own profile before mating — the final stack height depends on the receptacle half. No last-time-buy window or obsolescence notice. No direct functional equivalent from other manufacturers is documented in the series data. ## How it compares — 7-5177986-3 vs 1-120532-2 The 0.80 mm pitch of the 7-5177986-3 allows tighter board routing density, while the 1-120532-2's heavier gold supports a higher mating-cycle duty. The two are not footprint-compatible — the pitch difference alone prevents a direct swap on the same board layout.","metaTitle":"TE Connectivity 7-5177986-3 Free Height Plug, 80 Pos","metaDescription":"TE Connectivity Free Height (FH) plug, 80 positions, 0.80 mm pitch, gold-plated contacts, SMT.
