Gold-plated center strip contacts (8.00µin / 0.203µm) handle moderate mating cycle counts typical of production test and field-service swaps, though the thin plating won't match the cycle life of a 30µin or 50µin gold option. ## Stack Height Options and Mating Half The 0.230\" (5.85mm) height above board of the plug itself is the un-mated profile; the final stack height depends on the receptacle height chosen. Surface-mount termination (SMT) suits automated pick-and-place assembly, and the Tape & Reel packaging feeds directly into the line without a tray changeover. ## Sourcing and Lifecycle Reality The base product number 5177986 ties to the full Free Height family, so mating receptacles and alternate position counts share the same footprint geometry. The 1-120532-2 is a different Free Height variant at 1.00mm pitch with 84 positions — a looser pitch that eases trace routing but carries fewer circuits. The 1-5177986-6 at 0.80mm pitch packs 140 positions into roughly the same board edge length, so the decision between them is density vs routing layer count. The 1-120532-2 also carries 50.0µin gold plating against the 8.00µin on this part, making it the better choice for applications requiring higher mating cycle durability.","metaTitle":"TE 1-5177986-6 Free Height Plug, 140 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity 1-5177986-6 Free Height (FH) plug, 140 positions, 0.80mm pitch, gold contacts, SMT.
