Typical use is stacking parallel PCBs at mated heights between 5 mm and 8 mm, common in compact telecom, networking, and server modules where signal density and board spacing are both constrained. ## 0.80 mm Pitch and Stack Height Range The 0.80 mm pitch is the tightest standard in the Free Height family — the sibling 1-120532-2 runs at 1.00 mm pitch and carries 84 positions in a plug form factor. For the 5177985-1, the 40 positions at 0.80 mm pitch give a compact board footprint that still leaves room for two signal traces between pads on a typical PCB. Confirm the plug's stack height code against your board spacing before ordering. This is a standard-duty plating grade — adequate for the moderate mating cycle counts typical of production board stacking and field replacement, but not specced for high-cycle hot-swap or corrosive environments. The gold layer prevents oxidation on the contact interface during the shelf life of unassembled boards. No official cross-reference or second-source is on record; the 1-120532-2 is a different pitch and position count and is not a functional substitute. Stock both halves of the mating pair when you order — the receptacle alone is an orphan without its FH plug.","metaTitle":"TE 5177985-1 Free Height (FH) Receptacle, 40 Pos","metaDescription":"TE 5177985-1 Free Height (FH) receptacle, 40 positions, 0.80mm pitch, SMT, gold plating.
