The 0.80mm pitch drives a compact board footprint — each row of 40 contacts fits in a narrow keep-out zone, which is typical for high-density mezzanine links in telecom line cards or server blades. The four available mated stacking heights (5mm, 6mm, 7mm, 8mm) let the designer tune the gap between the two PCBs without changing the receptacle or the plug footprint; the same board layout works across all four heights by swapping the plug height. The surface-mount termination and built-in board guide aid alignment during reflow assembly.","metaTitle":"TE Connectivity 5177985-3 Free Height (FH) Receptacle","metaDescription":"TE Connectivity 5177985-3 Free Height (FH) receptacle, 80 positions, 0.80mm pitch, gold-plated contacts.
