A built-in board guide on the plug helps align the two halves during assembly, reducing shear stress on the SMT solder joints. The surface-mount termination suits automated pick-and-place lines, and the tube packaging feeds standard tray feeders. ## 0.80 mm Pitch vs 1.00 mm Peer — Footprint Density Trade-Off The 5179031-3's tighter 0.80 mm pitch saves board real estate — roughly 20% narrower per row — which matters when routing dense signal layers under the connector. The trade-off is that the finer pitch demands tighter PCB fab tolerances and narrower trace escapes between pads. Both parts are active and surface-mount, but the 1-120532-2 includes a pick-and-place feature and ships in a box rather than a tube. If your line handles tape-and-reel or box feeders, the 1-120532-2 may integrate more smoothly; for tube-fed lines, the 5179031-3 is the direct fit.","metaTitle":"TE Connectivity 5179031-3, Free Height (FH) 80-Pos Plug","metaDescription":"TE Connectivity 5179031-3 Free Height (FH) plug, 80 positions, 0.80mm pitch, SMT, gold contacts.
