This is a surface-mount plug with center strip contacts, gold-plated to 8.00µin on the mating surface. A built-in board guide on the connector body aligns the two halves during assembly, taking shear loads off the fine-pitch contacts before they engage. That matters at 0.80mm pitch — misalignment by half a pad pitch can short adjacent rows. ## Mated Stacking Heights and Board Spacing The 5179029-6 is rated for four mated stacking heights: 6mm, 10mm, 14mm, and 18mm. ## Comparing to the 1.00mm Pitch Sibling The closest peer in the Free Height family is the 1-120532-2, a 84-position plug at 0.039\" (1.00mm) pitch with 50.0µin gold plating. The 5179029-6 carries 140 positions versus 84, at a tighter 0.80mm pitch — so it fits more signals in the same board-edge length. The 1-120532-2's thicker gold (50.0µin vs 8.00µin) supports a higher mating cycle count for applications that see frequent board swaps. The 5179029-6 is the higher-density choice; the 1-120532-2 is the higher-durability choice if cycle life is the constraint. No official cross-reference or direct second-source is documented beyond the Free Height family itself.","metaTitle":"TE Connectivity 5179029-6 Free Height Plug, 140 Pos","metaDescription":"TE Connectivity 5179029-6 Free Height (FH) plug, 140 positions, 0.80mm pitch, SMT, gold contacts.
