The surface-mount termination keeps the profile low, and the integral board guide aligns the plug during assembly to protect the fine-pitch solder joints. ## Stack Height Options and PCB Layout Fit This plug supports four mated stacking heights — 6mm, 10mm, 14mm, and 18mm — by pairing with the corresponding Free Height receptacle. The 0.80mm pitch demands tight routing discipline: trace widths and clearances on inner layers need to match the 0.80mm grid to avoid crosstalk in high-speed designs. The closest functional peer in the same family is the 1-120532-2, an 84-position plug on a wider 1.00mm pitch with 50.0µin gold plating. The 5179029-4 carries 16 more positions in a denser footprint (0.80mm vs 1.00mm), which shrinks the board real estate per circuit but demands tighter PCB routing. The 1-120532-2's heavier gold is better suited for applications requiring more than 100 mating cycles; the 5179029-4's 8.00µin gold is adequate for moderate-cycle backplane or mezzanine duty. The two are not footprint-compatible — pitch and position count differ — so they are not direct alternates without a layout change.","metaTitle":"TE 5179029-4 Free Height (FH) Plug, 100 Pos, 0.80mm Pitch","metaDescription":"TE Connectivity 5179029-4 Free Height (FH) plug, 100 positions, 0.80mm pitch, gold-plated center strip contacts, SMT.
