{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"316229-3","brand":"TE Connectivity AMP Connectors","brandSlug":"te-connectivity-amp-connectors","productSlug":"316229-3","canonicalUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/316229-3","factsUrl":"https://icsourcedirect.com/api/mcp/products/316229-3","rawCanonicalId":null},"summary":{"shortDescription":"TE Connectivity Free Height (FH) series, Plug Center Strip Contacts, 80 positions, 2 rows, 0.031\" (0.80mm) pitch, Surface Mount Right Angle, Gold 11.8µin (0.30µm) contact finish, 0.201\" (5.10mm) height above board.","salesMarkdown":"## 80-Position Mezzanine Plug at 0.80mm Pitch The 0.031\" (0.80mm) pitch packs 80 circuits into a dual-row layout, and the 0.201\" (5.10mm) height above board sets the mated stack height — critical when you're budgeting z-space between mezzanine boards. This is a plug with center strip contacts, right-angle SMT mount, meant to mate with the matching Free Height receptacle on the opposing board. ## Pitch, Position Count, and the Board Footprint The 0.80mm pitch is the tightest in the Free Height series — compare it to the sibling 1-120532-2, which runs 84 positions at a wider 0.039\" (1.00mm) pitch and a taller 0.250\" (6.35mm) stack height. That extra pitch buys you more routing channels between pads, but the 316229-3's 0.80mm pitch is the right call when the board real estate is the constraint. Both are dual-row plugs, but the 316229-3 carries a board guide to keep the alignment during reflow — the 1-120532-2 substitutes a pick-and-place feature instead. The 316229-3's gold thickness is 11.8µin (0.30µm) versus the 50.0µin (1.27µm) on the 1-120532-2; the thicker gold on the sibling buys more mating cycles if your application cycles boards frequently, but for a typical mezzanine stack that mates once in production, the 316229-3's gold is adequate. ## Board Layout and Assembly Considerations The board guide is not cosmetic — it prevents the part from skewing during reflow, which matters when you have 80 solder joints at 0.80mm pitch. No press-fit or through-hole here; this is a reflow-only part, so your stencil aperture and paste volume need to match the fine-pitch footprint. The package is Tube, so plan for tube-fed pick-and-place or manual placement for prototypes.","metaTitle":"TE Connectivity 316229-3 Free Height Plug, 80 Pos","metaDescription":"TE Connectivity 316229-3 Free Height (FH) plug, 80 positions, 0.80mm pitch, right-angle SMT, gold contacts.
