It uses a dual-row, 0.020\" (0.50mm) pitch layout with center strip contacts, all gold-plated to 10.0µin (0.25µm). The connector is surface-mount and includes a board guide for alignment during pick-and-place, plus solder retention pads to anchor the part through reflow and resist shear forces from the mated header. It supports two mated stacking heights — 3mm and 5mm — by pairing with the corresponding Fine Mate header. The 80 circuits at this pitch suit high-density signal routing where board real estate is tight, such as in compact handheld devices or module stacking. ## What the 0.50 mm Pitch and 80 Positions Mean for Your Board The 0.50 mm pitch is the tightest common mezzanine pitch; it drives the board layout density and rules out hand-soldering — this is a reflow-only part. The 80 positions in a dual-row configuration give a narrow overall width, which helps with routing channels in a dense mezzanine stack. The board guide and solder retention features are practical for automated assembly — the guide helps the nozzle place the part accurately, and the retention pads keep the connector from lifting during reflow or under cable strain from the mated header.","metaTitle":"TE Connectivity 8-2041251-0 Fine Mate Receptacle, 80 Pos","metaDescription":"TE Connectivity 8-2041251-0 Fine Mate receptacle, 80 positions, 0.50mm pitch, dual-row, SMT.
