With a 0.016\" (0.40mm) pitch and dual-row layout, it packs 120 circuits into a compact footprint suited for dense PCB stacking in portable electronics, handheld devices, and camera modules. The connector is a receptacle with center strip contacts, designed to mate with the matching DF40 series header for a mated stack height of 1.5mm — the z-height budget for the board gap is fixed by this dimension, so the header and receptacle pair must be specified together to hit that 1.5mm target. ## Surface-Mount Termination and Gold Flash Contacts Termination is surface mount, with the contacts finished in gold. The 0.40mm pitch leaves minimal room for routing escape traces between pads; a four-layer or higher board stack-up with microvias is typical to route all 120 signals out of the connector footprint. ## Position Count Comparison in the DF40C Subseries The 120-position variant carries 20 more circuits than the DF40C-100DS-0.4V(51) at the same 0.40mm pitch and 1.5mm stack height, and 40 more than the DF40C-80DS-0.4V(51). The contact finish thickness on the 120-position part is 1.97µin (0.050µm), slightly thinner than the 2.00µin (0.051µm) on the 100-, 90-, and 80-position siblings — a negligible difference for signal-level duty but worth noting if the application requires a high number of mating cycles across the full population of positions. No last-time-buy or end-of-life notices are on record for this order code.","metaTitle":"Hirose DF40C-120DS-0.4V(51) Receptacle, 120 pos","metaDescription":"Hirose DF40C-120DS-0.4V(51) receptacle, 120 positions, 0.40mm pitch, 1.5mm stack height, gold contacts, SMT.
