DF37C-10DP-0.4V(75) from Hirose Electric Co Ltd is a compact board-to-board rectangular connector designed for high-density electronic assemblies where space, height, and signal integrity matter. As a 10-position, 0.40 mm pitch mezzanine-style header with SMT mounting and gold-plated contacts, it is well suited for portable devices, embedded control boards, industrial modules, compact consumer electronics, and other stacked PCB designs requiring reliable interconnect performance in a low-profile form factor. Engineers typically choose parts in the DF37 series when they need fine-pitch connection in constrained layouts without sacrificing manufacturability in tape-and-reel assembly flows. Lifecycle status for this part is currently listed as unknown, so teams should confirm long-term availability directly with the manufacturer or authorized supply channels before locking it into new designs. RoHS compliance information is not explicitly provided in the supplied specifications; therefore, compliance should be treated as information not available pending verification through official Hirose documentation or manufacturer declaration.
