DF37C-24DP-0.4V(53) from Hirose Electric Co Ltd is a fine-pitch rectangular board-to-board connector designed for compact electronic assemblies where space, profile, and signal density matter. As a 24-position, 2-row SMT header with a 0.40 mm pitch and low 0.75 mm height above board, it is well suited for slim portable devices, industrial control modules, embedded computing boards, and other high-density interconnect designs. Engineers typically choose this series when they need reliable mating performance in tightly stacked PCB architectures while maintaining manufacturability in reel packaging for automated assembly. Based on the provided data, the part status is Active, which is favorable for ongoing procurement, although lifecycle should still be verified against current manufacturer notices for long-term programs. RoHS compliance information is not explicitly provided in the supplied specifications, so compliance status should be treated as information not available until confirmed through the official Hirose datasheet, declaration, or authorized distribution documentation.
