DF37NB-24DS-0.4V(75) from Hirose Electric Co Ltd is a fine-pitch rectangular receptacle connector designed for compact board-to-board interconnect applications where space, profile, and assembly reliability matter. With a 0.40 mm pitch, 24 positions, dual-row format, and SMT mounting, it is well suited for portable electronics, industrial modules, embedded control boards, display assemblies, and other high-density designs that require low stacking height. Gold contact finish and solder retention features support stable electrical contact and dependable SMT processing. Based on the provided status, this part is Active, which is generally favorable for ongoing production and maintenance planning, although engineers should still confirm long-term availability with current manufacturer and channel data. RoHS compliance information is not explicitly provided in the supplied specifications, so compliance status should be treated as information not available until verified through Hirose documentation or an authorized source. For procurement teams, balanced supply-demand and high market popularity suggest this is a practical, commonly used connector to monitor closely.
