DF37C-30DP-0.4V(53) from Hirose Electric Co Ltd is a fine-pitch rectangular connector header designed for compact board-to-board interconnect applications where space, profile, and reliable signal routing are critical. With a 0.40 mm pitch, 30 positions, dual-row layout, and SMT mounting, it is well suited for portable electronics, industrial control modules, communication devices, embedded assemblies, and other high-density PCB designs. The gold contact finish supports dependable mating performance in precision electronic systems. Based on the provided status, this part is listed as Active, which is favorable for ongoing design consideration, although engineers should still confirm long-term availability directly with the manufacturer or authorized distribution sources. RoHS compliance information is not explicitly provided in the supplied specifications, so compliance status should be treated as information not available pending official datasheet or manufacturer confirmation. For procurement teams, balanced supply-demand status and reel packaging make it relevant for volume assembly planning.
