DF37C-50DP-0.4V(53) from Hirose Electric Co Ltd is a surface-mount rectangular connector header in the DF37 family, designed for compact, fine-pitch board-to-board interconnect needs in space-constrained electronics. With a 50-position configuration, outer shroud construction, and gold contacts, it fits applications such as industrial control boards, portable devices, embedded modules, display assemblies, and other densely packed electronic systems where reliable signal interconnection is important. As a Hirose connector, it is positioned for designers seeking a recognized interconnect brand with established use in compact electronic assemblies. From a sourcing perspective, the listed supply and demand status is limited and estimated production lead time is 25 weeks, so procurement planning is advisable for ongoing builds. Lifecycle status is currently information not available, so engineers should confirm long-term availability with the manufacturer. RoHS compliance information is also not explicitly provided in the supplied specifications, and official documentation should be checked before regulated-market deployment.
