DF40HC(2.5)-60DS-0.4V(51) from Hirose Electric Co Ltd is a surface-mount rectangular connector receptacle in the DF40 family, designed for compact board-to-board interconnect applications where space efficiency and reliable signal transfer are critical. With 60 positions, center strip contacts, gold plating, and tape-and-reel packaging, it is well suited for high-density consumer electronics, portable industrial devices, embedded control boards, display modules, and communication hardware. Engineers typically select parts in this connector class for fine-pitch interconnects that support slim product architectures and repeatable assembly in automated SMT production. Lifecycle status is listed as unknown, while the supply and demand status is limited and estimated production lead time is 25 weeks, so procurement teams should plan carefully for ongoing builds. RoHS compliance information is not explicitly provided in the supplied specifications; engineers and compliance teams should verify current RoHS and REACH status directly through the official datasheet or manufacturer documentation before release to regulated markets.
