DF36A-15S-0.4V(51) from Hirose Electric Co Ltd is a fine-pitch 15-position receptacle designed for compact board-to-cable or wire interconnect applications where space savings and reliable SMT assembly are critical. Built in the DF36 series, it uses a friction-lock structure, gold-plated phosphor bronze contacts, and an LCP halogen-free housing with UL94 V-0 flammability performance, making it suitable for densely packed portable, industrial, and embedded electronic designs. Engineers typically consider this style of connector for compact control boards, handheld devices, miniature modules, and other systems that need stable low-voltage interconnection in a small footprint. The listed lifecycle status is unknown, so design teams should confirm current production status directly with Hirose or an authorized source before locking it into new programs. RoHS compliance information is not explicitly provided in the supplied specifications; however, the halogen-free material callout may support environmentally conscious designs. Official manufacturer documentation should be checked for RoHS and REACH confirmation.
