DF36A-30S-0.4V(52) from Hirose Electric Co Ltd is a fine-pitch 30-position receptacle designed for board-to-cable/wire interconnection in compact electronic assemblies. Built in the DF36 series, it uses a 0.40 mm mating pitch, SMT mounting, solder termination, friction lock retention, and gold-plated phosphor bronze contacts, making it suitable for space-constrained consumer, industrial, and embedded device designs where reliable signal connection and assembly efficiency matter. The LCP halogen-free housing and UL94 V-0 flammability rating support use in products that require modern material compliance considerations, while the -35°C to 85°C operating range fits many general-purpose electronics environments. Lifecycle status is currently listed as unknown, so engineers should confirm long-term availability directly with the manufacturer or authorized sources before locking it into new programs. Formal RoHS status is not explicitly provided in the supplied data; based on material details it may align with common RoHS-oriented design practices, but official compliance documentation should be verified before qualification.
