DF3A-2P-2DSA from Hirose Electric Co Ltd is a 2-position rectangular header in the DF3 series designed for compact board-to-board or cable interconnect applications. With a 2.00 mm pitch, male pin contacts, through-hole mounting, and push-pull fastening, it fits designs that need stable mechanical connection in space-conscious assemblies. Engineers commonly consider parts like this for consumer electronics, control boards, compact industrial equipment, and internal power or signal links where reliable mating and straightforward assembly are important. The connector uses brass contacts with tin finish, polyamide insulation, UL94 V-0 flammability material, and supports 3 A current rating with a -30°C to 85°C operating range. Lifecycle status is listed as unknown, so procurement teams should confirm current manufacturer support before locking it into long-term programs. REACH status is provided as unaffected, but RoHS compliance is not explicitly stated in the supplied data, so engineers should verify RoHS documentation directly from Hirose or authorized supply channels.
