DF3A-3P-2DSA from Hirose Electric Co Ltd is a 3-position DF3 series header used in compact board-to-board or cable interconnect designs where secure mating, consistent signal transfer, and space efficiency are important. With a 2.00 mm pitch, male pin contacts, through-hole mounting, and push-pull fastening, it fits embedded electronics, industrial controls, consumer devices, and internal power/signal harnessing applications. The housing uses black polyamide (PA, nylon) insulation with UL94 V-0 flammability rating, while tin-finished brass contacts support practical assembly and general-purpose connectivity needs. Its 3 A current rating and operating range of -55°C to 105°C make it suitable for designs exposed to wider environmental variation. Lifecycle status is listed as unknown, so long-term programs should confirm manufacturer guidance before release to production. RoHS compliance information is not explicitly provided in the supplied specifications, so engineers and compliance teams should verify current RoHS and REACH status using the official datasheet or manufacturer documentation.
