DF3A-10P-2DSA from Hirose Electric Co Ltd is a 10-position rectangular header designed for compact board-to-board or cable interconnect applications where secure mating, reliable current handling, and durable mechanical performance are important. As part of the DF3A family, it uses a 2.00 mm pitch, shrouded 4-wall construction, and push-pull fastening to support dependable connection in space-conscious electronic assemblies. Engineers may consider this part for industrial controls, consumer electronics, embedded systems, power distribution subassemblies, and general-purpose PCB interconnect designs requiring through-hole mounting and up to 3 A current rating. The material set, including brass contacts, tin finish, UL94 V-0 housing, and an operating range of -55°C to 105°C, suggests suitability for demanding environments. RoHS status is provided as RoHS Compliant, which supports use in environmentally regulated markets. Lifecycle status is currently listed as unknown, so design teams should confirm the latest manufacturer status and long-term availability before committing it to new programs.
