DF3A-5P-2DSA from Hirose Electric Co Ltd is a 5-position DF3 series connector header used in compact board-to-board or cable interconnect designs where secure mating, 2.00 mm pitch density, and dependable mechanical alignment are important. With a shrouded 4-wall housing, push-pull fastening, through-hole mounting, and support for press-fit or solder termination, it fits embedded control boards, industrial equipment, consumer electronics, and power/control harness interfaces. Its 3 A current rating, UL94 V-0 polyamide insulation, and -55°C to 105°C operating range make it suitable for demanding environments that require stable electrical and thermal performance. Lifecycle status is currently listed as information not available, so design teams should confirm long-term availability directly with Hirose or an authorized source before committing to new production. RoHS compliance status is also not explicitly provided in the supplied data; engineers should verify the latest manufacturer documentation for RoHS and REACH declarations before regulated-market deployment.
