DF3A-12P-2DS from Hirose Electric Co Ltd is a 12-position rectangular header in the DF3 series designed for board-to-board or cable interconnect applications where compact 2.00 mm pitch connectivity, secure mating, and dependable mechanical performance are important. Its right-angle through-hole format, shrouded 4-wall construction, and push-pull fastening style make it suitable for industrial controls, consumer electronics, embedded systems, power distribution modules, and general PCB interconnect designs. Engineers often choose parts in this category for stable signal and low-power current transfer, straightforward assembly, and durable use across broad operating temperatures. Based on the provided data, this connector supports 3 A current rating, uses UL94 V-0 insulation material, and operates from -55°C to 105°C, supporting use in demanding environments. Lifecycle status for DF3A-12P-2DS is currently listed as unknown, so design teams should confirm long-term availability directly with the manufacturer or authorized supply partners. RoHS compliance information is not explicitly provided here and should be verified through official documentation before release to regulated markets.
