DF3A-4P-2DS from Hirose Electric Co Ltd is a rectangular connector header designed for compact board-to-wire or board-level interconnect applications where dependable mechanical fit and straightforward assembly are important. As a through-hole, right-angle, 4-position connector in the DF3 family, it is well suited for industrial controls, consumer electronics, embedded systems, power distribution subassemblies, and space-constrained PCB layouts that need a 2.00 mm pitch interface. Engineers typically choose parts in this category for stable mating performance, serviceability, and broad use across long-life equipment platforms. The provided operating temperature range of -55°C to 105°C supports use in demanding environments beyond basic commercial conditions. Lifecycle status for this part is listed as unknown, so design teams should confirm current manufacturer status before locking it into new programs. RoHS compliance information is not explicitly provided in the supplied specifications; engineers should verify the latest compliance declaration and datasheet directly with Hirose Electric Co Ltd or an authorized source.
