The 3-338315-2 is a 25-position D-subminiature receptacle connector designed for vertical PCB mounting with integrated mating connector lock (female screwlocks, 4-40 UNC). It features a front metal shell (size 3) constructed from steel with a black polyester GF housing rated UL 94V-0 for flammability. The connector employs gold-plated contacts (30 µm) over phosphor bronze base material with tin plating on the shell, and includes grounding straps for enhanced signal integrity. With through-hole PCB mounting via boardlock retention, 3.20 mm termination post length, and tin-over-nickel solder tail plating, this connector is wave solder capable to 240°C, 260°C, and 265°C. It complies with DIN 41652 standards and is RoHS/ELV compliant, making it suitable for industrial control systems, data acquisition equipment, and legacy computing applications requiring reliable high-density interconnection.
