25-Pin DB-25 Receptacle for Standard-Density D-Sub Applications
The TE Connectivity 5745078-6 is a 25-position D-Sub receptacle from the AMPLIMITE HD-20 series, configured as a vertical through-hole solder mount with 2 rows of female sockets. The shell size is DB (B), meaning the 25-pin layout follows the standard DB-25 footprint — the same pattern used on serial ports and industrial I/O panels for decades. The 6A per contact rating at 125V is typical for standard-density D-Sub connectors; the limiting factor here is the pin density at the board edge, not the contact itself. The mating-side female screwlock with 4-40 threads accepts standard male jackscrews — a detail that matters when the connector lives in a vibration environment where the screwlock keeps the pair mated.
The 6A per contact rating at 125V is the standard current envelope for a DB-25 density D-Sub. For signal-level applications — RS-232, parallel I/O, sensor inputs — this is generous headroom.
The termination is through-hole solder: the pins are 0.040-inch square posts on 0.108-inch row spacing, fitting a standard 0.125-inch PCB hole pattern. The flange has female screwlock threads (4-40) on the mating side, which means the male plug needs the corresponding male jackscrew hardware to lock the pair together. No crimp or IDC termination here — this is a solder-to-board part.
