DB-25 Plug for Panel-Mount Signal Harnesses
The TE Connectivity 5745073-1 is a 25-position D-sub plug from the AMPLIMITE HD-20 series, built for vertical through-hole solder termination to a PCB. It carries the standard DB-25 shell layout (shell size 3, DB, B), meaning it fits the same panel cutout and mates with any standard DB-25 receptacle.
Rated for Signal-Duty Power and Isolation
Each contact is rated 6A at 125V. For a mixed-signal harness carrying a few amps on power pins and milliamps on signal lines, this plug handles the duty without derating at room temperature.
Mating Hardware and Panel Fit
The flange carries female screwlocks on the mating side with standard 4-40 thread. This is the common D-sub jack-screw size — a male screwlock on the mating receptacle or a 4-40 hex standoff secures the pair. The shell size DB-25 means the mounting hole centres are 1.213 inches (30.81 mm) apart, the standard footprint for a DB-25 panel cutout. Mates with any standard DB-25 receptacle housing, including the TE AMPLIMITE HD-20 receptacle series.
The 8-1437045-3 is another active sibling in Bulk packaging.
