25-Position D-Sub Receptacle with Board Lock
The TE Connectivity AMPLIMITE HDP-20 3-338315-2 is a 25-position D-Sub receptacle with female sockets arranged in two rows. It uses the standard DB-9 shell layout (3, DB, B), meaning the panel cutout and footprint match the familiar 25-pin D-sub pattern. The 6A per-contact rating with gold-plated phosphor bronze contacts suits signal-level interconnects in equipment that sees repeated mating cycles — the gold finish, not the current, is the limiting factor for the duty.
What the 6A and Gold Contacts Mean for the Fit
At 6A per contact, this receptacle is sized for signal and low-power circuits, not a main DC rail.
The steel shell with tin plating provides EMI shielding when mated with a conductive backshell. The mating side carries a 4-40 female screwlock — pair it with the matching male screwlock on the plug side to keep the pair mated under vibration.
