15-Position D-Sub Receptacle with Press-Fit Termination
The TE Connectivity AMPLIMITE HD-20 5786144-1 is a 15-position D-Sub receptacle with female sockets arranged in two rows. It uses press-fit termination — the compliant pin compresses into the plated through-hole without solder, which keeps the assembly lead-free and simplifies rework on the backplane or I/O card. The shell size is DA (A), the standard layout for 15-pin D-Subs, so the panel cutout and mating plug are predictable. The steel shell with tin plating provides EMI shielding and mates with the standard D-Sub grounding indents.
Press-Fit Assembly and the Screwlock Flange
Press-fit termination means no solder wave — the compliant pin displaces the barrel wall for a gas-tight joint. That saves a process step on the line but requires a controlled insertion force and a backplane thick enough to hold the pin in tension. The flange carries female screwlocks on the mating side (4-40 thread) — they accept the jackscrews from the plug side and lock the pair together against vibration. In a high-shock environment like a rail or off-highway cab, those screwlocks are what keep the I/O from walking loose.
Position Count and Compatibility Across AMPLIMITE HD-20
At 15 positions, this receptacle matches the DA shell size — the same footprint as any standard 15-pin D-Sub. The AMPLIMITE HD-20 series also offers 9-position (DE) and 25-position (DB) variants in the same press-fit and gold-plating configuration. The 15-position count is the middle ground: more I/O than a 9-pin serial port, less than a 25-pin parallel interface. The 5786144-1 mates with any standard 15-pin D-Sub plug that carries the 4-40 jackscrew hardware.
