The TE Connectivity AMPLIMITE HDF-20 1658613-3 is a 15-position D-sub plug with male pins, designed for IDC termination to 26-28 AWG stranded or solid ribbon cable. It sits in the standard DA (A) shell size — the 15-pin layout that matches the common DB-15 footprint.
Termination and Cable Prep — What the IDC Means for Your Build
This is an IDC (insulation displacement) connector, not a crimp or solder type. It accepts 26-28 AWG stranded or solid wire — the narrower range than a typical IDC connector (many take 24-28 AWG) means the cable spec is locked: if your harness uses 24 AWG ribbon, this part won't terminate reliably. The steel shell with tin plating and the grounding indents provide a continuous shield path from the cable braid through the connector body to the mating receptacle shell.
Contact Metallurgy and Duty Cycle
Gold-plated phosphor bronze contacts. Phosphor bronze as the base spring material holds contact force after years of thermal cycling. For a 15-position fully loaded connector, that's 18.75 A total across the interface, but the derating curve (not published here) will pull that down above 85°C ambient.
