The TE Connectivity 1658543-2 is a stamped socket contact from the AMPLIMITE HDP-20 series, built for crimp termination onto 22-26 AWG wire. The 30.0µin gold plating on phosphor bronze gives it the cycle life for field-service D-sub connectors — above the 15 µ" threshold where tin starts fretting in low-level signal circuits. It mates with standard AMPLIMITE HDP-20 pin contacts in the matching housing.
Crimp termination means this socket is installed with a standard AMPLIMITE hand crimp tool — no solder iron needed. The 22-26 AWG range covers the common signal wire sizes for D-sub applications.
