The contact uses a crimp termination — no soldering required — which means the wire is mechanically captured and the termination is repeatable with the correct crimp tool. The 20-24 AWG range covers the typical signal and low-current power wires used in D-sub applications: 24 AWG for multi-conductor signal cables, 20 AWG for higher-current circuits or longer cable runs. The stamped contact body is phosphor bronze, a spring-grade alloy that holds its shape under the crimp barrel compression and maintains contact force against the mating pin over temperature cycles. ## Gold plating thickness and mating cycle life The 30.0µin (0.76µm) gold finish on the contact area is a heavy plating grade for a stamped contact — standard commercial D-sub contacts often use flash gold (10-15 µinch) or selective plating. The gold is over the phosphor bronze base metal; no nickel underplate is specified in the listing, but the gold thickness alone indicates the contact is intended for reliable signal-level interconnects rather than high-current power duty.","metaTitle":"TE AMPLIMITE HDP-20 1658537-3, Stamped Socket Contact","metaDescription":"TE Connectivity AMPLIMITE HDP-20 stamped socket contact 1658537-3.

Availability and current pricing are confirmed at the time of quote — submit an RFQ for your target quantity and we will source it from the available channel."},{"question":"What housing is the 1658537-3 contact compatible with?","answer":"As an AMPLIMITE HDP-20 stamped socket contact, the 1658537-3 is designed for use with TE's standard D-subminiature housings that accept HDP-20 crimp contacts — this includes the full range of AMPLIMITE D-sub plug and receptacle shells. The contact is the socket (female) half, so it mates with the corresponding HDP-20 pin contact and inserts into the receptacle (female) housing."},{"question":"What is the wire gauge range for the 1658537-3?","answer":"The 1658537-3 accepts 20-24 AWG wire. This range covers typical signal wiring (24 AWG for multi-conductor cables) up to heavier-gauge power or ground wires (20 AWG) within the D-sub contact current rating."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/1658537-3","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/1658537-3 when reusing this data.
