Phosphor bronze base material provides spring retention in the housing cavity. ## Wire sizing and termination The 24-28 AWG range covers the common signal-wire sizes for D-sub harnesses — 24 AWG for longer runs or higher current, 28 AWG for dense multi-conductor cables. The crimp termination requires the matching TE hand tool or pneumatic applicator; the stamped contact design gives consistent strip-and-crimp results across the wire range. Active lifecycle — no end-of-life notice on record. No official cross-reference or second-source part is listed for this exact contact.","metaTitle":"TE Connectivity 66683-4 AMPLIMITE HDP-20 Socket Contact","metaDescription":"TE Connectivity 66683-4 stamped socket contact for AMPLIMITE HDP-20 D-sub connectors. 24-28 AWG, gold plating 30.0µin, crimp termination.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Circular Connectors","Multi-Purpose Circular"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Type":"Stamped","Series":"AMPLIMITE HDP-20","Package":"Bulk","Wire Gauge":"24-28 AWG","Pin or Socket":"Socket","Contact Finish":"Gold","Product Status":"Active","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Base Product Number":"66683","Contact Termination":"Crimp","Contact Finish Thickness":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4900","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/0146937f99f654e8d553ff7b5ad7d320.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What wire gauge does the 66683-4 socket contact accept?","answer":"The 66683-4 accepts 24-28 AWG wire.
