Black housing, bulk packaging. ## Why the 3.50mm Pitch Matters for Your Harness At 3.50mm pitch, this receptacle is sized for power distribution or larger-gauge signal wiring — wider than a typical signal header (2.54mm), giving more room for insulation and crimp barrels. The single-row, 2-position layout keeps the connector compact for point-to-point or daisy-chain runs where only a pair of wires is needed. Crimp termination means you'll need the correct female socket terminal (sold separately) and a hand or auto-crimp tool. The housing includes a Terminal Position Lock (TPA) notch — a secondary lock that confirms the terminal is fully seated and prevents back-out under vibration.","metaTitle":"Molex Ultra-Fit 1722561102 Receptacle, 2-Pos, 3.50mm","metaDescription":"Molex 1722561102 Ultra-Fit receptacle, 2 circuits, 3.50mm pitch, single row, latch lock, crimp termination, contacts not included.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Wire-to-Board Connectors"],"specifications":{"Mfr":"Molex","Note":"Contacts Not Included","Color":"Black","Pitch":"0.138\\\" (3.50mm)","Series":"Ultra-Fit 172256","Package":"Bulk","Features":"Terminal Position Lock (TPA) Notched","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Fastening Type":"Latch Lock","Number of Rows":"1","Product Status":"Obsolete","lifecycle_stage":"unknown","Base Product Number":"172256","Contact Termination":"Crimp","Number of Positions":"2"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/03f667d12305405689126efbfc2dbc73.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1722561102/alternatives.json"},"ai":{"faq":[{"question":"Is 1722561102 obsolete?","answer":"Yes, the manufacturer lists the 1722561102 as obsolete."},{"question":"Does 1722561102 include contacts?","answer":"No, contacts are not included with this housing.
