The dual-row arrangement (6 positions split across 2 rows) keeps the connector body compact in length — useful when the harness exits a panel cutout or a confined enclosure. The 0.181\" (4.60mm) row spacing is the same centre-to-centre distance between the two rows of the mating Power Double Lock header, so the header's solder tails land in a predictable grid. The Power Double Lock series uses a female socket terminal (typically TE part numbers 1-1703700-x or 1703700-x for the tin-plated version, or 1-1703701-x for gold) that crimps onto 18-22 AWG wire and inserts into the housing cavities. Without the contacts in hand, the housing is just a shell — the BOM must include both line items.","metaTitle":"TE 177901-4 Power Double Lock Plug Housing, 6 Pos","metaDescription":"TE Connectivity 177901-4 Power Double Lock plug housing, 6 positions, 2 rows, 3.96mm pitch, yellow PA66, latch lock, crimp termination, free hanging.","metaKeywords":null},"attributes":{"series":"Power Double Lock","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors","Connector Housings"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Note":"Contacts Not Included","Color":"Yellow","Pitch":"0.156\\\" (3.96mm)","Series":"Power Double Lock","Package":"Bulk","Features":"-","Row Spacing":"0.181\\\" (4.60mm)","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug","Fastening Type":"Latch Lock","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Base Product Number":"177901","Contact Termination":"Crimp","Insulation Material":"Polyamide (PA66), Nylon 6/6","Number of Positions":"6","Operating Temperature":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":[{"qty":1,"price":"$0.44000","currency":"USD"},{"qty":10,"price":"$0.40300","currency":"USD"},{"qty":25,"price":"$0.40120","currency":"USD"},{"qty":50,"price":"$0.39280","currency":"USD"},{"qty":100,"price":"$0.33570","currency":"USD"},{"qty":250,"price":"$0.30208","currency":"USD"},{"qty":500,"price":"$0.28532","currency":"USD"},{"qty":1000,"price":"$0.25007","currency":"USD"},{"qty":2500,"price":"$0.24839","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/177901-4/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 177901-4 available via RFQ confirmation?","answer":"The 177901-4 is sourced to order through independent distribution."},{"question":"What contacts fit 177901-4?","answer":"The 177901-4 accepts Power Double Lock female socket crimp terminals, typically TE part numbers 1-1703700-x (tin) or 1-1703701-x (gold), for 18-22 AWG wire.
