The 0.232\" (5.90mm) row spacing and 2-row layout accept a standard Multi-Lock terminal, and the free-hanging (in-line) mounting means this plug is the cable-side half, not a panel or PCB mount. ## Sourcing — Active, But Confirm the Terminal A BOM line for 1-173851-1 alone is incomplete — the terminal part number must be added before the harness can be assembled. The 1-173851-1 is a plug housing — it mates with the matching Multi-Lock receptacle (header or housing) of the same 12-position, 2-row, 3.50mm pitch layout. The latch holder provides audible and tactile lock confirmation during assembly. The 2-row arrangement with 0.232\" (5.90mm) row spacing gives the terminals mechanical stability and keeps the mated connector from rocking under cable strain.","metaTitle":"TE 1-173851-1 Multi-Lock Plug Housing, 12 Pos, 3.50mm","metaDescription":"TE 1-173851-1 Multi-Lock plug housing, 12 circuits, 2-row, 3.50mm pitch, crimp termination, free-hanging, -30°C to 105°C.","metaKeywords":null},"attributes":{"series":"Multi-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":"White","Pitch":"0.138\\\" (3.50mm)","Series":"Multi-Lock","Package":"Tray","Features":"-","Row Spacing":"0.232\\\" (5.90mm)","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Plug","Fastening Type":"Latch Holder","Number of Rows":"2","Product Status":"Active","lifecycle_stage":"unknown","Base Product Number":"173851","Contact Termination":"Crimp","Insulation Material":"Polybutylene Terephthalate (PBT)","Number of Positions":"12","Operating Temperature":"-30°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4500","priceTiers":[{"qty":1,"price":"$1.45000","currency":"USD"},{"qty":10,"price":"$1.35100","currency":"USD"},{"qty":25,"price":"$1.30120","currency":"USD"},{"qty":100,"price":"$1.16290","currency":"USD"},{"qty":300,"price":"$1.12520","currency":"USD"},{"qty":500,"price":"$1.02462","currency":"USD"},{"qty":1000,"price":"$0.91776","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-173851-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy the TE 1-173851-1?","answer":"Submit an RFQ for your BOM quantity."},{"question":"What contacts are used with 1-173851-1?","answer":"The 1-173851-1 is a plug housing only — contacts are not included. It accepts TE Multi-Lock female socket crimp terminals (typically from the 173851 series), which must be ordered separately.
