You must order the SL-156 crimp socket terminals separately (TE part numbers 1-1703459-1, 1703459-1, or similar depending on wire gauge and plating). The natural colour is the natural nylon colour — no dye added, which matters if you have a colour-coding requirement for the harness. It is a standard 0.156-inch centerline, which mates with TE SL-156 headers of the same pitch — the board footprint is defined by the header's through-hole pattern, not the housing. The -55°C to 105°C temperature range is the operating envelope for the nylon housing material — derate current through the contacts above 85°C per the terminal's derating curve, but the housing itself is stable across that span. The locking ramp and polarizing key together mean this is a vibration-resistant, error-proofed mate — suited for harnesses that get plugged and unplugged in the field, not a one-time solder joint. There is no secondary terminal position assurance (TPA) on this housing — the primary latch is the contact tang itself, so verify full insertion during assembly.","metaTitle":"TE SL-156 1-647402-2 Receptacle Housing, 12 Pos, 3.96mm","metaDescription":"TE Connectivity SL-156 receptacle housing, 12 positions, 0.156\" (3.96mm) pitch, natural nylon, locking ramp, polarizing key.","metaKeywords":null},"attributes":{"series":"SL-156","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":"Natural","Pitch":"0.156\\\" (3.96mm)","Series":"SL-156","Package":"Bulk","Features":"Polarizing Key","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Fastening Type":"Locking Ramp","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Base Product Number":"647402","Contact Termination":"Crimp","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"12","Operating Temperature":"-55°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7700","priceTiers":[{"qty":1,"price":"$1.77000","currency":"USD"},{"qty":10,"price":"$1.61500","currency":"USD"},{"qty":25,"price":"$1.56760","currency":"USD"},{"qty":50,"price":"$1.55160","currency":"USD"},{"qty":100,"price":"$1.44020","currency":"USD"},{"qty":250,"price":"$1.41632","currency":"USD"},{"qty":500,"price":"$1.28902","currency":"USD"},{"qty":1000,"price":"$1.15375","currency":"USD"},{"qty":2500,"price":"$1.06622","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-647402-2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 1-647402-2 and what is the price?","answer":"Current pricing and stock availability are confirmed at quote time — submit an RFQ for your target quantity and timeline."},{"question":"What contacts are compatible with 1-647402-2?","answer":"This housing requires SL-156 series crimp socket terminals, ordered separately — the housing does not include contacts.
