For a 9-circuit harness, you need 9 individual crimp contacts plus the housing. The SL-156 series uses standard TE crimp terminals; confirm the wire gauge range (typically 18-24 AWG for this series) matches your harness build before committing the BOM. ## Mating Header and Panel Fit The 640251-9 mates with the matching SL-156 series PCB headers at the same 0.156\" (3.96mm) pitch. The 9-position count matches a 9-pin header; verify the header's keying and latch orientation align with your harness routing before ordering production quantities.","metaTitle":"TE Connectivity SL-156 640251-9","metaDescription":"TE Connectivity SL-156 640251-9 receptacle housing, 9 positions, 0.156\" (3.96mm) pitch, natural nylon, crimp termination, contacts not included.","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":"-","Row Spacing":"-","Contact Type":"Female Socket","Mounting Type":"Free Hanging (In-Line)","Connector Type":"Receptacle","Fastening Type":"-","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Base Product Number":"640251","Contact Termination":"Crimp","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"9","Operating Temperature":"-55°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6000","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$0.60000","currency":"USD"},{"qty":10,"price":"$0.56200","currency":"USD"},{"qty":25,"price":"$0.55960","currency":"USD"},{"qty":50,"price":"$0.54540","currency":"USD"},{"qty":100,"price":"$0.46780","currency":"USD"},{"qty":250,"price":"$0.42312","currency":"USD"},{"qty":500,"price":"$0.39962","currency":"USD"},{"qty":1000,"price":"$0.35025","currency":"USD"},{"qty":2500,"price":"$0.34555","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/5955c3cb0fb4a562bfe0ff9747625590.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy 640251-9 and get a price?","answer":"The 640251-9 is sourced to order through independent distribution — submit an RFQ for current pricing and availability."},{"question":"Does 640251-9 include contacts?","answer":"No — the listing explicitly notes that contacts are not included.
