The natural nylon body carries a polarizing key and a locking ramp, so it locks onto the mating header and won't shake loose in a harness that sees vibration. Typical use is wire-to-board power and signal interconnects inside industrial control cabinets, appliances, and automotive interior harnesses where the 3.96mm pitch gives enough room for moderate current per circuit without crowding the board. The 0.156\" (3.96mm) pitch sets the board footprint — it's wider than the common 2.54mm pitch, so the header footprint takes more board space but gives better creepage for higher-voltage or moderate-current runs. The locking ramp is the real field feature: once the housing mates with the SL-156 header, the ramp snaps over the header latch and holds the pair together against cable yank and machine vibration. The polarizing key on the housing aligns with a slot on the header — you can't plug it in backwards, which saves a rework step on the line. The crimp termination means you use a standard hand or pneumatic crimp tool for the matching SL-156 socket terminal; no soldering, no IDC tooling. ## Sourcing and Lifecycle If you're filling a BOM line for a 14-position SL-156 receptacle, this is the direct housing match.","metaTitle":"TE 1-770849-4 SL-156 Receptacle Housing, 14 Pos, 3.96mm","metaDescription":"TE 1-770849-4 SL-156 14-position receptacle housing, 0.156\" (3.96mm) pitch, natural nylon, polarizing key, locking ramp.","metaKeywords":null},"attributes":{"series":"SL-156","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"770849","Contact Termination":"Crimp","Insulation Material":"Polyamide (PA), Nylon","Number of Positions":"14","Operating Temperature":"-55°C ~ 105°C"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7200","priceTiers":[{"qty":1,"price":"$0.72000","currency":"USD"},{"qty":10,"price":"$0.69800","currency":"USD"},{"qty":25,"price":"$0.69480","currency":"USD"},{"qty":50,"price":"$0.67120","currency":"USD"},{"qty":100,"price":"$0.56270","currency":"USD"},{"qty":250,"price":"$0.52756","currency":"USD"},{"qty":500,"price":"$0.49824","currency":"USD"},{"qty":1000,"price":"$0.43669","currency":"USD"},{"qty":2500,"price":"$0.41324","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-770849-4/alternatives.json"},"ai":{"faq":[{"question":"Is 1-770849-4 polarized?","answer":"Yes, the housing includes a polarizing key that prevents incorrect mating orientation with the SL-156 header.
