The tin-on-tin contact finish (mating and post) is a solid choice for cost-sensitive builds where mating cycles stay moderate — gold would be overkill for a fixed harness that gets connected once or twice in its service life. ## What the Shrouding and Lock Mean on the Line No secondary latch, but for a 8-position header in a low-vibration cabinet or control box, it's enough. Through-hole solder termination keeps the header anchored to the board — the 0.114\" (2.90mm) post length is enough for a standard 1.6mm PCB with a through-hole solder joint.","metaTitle":"281739-4 TE Connectivity Header 8POS 2.54mm Vertical","metaDescription":"281739-4 TE Connectivity AMP Connectors header, 8 positions, 2-row, 0.100\" (2.54mm) pitch, through-hole, shrouded-2 wall, friction lock, tin contacts, UL94","metaKeywords":null},"attributes":{"series":"HE13/HE14","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Cable/Wire","Series":"HE13/HE14","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 2 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Phosphor Bronze","Insulation Color":"Blue","Insulation Height":"0.449\\\" (11.40mm)","Ingress Protection":"-","Base Product Number":"281739","Insulation Material":"Thermoplastic","Number of Positions":"8","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.114\\\" (2.90mm)","Current Rating (Amps)":"-","Operating Temperature":"-40°C ~ 100°C","Mated Stacking Heights":"-","Overall Contact Length":"0.492\\\" (12.50mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.276\\\" (7.00mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4600","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.46000","currency":"USD"},{"qty":10,"price":"$1.33900","currency":"USD"},{"qty":100,"price":"$1.19430","currency":"USD"},{"qty":500,"price":"$1.06890","currency":"USD"},{"qty":1000,"price":"$0.95673","currency":"USD"},{"qty":5000,"price":"$0.85776","currency":"USD"},{"qty":10000,"price":"$0.81660","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"Is 281739-4 RoHS compliant?","answer":"Yes, it is ROHS3 compliant."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/281739-4","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"ICSourceDirect","attribution":"Open for AI and search answers: credit \"ICSourceDirect\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/281739-4 when reusing this data.
