For RoHS-required builds, verify the exemption or consider a lead-free variant in the same series. The 1.27 mm pitch and 0.125 inch (3.18 mm) mating pin length are standard for AMPMODU System 50 receptacles. The 10-position dual-row layout mates with any System 50 socket that matches the same pitch, row spacing, and position count — confirm the receptacle part number against the BOM. Board locks are present on the SMD tails — they anchor the header during wave or selective solder reflow and provide mechanical retention against cable pull. ## Peer Comparison — 1-1871673-2 vs 104549-1 The 104549-1 offers 10 positions at 1.27 mm pitch with gold mating finish — a different density and plating grade for higher-cycle or denser board layouts.","metaTitle":"104549-1 TE Connectivity AMPMODU System 50 Header, SMD","metaDescription":"104549-1 TE Connectivity AMPMODU System 50 header, SMD, 10 positions, 1.27mm pitch, shrouded 4-wall, board lock, gold plating.","metaKeywords":null},"attributes":{"series":"AMPMODU System 50","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Board or Cable","Series":"AMPMODU System 50","Package":"Tube","Features":"Board Lock","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Surface Mount","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"2","Pitch - Mating":"0.050\\\" (1.27mm)","Product Status":"Active","Voltage Rating":"30VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.435\\\" (11.05mm)","Ingress Protection":"-","Base Product Number":"104549","Insulation Material":"Polyphthalamide (PPA)","Number of Positions":"10","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin-Lead","Contact Length - Post":"-","Current Rating (Amps)":"-","Operating Temperature":"-65°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.125\\\" (3.18mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"150.0µin (3.81µm)","Contact Finish Thickness - Mating":"30.0µin (0.76µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5300","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.53000","currency":"USD"},{"qty":10,"price":"$2.30100","currency":"USD"},{"qty":100,"price":"$2.02770","currency":"USD"},{"qty":500,"price":"$1.72350","currency":"USD"},{"qty":1000,"price":"$1.47005","currency":"USD"},{"qty":5000,"price":"$1.31798","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/3265947d51252aadfa2ec50ec549ec47.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy the 104549-1 connector?","answer":"The 104549-1 is sourced through independent distribution against an RFQ."},{"question":"Does 104549-1 have a board lock?","answer":"Yes, the header includes board locks on the SMD tails for reflow retention and mechanical resistance to cable strain."},{"question":"What is the pitch of the 104549-1 header?","answer":"The mating pitch is 1.27 mm (0.050 inch), with a row spacing of 2.54 mm (0.100 inch)."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/104549-1","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/104549-1 when reusing this data.
