For continuous operation near the 105°C upper limit, derate the current per the manufacturer's curve — the 3A rating is at 25°C ambient. This header mates with Molex SL series crimp housings (e.g., 70066 series) that accept 22-26 AWG wire with the matching crimp terminals. The 0.240\" (6.10mm) mating pin length provides good contact wipe on insertion. The through-hole leads are 0.025\" square, compatible with most wave-solder processes.","metaTitle":"Molex 171974-0104 SL Header, 4-Pin, 2.54mm, Right-Angle","metaDescription":"Molex 171974-0104 SL series 4-position shrouded header, 0.100\" pitch, through-hole right-angle, 15µin gold mating finish, 3A, 250V.","metaKeywords":null},"attributes":{"series":"SL 171974","packageCase":null,"mountingType":null,"rohsStatus":"RoHS non-compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"Molex","Style":"Board to Cable/Wire","Series":"SL 171974","Package":"Tube","Features":"Polarizing Key","Shrouding":"Shrouded - 4 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole, Right Angle","Connector Type":"Header","Fastening Type":"Latch Holder","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.276\\\" (7.00mm)","Ingress Protection":"-","Base Product Number":"171974","Insulation Material":"Liquid Crystal Polymer (LCP)","Number of Positions":"4","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.130\\\" (3.30mm)","Current Rating (Amps)":"3A","Operating Temperature":"-40°C~105°C","Mated Stacking Heights":"-","Overall Contact Length":"-","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.240\\\" (6.10mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"78.7µin (2.00µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9800","stockQuantity":0,"priceTiers":[{"qty":39,"price":"$0.98000","currency":"USD"},{"qty":42,"price":"$0.88000","currency":"USD"},{"qty":420,"price":"$0.85000","currency":"USD"},{"qty":840,"price":"$0.82000","currency":"USD"},{"qty":1680,"price":"$0.81000","currency":"USD"},{"qty":2520,"price":"$0.70000","currency":"USD"},{"qty":5040,"price":"$0.61000","currency":"USD"},{"qty":10038,"price":"$0.55000","currency":"USD"},{"qty":25032,"price":"$0.54000","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"isd-matrix-langgraph","citationUrl":"https://icsourcedirect.com/molex/171974-0104","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/molex/171974-0104 when reusing this data.
