That pitch packs 20 contacts per row into a footprint that fits a standard through-hole grid; the 0.145\" (3.68 mm) post length clears a typical 1.6 mm PCB with room for a solder fillet. ## Signal-level rating and temperature envelope Rated 30 VAC, which puts this squarely in signal-level duty — not for power distribution. ## Mechanical retention and polarization The shrouded 2-wall design with a latch holder gives this header a positive lock against vibration-induced disconnect — the latch engages the mating receptacle's ramp and holds until you squeeze the release. The 2-wall shroud also polarizes the mate, so you can't plug the receptacle in backwards.","metaTitle":"104666-3 TE AMPMODU System 50 Header 40 Pos 1.27mm","metaDescription":"104666-3 TE Connectivity AMPMODU System 50 header, 40 positions, 1.27mm pitch, through-hole, shrouded 2-wall, latch holder, gold mating, RoHS non-compliant.","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":"-","Shrouding":"Shrouded - 2 Wall","Termination":"Solder","Applications":"Automotive, General Purpose, Medical, Telecommunications","Contact Type":"Male Pin","Contact Shape":"Circular","Mounting Type":"Through Hole","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":"0.390\\\" (9.91mm)","Ingress Protection":"-","Base Product Number":"104666","Insulation Material":"Thermoplastic","Number of Positions":"40","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin-Lead","Contact Length - Post":"0.145\\\" (3.68mm)","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":"$12.6800","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$12.68000","currency":"USD"},{"qty":10,"price":"$11.46800","currency":"USD"},{"qty":100,"price":"$9.95090","currency":"USD"},{"qty":500,"price":"$9.52612","currency":"USD"},{"qty":1000,"price":"$8.49463","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/95614cf9e01a2e49b7509fc0ecd4a466.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/104666-3","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/104666-3 when reusing this data.
