The through-hole solder tails are 0.120\" (3.05mm) long, and the mating pin length is 0.230\" (5.84mm) — a common length for IDC ribbon-cable receptacles or individual crimp sockets. ## Gold mating finish vs tin post — the real durability difference The mating interface is gold over 15.0µin (0.38µm) thickness, while the solder tails are tin-plated at 100.0µin (2.54µm). The tin post is standard for soldering; the thickness is generous enough to wet well through wave or hand solder. The lifecycle status is Active. RoHS compliant. ## Peer check: 1376779-2 as a functional second-source The closest alternate in the same series is 1376779-2: same 40-position dual-row layout, same 0.100\" pitch, same 3 A rating, same UL94 V-0 LCP housing. The difference is the gold plating thickness on the mating surface — 8.00µin (0.203µm) vs the 15.0µin on 7-146256-0. For low-cycle or cost-sensitive builds, 1376779-2 is a drop-in; for high-reliability or frequent re-mating, the thicker gold on 7-146256-0 is the better call.","metaTitle":"7-146256-0 TE AMPMODU Mod II Header 40 Pos 2.54mm","metaDescription":"7-146256-0 TE Connectivity AMP Connectors AMPMODU Mod II unshrouded breakaway header, 40 positions, 0.100\" pitch, gold mating finish, 3 A.","metaKeywords":null},"attributes":{"series":"AMPMODU Mod II","packageCase":null,"mountingType":null,"rohsStatus":"RoHS Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Pin Headers"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Style":"Board to Board or Cable","Series":"AMPMODU Mod II","Package":"Bulk","Features":"-","Shrouding":"Unshrouded","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header, Breakaway","Fastening Type":"Push-Pull","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"-","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Black","Insulation Height":"0.090\\\" (2.29mm)","Ingress Protection":"-","Base Product Number":"146256","Insulation Material":"Liquid Crystal Polymer (LCP)","Number of Positions":"40","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.120\\\" (3.05mm)","Current Rating (Amps)":"3A","Operating Temperature":"-65°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.440\\\" (11.18mm)","Contact Finish - Mating":"Gold","Contact Length - Mating":"0.230\\\" (5.84mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"100.0µin (2.54µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9900","priceTiers":[{"qty":1,"price":"$7.99000","currency":"USD"},{"qty":10,"price":"$6.96200","currency":"USD"},{"qty":100,"price":"$6.19260","currency":"USD"},{"qty":500,"price":"$5.78950","currency":"USD"},{"qty":1000,"price":"$5.16658","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/7-146256-0/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/7-146256-0","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/7-146256-0 when reusing this data.
