It mates with AMPMODU Mod II receptacles and female socket housings that accept 0.025-inch square posts. Rated 3 A per contact with tin-on-tin mating surfaces (100.0 µinch tin over copper alloy). Tin plating is cost-effective for moderate mating cycles — expect 50–100 cycles before contact resistance drifts. ## Sourcing and compliance snapshot Sourced through independent distribution against your BOM quantity. Current pricing and lead time confirmed at RFQ — no stock-holding claim, no firm price on page. ## What mates with this header This unshrouded header mates with AMPMODU Mod II female socket housings (e.g., 5-146279 series) and crimp-socket terminals accepting 22–30 AWG wire. Confirm the mating housing's pin-entry depth to avoid bottoming out.","metaTitle":"5-146278-4 TE Connectivity AMPMODU Mod II Header, 4 Pos","metaDescription":"TE Connectivity AMP Connectors 5-146278-4 AMPMODU Mod II header, 4 positions, 0.100\" pitch, unshrouded, through-hole, tin plating, UL94 V-0.","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":"1","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":"146278","Insulation Material":"Liquid Crystal Polymer (LCP)","Number of Positions":"4","Row Spacing - Mating":"-","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":"Tin","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":"100.0µin (2.54µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4000","priceTiers":[{"qty":1,"price":"$0.40000","currency":"USD"},{"qty":10,"price":"$0.36200","currency":"USD"},{"qty":100,"price":"$0.30130","currency":"USD"},{"qty":500,"price":"$0.25612","currency":"USD"},{"qty":1000,"price":"$0.22449","currency":"USD"},{"qty":5000,"price":"$0.20038","currency":"USD"},{"qty":10000,"price":"$0.18646","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/9edac48721066d4749abbbad3dd5f4c8.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5-146278-4/alternatives.json"},"ai":{"faq":[{"question":"Is 5-146278-4 RoHS compliant?","answer":"Yes, it is RoHS compliant per the manufacturer's declaration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/5-146278-4","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/5-146278-4 when reusing this data.
