This is common for low-cost, low-density interconnects where the mating connector is a standard female socket housing. ## Current and contact finish Rated 3A per contact. Tin-plated mating surface (, 100µin thickness) is fine for occasional mating — expect around 50-100 cycles before the tin begins to fret in a high-vibration environment. LCP handles reflow temperatures well and resists moisture absorption, which matters for conformal-coated boards. Termination is solder, through-hole. The post finish is tin (, 100µin) — solderable with standard rosin flux. No press-fit or IDC option on this part.","metaTitle":"5-146278-3 TE Connectivity AMPMODU Mod II Header, 3 Pos","metaDescription":"5-146278-3 TE Connectivity AMP Connectors AMPMODU Mod II unshrouded header, 3 positions, 0.100\" (2.54mm) pitch, tin plating, 3A, UL94 V-0.","metaKeywords":null},"attributes":{"series":"AMPMODU Mod II","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 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":"3","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":"$0.3300","priceTiers":[{"qty":1,"price":"$0.33000","currency":"USD"},{"qty":10,"price":"$0.28500","currency":"USD"},{"qty":100,"price":"$0.25860","currency":"USD"},{"qty":500,"price":"$0.20076","currency":"USD"},{"qty":1000,"price":"$0.18660","currency":"USD"},{"qty":5000,"price":"$0.16534","currency":"USD"},{"qty":10000,"price":"$0.14644","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/5-146278-3/alternatives.json"},"ai":{"faq":[{"question":"What is the compatible mating connector for 5-146278-3?","answer":"Common mates include AMPMODU Mod II receptacles or generic 0.100\" pitch crimp housings.
