No secondary latch or TPA is present; the lock relies on the interference fit between the header and receptacle. ## Through-hole solder termination, tin contacts Termination is through-hole solder, with the contact post measuring 0.140\" (3.56mm) long — sufficient for a standard 1.6mm PCB. Both the mating and post finishes are tin. Tin contacts are rated for fewer mating cycles than gold — typically 25–50 cycles — but carry adequate current for signal and low-power applications.","metaTitle":"2-640456-4 TE Connectivity MTA-100 Header 24 Pos 2.54mm","metaDescription":"2-640456-4 TE Connectivity AMP Connectors MTA-100 header, 24 circuits, 0.100\" (2.54mm) pitch, single row, friction lock, through-hole solder, tin contacts","metaKeywords":null},"attributes":{"series":"MTA-100","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 Cable/Wire","Series":"MTA-100","Package":"Bulk","Features":"-","Shrouding":"Shrouded - 1 Wall","Termination":"Solder","Applications":"General Purpose","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Friction Lock","Number of Rows":"1","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"250VAC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Insulation Color":"Natural","Insulation Height":"0.305\\\" (7.75mm)","Ingress Protection":"-","Base Product Number":"640456","Insulation Material":"Thermoplastic","Number of Positions":"24","Row Spacing - Mating":"-","Contact Finish - Post":"Tin","Contact Length - Post":"0.140\\\" (3.56mm)","Current Rating (Amps)":"Varies by Wire Gauge","Operating Temperature":"-55°C ~ 105°C","Mated Stacking Heights":"-","Overall Contact Length":"0.535\\\" (13.59mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.295\\\" (7.49mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"-","Contact Finish Thickness - Mating":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.9200","priceTiers":[{"qty":1,"price":"$1.92000","currency":"USD"},{"qty":10,"price":"$1.75800","currency":"USD"},{"qty":100,"price":"$1.56720","currency":"USD"},{"qty":500,"price":"$1.40270","currency":"USD"},{"qty":1000,"price":"$1.25550","currency":"USD"},{"qty":5000,"price":"$1.12562","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/4cc8df2439f1356c1edad4a3b317c669.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/2-640456-4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the 2-640456-4 in the MTA-100 series?","answer":"For a 24-position header with a friction lock, the 2-640456-4 is the standard offering; no identical pin-compatible alternate is listed.
