Tin is a cost-effective choice for moderate-cycle applications (50–100 mates) in clean, indoor environments. The 3 A ceiling keeps the temperature rise within the UL94 V-0 thermoplastic housing's limits across the -40°C to 80°C operating range. ## Mates with AMPMODU Mod II receptacles The 0.260\" (6.60 mm) mating pin length provides good wipe and contact engagement. For a wire-to-board application, pair it with a 24-position dual-row receptacle housing and matching crimp terminals — the detent lock on the header engages with the receptacle latch.","metaTitle":"280521-1 TE Connectivity AMPMODU Mod II Header 24 Pos 2.54mm","metaDescription":"280521-1 TE Connectivity AMPMODU Mod II header, 24 positions, 0.100\" (2.54 mm) pitch, dual-row, shrouded, detent lock, 3 A, tin contacts, 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":"Shrouded - 3 Wall","Termination":"Solder","Applications":"-","Contact Type":"Male Pin","Contact Shape":"Square","Mounting Type":"Through Hole","Connector Type":"Header","Fastening Type":"Detent Lock","Number of Rows":"2","Pitch - Mating":"0.100\\\" (2.54mm)","Product Status":"Active","Voltage Rating":"40V","lifecycle_stage":"unknown","Contact Material":"Brass","Insulation Color":"Black","Insulation Height":"0.496\\\" (12.60mm)","Ingress Protection":"-","Base Product Number":"280521","Insulation Material":"Thermoplastic","Number of Positions":"24","Row Spacing - Mating":"0.100\\\" (2.54mm)","Contact Finish - Post":"Tin","Contact Length - Post":"0.138\\\" (3.50mm)","Current Rating (Amps)":"3A","Operating Temperature":"-40°C ~ 80°C","Mated Stacking Heights":"-","Overall Contact Length":"0.563\\\" (14.30mm)","Contact Finish - Mating":"Tin","Contact Length - Mating":"0.260\\\" (6.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"118.1µin (3.00µm)","Contact Finish Thickness - Mating":"118.1µin (3.00µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2000","priceTiers":[{"qty":1,"price":"$2.20000","currency":"USD"},{"qty":10,"price":"$1.96000","currency":"USD"},{"qty":100,"price":"$1.77070","currency":"USD"},{"qty":500,"price":"$1.60162","currency":"USD"},{"qty":1000,"price":"$1.43251","currency":"USD"},{"qty":5000,"price":"$1.26340","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/280521-1/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 280521-1 and how do I get a price?","answer":"280521-1 is available to order through our distribution channel.
