Gold plating on the mating pins (15.0µin) supports repeated connect/disconnect cycles without contact fretting, while the tin-plated solder tails keep the board-side cost in check. In a 24-position fully loaded connector, the total current per row is 36A, but the board trace and receptacle rating will set the real limit. The square pin profile (0.025\" square typical for AMPMODU) accepts standard crimp-socket or IDC receptacles from the same series.","metaTitle":"280521-2 TE Connectivity AMPMODU Mod II Header, 24-Pos","metaDescription":"280521-2 is an active 24-position, dual-row, shrouded header from TE's AMPMODU Mod II series. 0.100\" pitch, gold mating finish, rated 3A/40V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings"],"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":"Gold","Contact Length - Mating":"0.260\\\" (6.60mm)","Number of Positions Loaded":"All","Material Flammability Rating":"UL94 V-0","Contact Finish Thickness - Post":"98.4µin (2.50µm)","Contact Finish Thickness - Mating":"15.0µin (0.38µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.6500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/d28062dc06fedff20653dabaaaa1c205.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/280521-2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy 280521-2?","answer":"280521-2 is sourced to order through our distribution channel."},{"question":"Is 280521-2 compatible with AMPMODU Mod II receptacles?","answer":"Yes — it is designed to mate with AMPMODU Mod II receptacles from the same series.
