Contacts are copper alloy with 20.0µin (0.51µm) gold finish, suited for repeated mating cycles in test or interconnect applications where wiping action maintains low resistance. ## Pitch and footprint fit At 0.100\" (2.54mm) pitch, the 821-22-004-10-000101 shares the same board footprint as standard 0.100\" headers — the single-row layout occupies minimal board edge and routes easily on two-layer boards.","metaTitle":"Mill-Max 821-22-004-10-000101 Spring-Loaded Piston","metaDescription":"Mill-Max 821-22-004-10-000101 spring-loaded piston connector: 4 contacts, single row, 0.100\" (2.54mm) pitch, gold plating 20.0µin, through-hole, bulk.","metaKeywords":null},"attributes":{"series":"821","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Pin Headers, Sockets & Housings","Spring-Loaded Contacts"],"specifications":{"Mfr":"Mill-Max Manufacturing Corp.","Pitch":"0.100\\\" (2.54mm)","Series":"821","Package":"Bulk","Material":"Copper Alloy","Row Spacing":"-","Mounting Type":"Through Hole","Connector Type":"Piston","Contact Finish":"Gold","Number of Rows":"1","Product Status":"Active","lifecycle_stage":"unknown","Number of Contacts":"4","Base Product Number":"821-22","Contact Finish Thickness":"20.0µin (0.51µm)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.5300","priceTiers":[{"qty":1,"price":"$2.53000","currency":"USD"},{"qty":10,"price":"$2.29300","currency":"USD"},{"qty":25,"price":"$2.17200","currency":"USD"},{"qty":50,"price":"$2.12160","currency":"USD"},{"qty":100,"price":"$2.02060","currency":"USD"},{"qty":250,"price":"$1.76808","currency":"USD"},{"qty":500,"price":"$1.71754","currency":"USD"},{"qty":1000,"price":"$1.46497","currency":"USD"},{"qty":2500,"price":"$1.36394","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/821-22-004-10-000101/alternatives.json"},"ai":{"faq":[{"question":"What is the pitch and contact count for this spring-loaded piston?","answer":"The 821-22-004-10-000101 has 4 contacts in a single row at 0.100\" (2.54mm) pitch."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/mill-max-manufacturing-corp/821-22-004-10-000101","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/mill-max-manufacturing-corp/821-22-004-10-000101 when reusing this data.
