The DSC61XX family is a standard commercial oscillator series, not screened to MIL-PRF or QML. ## Sourcing an obsolete MEMS XO Microchip has discontinued the DSC6121HI2A-00AR. No official successor order code is listed in the product record. For BOM lines that require this exact dual-frequency output and package, the remaining supply is held in independent distribution channels — surplus and new-old-stock lots confirmed at time of quote. Because the part is obsolete, a design-in for new production is not viable without a board spin to an active replacement. For existing assemblies, the dual 24 MHz / 48 MHz CMOS output is specific enough that a drop-in second source is unlikely; each RFQ lot should be inspected for date code consistency and traceability.","metaTitle":"Microchip DSC6121HI2A-00AR XO, 24MHz/48MHz CMOS, Obsolete","metaDescription":"Microchip DSC6121HI2A-00AR MEMS XO, 24MHz & 48MHz CMOS outputs, ±25ppm, 1.71-3.63V, -40°C~85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Height":"0.035\\\" (0.89mm)","Output":"CMOS","Series":"DSC61XX","Package":"Bag","Function":"-","Base Resonator":"MEMS","Package / Case":"4-VFLGA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.063\\\" L x 0.047\\\" W (1.60mm x 1.20mm)","Voltage - Supply":"1.71V ~ 3.63V","Frequency Stability":"±25ppm","Frequency - Output 1":"24MHz, 48MHz","Frequency - Output 2":"-","Frequency - Output 3":"-","Frequency - Output 4":"-","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (Typ)"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1700","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1228b1baf388c49094d52b76abcfca61.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Where can I buy DSC6121HI2A-00AR and how do I check stock?","answer":"Submit an RFQ for the quantity needed; the sourcing team will locate lots from surplus or new-old-stock channels and provide a firm price and lead time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC6121HI2A-00AR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC6121HI2A-00AR when reusing this data.
