We source it through independent distribution channels — quantities are lot-specific and confirmed at RFQ. Submit a request with your target quantity and we'll quote against available inventory."},{"question":"What is the replacement for DSC1033DI1-033.3300T?","answer":"No direct pin-compatible successor is listed by Microchip for the DSC1033DI1-033.3300T. Any replacement will require evaluating the clock tree for frequency, voltage, stability, and package compatibility. A same-function MEMS oscillator from the DSC11xx or DSC60xx series may fit, but pinout and electrical characteristics must be verified against the original datasheet."},{"question":"What is the frequency tolerance of DSC1033DI1-033.3300T?","answer":"±50 ppm frequency stability over the operating temperature range."},{"question":"Can I use a 3.3V oscillator as replacement for DSC1033DI1-033.3300T?","answer":"Yes, the DSC1033DI1-033.3300T runs on 3.3V supply. Any replacement must also be 3.3V, match the 33.33 MHz frequency, and have the same package footprint. CMOS output and ±50 ppm or better stability are required to maintain timing margin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1033DI1-033.3300T","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1033DI1-033.3300T when reusing this data.
