No official successor is documented. The part can be sourced through independent distribution on a lot-specific basis; confirm availability at RFQ."},{"question":"What is the replacement for DSC1018BC1-054.0000?","answer":"Microchip does not list a direct pin-compatible replacement for this order code. A functional equivalent would require matching 54 MHz, CMOS output, 1.8V supply, ±50 ppm stability, and the 4-SMD no-lead package — but no single Microchip order code is documented as a drop-in successor. A board-level change may be necessary."},{"question":"What supply voltage does the DSC1018BC1-054.0000 require?","answer":"The oscillator operates from a 1.8V supply rail. The input voltage must be within the device's specified range; a 3.3V or 2.5V rail would require a regulator or level translator."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1018BC1-054.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1018BC1-054.0000 when reusing this data.
