No official cross-reference or second-source is published, so a board spin to a current Microchip MEMS oscillator (e.g., the DSC1000 or DSC8000 series) may be required for new designs. ## Temperature grade and supply rail — fit check Supply voltage is 1.8V only — the CMOS output swing is rail-to-rail, so the logic threshold scales with Vdd. A 3.3V oscillator will overdrive the input of a 1.8V-logic device unless a level translator is inserted; the standby (power-down) function pulls the supply current to 1 µA max when disabled.","metaTitle":"DSC1018BC1-054.0000T — Microchip MEMS Oscillator, 54 MHz","metaDescription":"Microchip DSC1018BC1-054.0000T XO (Standard) — 54 MHz CMOS output, MEMS resonator, 1.8V supply, ±50 ppm stability, 4-SMD.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Crystals & Oscillators"],"specifications":{"Mfr":"Microchip Technology","Type":"XO (Standard)","Output":"CMOS","Series":"DSC1018","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"54 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.197\\\" L x 0.126\\\" W (5.00mm x 3.20mm)","Voltage - Supply":"1.8V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°C","Current - Supply (Max)":"4mA (Typ)","Absolute Pull Range (APR)":"-","Spread Spectrum Bandwidth":"-","Current - Supply (Disable) (Max)":"1µA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0291cd7293e82768a7c2198660ff52d5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1018BC1-054.0000T/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for DSC1018BC1-054.0000T?","answer":"Microchip does not list a direct pin-compatible replacement for this part. For new designs, consider a current Microchip MEMS oscillator series such as the DSC1000 or DSC8000 — these offer similar package footprints and CMOS output but require a board-spin to verify pin compatibility and electrical ratings.
