Microchip lists the DSC1033DI1-020.0000T as Obsolete. For a new design, a current-production MEMS oscillator in the same 2.5 mm × 2.0 mm 4-SMD package should be evaluated — the DSC1033 series itself is discontinued, so the replacement will come from a different series or vendor. ## Industrial temperature grade and standby function Active draw is 3 mA typ at 20 MHz.","metaTitle":"DSC1033DI1-020.0000T MEMS Oscillator 20 MHz CMOS - Obsolete","metaDescription":"Microchip DSC1033DI1-020.0000T MEMS XO, 20 MHz, CMOS output, 3.3V, ±50ppm, -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)","Output":"CMOS","Series":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"20 MHz","Mounting Type":"Surface Mount","Base Resonator":"MEMS","Package / Case":"4-SMD, No Lead","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Size / Dimension":"0.098\\\" L x 0.079\\\" W (2.50mm x 2.00mm)","Voltage - Supply":"3.3V","Frequency Stability":"±50ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"-40°C~85°C","Current - Supply (Max)":"3mA (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/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1033DI1-020.0000T/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to the DSC1033DI1-020.0000T?","answer":"No official pin-compatible replacement has been announced by Microchip.
