For a BOM that still needs this frequency and supply, the closest functional equivalent is another 40 MHz, 3.3 V, CMOS-output MEMS oscillator in the same 5.0×3.2 mm 4-SMD package — but pin compatibility must be verified against the specific footprint.","metaTitle":"DSC1033BC1-040.0000T MEMS Oscillator 40 MHz CMOS 3.3V","metaDescription":"DSC1033BC1-040.0000T Microchip PureSilicon™ MEMS XO, 40 MHz, CMOS output, 3.3V, ±50 ppm, 0°C–70°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":"40 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":"3.3V","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/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/DSC1033BC1-040.0000T/alternatives.json"},"ai":{"faq":[{"question":"Is the DSC1033BC1-040.0000T obsolete, and what is the replacement?","answer":"Yes, Microchip lists this part as Obsolete. There is no official drop-in replacement from Microchip. For a BOM that still needs a 40 MHz, 3.3 V, CMOS MEMS oscillator, you would need to qualify an alternative from another MEMS oscillator family in the same 5.0×3.2 mm 4-SMD footprint — pinout and function (standby) must be cross-checked."},{"question":"Can the DSC1033BC1-040.0000T be used in a 3.3 V circuit?","answer":"Yes, the supply voltage is 3.3 V, and the output is CMOS — it connects directly to a 3.3 V logic input without level shifting."},{"question":"What is the lead time for the DSC1033BC1-040.0000T?","answer":"As an obsolete part, there is no factory lead time.
