The 4-SMD, no-lead package measures 5.00mm x 3.20mm with a seated height of 0.90mm — a standard footprint that swaps onto most 12 MHz oscillator pads without a board spin. ## Standby function and power draw A Standby (Power Down) pin lets the system shut the oscillator off: max supply current is 3 mA typical when running, dropping to 1 µA in disable — useful for battery-powered designs that need to wake on an external event. Microchip lists the DSC1033BI1-012.0000T as Obsolete. Available through independent surplus channels in lot-specific quantities. A quote against your BOM line confirms current availability and pricing — no stock-holding claim is made here.","metaTitle":"DSC1033BI1-012.0000T MEMS Oscillator 12 MHz CMOS - Microchip","metaDescription":"DSC1033BI1-012.0000T Microchip MEMS XO, 12 MHz, CMOS output, 3.3V, -40°C~85°C, 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":"DSC1033, PureSilicon™","Package":"Tape & Reel (TR)","Ratings":"-","Function":"Standby (Power Down)","Frequency":"12 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":"-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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/39044fcc9825a23a0d54b2590f18614f.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is DSC1033BI1-012.0000T compatible with 3.3V logic?","answer":"Yes.
