The MEMS resonator replaces the quartz crystal — no start-up time, no crystal load caps, and the frequency is set at the factory. The standby (power-down) function drops supply current to 1 µA, making this a fit for battery-powered equipment that sleeps between active periods. Microchip has marked the DSC1033BC2-012.0000 as Obsolete. Existing BOM lines can be filled through independent surplus channels — quantities are lot-specific and confirmed at RFQ. No official successor or pin-compatible replacement is listed by Microchip for this exact order code; a board-level review of the oscillator footprint and supply voltage is needed to identify a drop-in alternative from the current DSC1033 family. ## Commercial temperature grade and 4-SMD package The 4-SMD, no-lead package measures 5.00 mm x 3.20 mm with a seated height of 0.90 mm, a common footprint shared by many 4-pin oscillators. The CMOS output is compatible with most MCU clock inputs; the 3.3V supply is standard for digital logic.","metaTitle":"DSC1033BC2-012.0000 MEMS Oscillator 12 MHz CMOS XO Microchip","metaDescription":"DSC1033BC2-012.0000 Microchip MEMS XO, 12 MHz, CMOS, 3.3V, ±25ppm, 0°C to 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":"Tube","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":"±25ppm","Height - Seated (Max)":"0.035\\\" (0.90mm)","Operating Temperature":"0°C~70°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":"How can I order the DSC1033BC2-012.0000 or request a quote?","answer":"This part is obsolete and sourced through independent distribution.
