The DSC1033BC2-012.0000 is a MEMS-based XO (Standard) oscillator from Microchip's PureSilicon™ series, delivering a 12 MHz CMOS output from a 3.3V supply rail. 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.
