The DSC6003JI2B-050.0000 is a 50 MHz XO from Microchip's DSC60XX family, built on a MEMS resonator rather than a quartz crystal — the MEMS die is sealed at wafer level, so the part resists shock and vibration better than a quartz can in the same footprint. Frequency stability is ±25 ppm across the full -40°C to +85°C industrial range, and the part is AEC-Q100 qualified, meaning it has passed the automotive-grade reliability stress suite (temperature cycling, ESD, latch-up).
Supply-rail flexibility and package footprint
The supply voltage range is 1.71 V to 3.63 V, which covers common logic rails — the same BOM line works across mixed-voltage designs without a separate regulator. Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.89 mm — the 0.098" × 0.079" footprint is a common 2.0 × 2.5 mm MEMS oscillator land pattern, so a layout designed for a SiTime or Abracon MEMS part accepts this drop-in.
