The DSC1033CE1-003.5000 is a MEMS-based XO (Standard) from Microchip's PureSilicon™ series, delivering a fixed 3.5 MHz CMOS output from a 3.3V rail. The 4-SMD no-lead package (3.20 mm × 2.50 mm footprint, 0.90 mm seated height) is a common MEMS oscillator land pattern; board layout matches industry-standard 2.5×3.2 mm pads.
Active current is 3 mA typical (max), making it a low-power clock source for always-on microcontroller or sensor hub applications.
Microchip has not published a direct pin-compatible replacement for this exact frequency and package. For a new design, consider a current-production MEMS oscillator in the same 2.5×3.2 mm footprint, 3.3V, CMOS output — the frequency and stability requirements will determine the closest match.
Yes — the part includes a standby (power-down) feature that reduces supply current to 1 µA max while keeping the MEMS resonator biased for fast wake-up.
