Operating from a 2.5V to 3.3V supply rail, the oscillator draws 27mA typical during operation and 23mA when the output is disabled via the enable/disable pin — useful for power-gating the clock tree in battery-backed or mixed-voltage domains.
Housed in a 6-VDFN package measuring 7.00mm x 5.00mm with a seated height of 0.90mm, the DSC1221NI1-33M00000 is a surface-mount oscillator that shares the same 6-pin footprint as other DSC12X1 variants, simplifying layout reuse across frequency options.

Yes, it carries AEC-Q100 rating, qualifying it for automotive applications including under-hood and cabin electronics where reliability stress testing and PPAP are required.
This is the total allowable deviation including temperature, supply voltage, and aging effects.
A quartz oscillator with the same 33 MHz frequency, CMOS output, ±50ppm stability, and 6-VDFN footprint could be a functional equivalent, but the MEMS base resonator offers different vibration and aging characteristics. Confirm the specific quartz part's phase-noise profile and startup time against your application's requirements before substitution.
