Its AEC-Q100 qualification means it's validated to automotive reliability standards — suitable for engine control units, ADAS sensors, and body electronics where a quartz crystal might fail under vibration or thermal shock. The 2.25V to 3.6V supply range covers 2.5V and 3.3V rails commonly found in automotive MCU clusters.
The 6-SMD package (7.00mm x 5.00mm, 0.90mm seated height) is a standard footprint shared across the DSC1121 series, making second-sourcing straightforward within the same family.
