The DSC1001DI2-028.6363B: AEC-Q100 Grade qualification means this part has passed the automotive reliability stress tests — temperature cycling, ESD, latch-up — making it suitable for under-hood and chassis-domain applications where a quartz oscillator's shock and vibration sensitivity can be a failure point.
Operating from a 1.8V to 3.3V supply rail, this oscillator fits designs that migrate between voltage domains without a separate level translator for the clock signal.
This part is in production and can be designed into new builds without a last-time-buy window.
