The AEC-Q100 rating confirms it passed automotive-grade reliability stress, so it belongs on an ECU board that sees under-hood ambient temps.
Maximum supply current when enabled is 35 mA; pulling the Enable/Disable pin low drops it to 22 mA max. That 13 mA saving matters in a battery-backed module that sleeps between CAN wake events.
Housed in a 6-SMD, No Lead package measuring 3.20 mm x 2.50 mm with a seated height of 0.90 mm. The 0.126" x 0.098" footprint matches industry-standard 3.2 x 2.5 mm oscillator pads — no layout surprises if you are swapping from a quartz XO of the same size. Surface-mount only; no through-hole variant.
The base product number is DSC1121, and the DSC1121 series remains in current manufacture.
