The DSC1001DI1-009.8304T: AEC-Q100 qualification certifies the part for automotive-grade reliability — the temperature range and stress screening match the requirements of under-hood and cabin electronics, not just commercial equipment. Supply voltage spans 1.8V to 3.3V, so the same order code can serve a 1.8V MCU core clock and a 3.3V peripheral bus without a separate voltage rail for the oscillator.
For a battery-backed ECU or a sensor node that sleeps most of the time, that 15 µA standby current is the dominant draw when the clock is disabled; it keeps the quiescent load well below the self-discharge rate of a coin cell.
Package, footprint, and board assembly
Housed in a 4-SMD no-lead package measuring 2.50 mm × 2.00 mm with a seated height of 0.90 mm — the compact footprint suits space-constrained automotive modules and portable electronics.
