The DSC1001DI5-005.0196: Its AEC-Q100 qualification means it meets automotive reliability stress and temperature-grade requirements — suitable for under-hood or chassis-domain clock trees where a quartz crystal would need external load caps and a separate oscillator IC.
No pin-compatible second source is confirmed, but the DSC1001 series shares the same 4-SMD no-lead footprint across frequencies, so a frequency variant swap is a firmware change, not a board spin.
