AEC-Q100 grade — capable is not qualified
The DSC6101HL2B-072.5000 carries a named AEC-Q100 rating, meaning the part has passed the full suite of automotive-grade qualification tests — not just a datasheet temperature claim. Capable is not qualified; this is the qualification. That suits cabin and chassis modules; a grade-0 underhood location (125°C ambient) would require a different part.
72.5 MHz MEMS — why the resonator type matters for your BOM
A MEMS resonator replaces the quartz blank — the part survives 50,000 g shock and 70 g vibration without frequency shift, unlike a crystal that fractures under the same mechanical stress. For an engine control unit or transmission module on the same bracket as the drivetrain, that is the difference between a clock that stays locked and a field return.
Active — no last-time-buy clock ticking
The DSC61XXB family shares the same 4-VFLGA footprint and pinout across frequencies — a BOM change from 72.5 MHz to another frequency in the same family requires only a part-number swap, not a board spin.
