32.768 kHz MEMS XO — what the package and ratings mean for your board
The DSC6183CI2A-032K768: Rated AEC-Q100, the part is qualified for automotive-grade stress conditions (temperature cycling, ESD, latch-up), which matters if this oscillator feeds an RTC in an ECU or telematic control module.
Maximum supply current is 3 mA typical — at 32.768 kHz the dynamic current is dominated by the CMOS output drive into the load capacitance, not the MEMS element itself.
Obsolete — sourcing through independent distribution
The MEMS die and package are shared across the DSC61XX family — a functionally similar part at the same frequency may exist in a different stability or temperature grade, but a board spin or BOM change would be required for a drop-in replacement.
