The DSC6101JI2A-006.1679T: Typical current draw is 3 mA, so the thermal impact on the 4-VLGA package is negligible even in a dense layout with limited airflow. For a 6.1679 MHz clock, that translates to ±154 Hz maximum deviation — well within the tolerance of a UART baud-rate generator or a CAN controller's PLL reference, but worth verifying if the clock feeds a precision timebase like an RTC or a high-speed ADC sampling clock.
The land pattern is a standard 4-pad VLGA — the two corner pads are the supply and ground, the centre pad is a thermal/mechanical anchor.
Sourcing reality — obsolete part, available through independent channels
No official successor or pin-compatible second source is recorded in the manufacturer's lifecycle documentation. Because the DSC61XX family uses a common MEMS die and package footprint, a functionally equivalent oscillator at the same frequency, supply voltage, and stability grade can be sourced from the same family (e.g., a non-AEC-Q100 variant) if the automotive qualification is not required. However, no direct drop-in replacement with identical order code exists — a BOM review is recommended before substituting.
