The DSC6101JL2B-033.3333: The MEMS resonator inside means no quartz crystal to crack under reflow stress; the part handles the standard lead-free profile without a bake step as long as the MSL is observed.
Temperature grade and automotive qualification
Frequency stability is ±25ppm across the temperature range, so a 33.3333 MHz clock stays within 833 Hz of nominal at the extremes — tight enough for CAN FD, Ethernet, or USB interfaces that require a precise reference.
No pin-compatible second-source alternative is listed on the official record.
