Its AEC-Q100 rating means it passed the automotive reliability stress suite — temperature cycling, ESD, and latch-up — making it suitable for engine-bay or cabin ECUs where a quartz crystal might drift under vibration. ## Temperature range and standby power The standby (power-down) function drops supply current to 15 µA max — useful for battery-backed modules that need to wake on a bus event without draining the cell during sleep. Housed in a 4-SMD, no-lead package measuring 3.20mm x 2.50mm with a seated height of 0.90mm. The 0.126\" x 0.098\" footprint is common across the DSC1001 family, so a single PCB layout can serve multiple frequency variants without a board spin. No pin-compatible second source is listed, but the DSC1001 series shares the same package and pinout across frequencies, so a different frequency variant can be swapped in if the BOM frequency changes.","metaTitle":"DSC1001CL2-026.6600T MEMS Oscillator – 26.66 MHz, AEC-Q100","metaDescription":"Microchip DSC1001CL2-026.6600T: 26.66 MHz XO, CMOS, AEC-Q100, -40°C to 105°C, 1.8V-3.3V supply, 15 µA standby.
