The 4-SMD, No Lead package (5.00mm x 3.20mm) is a standard footprint that matches many quartz oscillator pads — a direct swap in most cases if the supply voltage matches. ## Automotive-grade timing: AEC-Q100 and temperature range If you are replacing a quartz part in an ECU or sensor module, the AEC-Q100 stamp is your assurance it will survive the same thermal cycles. The MEMS resonator does not have the aging drift of quartz, so the ppm stays closer to the initial spec over the product life. That is useful for battery-backed modules or systems that sleep between events — the oscillator itself is not burning 6.3 mA while the rest of the board is in deep sleep.","metaTitle":"DSC1001BI2-025.5500T Microchip MEMS XO, 25.55 MHz, AEC-Q100","metaDescription":"DSC1001BI2-025.5500T: Microchip MEMS XO, 25.55 MHz CMOS, -40°C to 85°C, AEC-Q100, standby function.

The MEMS resonator is more shock-tolerant than quartz, and the AEC-Q100 qualification means it meets automotive reliability standards.
