1. SIT8208AI-G1-28E-62.500000X Substitution Conclusion This part can serve as a direct replacement for the original component. The only deviation is an increase in supply voltage from 2.5V to 2.8V. All other critical parameters—including frequency (62.5MHz), stability (±20ppm), output type, package footprint, and current characteristics—remain identical. When substituting based on voltage, it is essential to verify compatibility with the target system's power rail: if the system's power design has sufficient margin or supports adjustment, the replacement can proceed directly. If the system can only supply a strict 2.5V rail, it is necessary to validate whether the oscillator can reliably start up and maintain proper output levels at 2.5V. This requires consulting the specific datasheet for the minimum operating voltage specification; otherwise, reliability risks may arise.
