1. SIT8208AI-G1-28E-62.500000X Substitution Conclusion
This model can serve as a direct replacement for the original part, with the primary consideration being the supply voltage difference: it operates at 2.8V versus the original's 2.5V. If the target circuit is powered at 2.5V, direct substitution may cause oscillator malfunction or increased power consumption. System power compatibility must therefore be verified. All other critical parameters—including frequency, stability, package, enable function, and output type—are identical. Substitution is viable provided the voltage requirement is met.
2. SIT8208AI-G1-28E-62.500000Y Substitution Conclusion
Substitution with this model requires careful evaluation. The operating voltage differs (2.8V vs. 2.5V), similar to the X variant. Additionally, the suffix “Y” versus the original “X” may indicate unspecified internal configuration or test standard differences—such as frequency deviation characteristics or production lot specifications—which could lead to performance variance under extreme temperature conditions. It is recommended to consult the SiTime product documentation to clarify the specific definitions of the “X” and “Y” suffixes. If the only difference is voltage and the system supports 2.8V, substitution may be acceptable; otherwise, compatibility should be validated in the actual application environment.
