Alternative Part
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 2.8V Enable/Disable 4-SMD, No Lead

1. SIT8208AI-G1-28E-62.500000X Substitution Conclusion
This part cannot serve as a direct substitute for the original component. The discrepancy lies in its operating voltage of 2.8V, compared to the original's 3.3V. Installing this 2.8V device directly onto a power rail designed for the original 3.3V component would result in a voltage mismatch. This could lead to abnormal output levels, timing errors, or even damage to the device itself or downstream load circuits. It constitutes a fundamental power compatibility issue, therefore direct substitution is not viable.
2. SIT8208AI-G1-28E-62.500000Y Substitution Conclusion
This model is likewise unsuitable as a direct replacement for the original part. Its core technical specifications are identical to the previous model (X), with the same key difference: an operating voltage of 2.8V, which is incompatible with the original 3.3V requirement. While the suffix change from "X" to "Y" may indicate an internal production lot, test specification, or minor feature revision, the critical electrical parameters are listed as identical. Consequently, the fundamental limitation of voltage mismatch remains. Direct replacement carries the same power compatibility and reliability risks outlined for the previous model and is therefore not feasible.
