1. SIT8208AI-G2-28E-62.500000T Substitution Conclusion
The difference between this part and the original model lies in the operating voltage (2.8V vs. 3.3V). Other key parameters such as frequency, stability, package, output type, and current consumption remain identical. Direct substitution is not feasible because the voltage mismatch would prevent the original 3.3V power supply system from providing the correct voltage to the 2.8V device, potentially causing abnormal output levels or device damage. If the system supply can be adjusted to 2.8V, functional compatibility may be achieved, but a reassessment of the power design and signal level compatibility is required.
2. SIT8208AI-G2-28E-62.500000X Substitution Conclusion
This model shares identical electrical parameters with the T-suffix version described above. The only difference is the suffix code (X vs. T), which typically indicates non-electrical variations such as packaging or order code, with no change in technical specifications. Therefore, the substitution conclusion aligns with that of the T version: the voltage discrepancy prevents direct replacement of the original 3.3V model, but functional replacement is possible if the system voltage is adapted to 2.8V. The X and T versions can be considered electrically equivalent.
