1. SIT8208AI-G2-28E-62.500000T Substitution Conclusion
The primary difference between this model and the original (3.3V) version is its 2.8V supply voltage, while other key parameters—frequency, stability, package, current consumption, etc.—remain identical. Direct substitution is not feasible. If the target circuit operates at 3.3V, the 2.8V device may be damaged due to overvoltage, or its output levels may mismatch, leading to timing errors or degraded signal integrity. If the circuit supply can be adjusted to 2.8V, system power compatibility must be re-evaluated, along with verifying whether the LVCMOS output levels meet the load requirements.
2. SIT8208AI-G2-28E-62.500000X Substitution Conclusion
This model shares identical specifications with the T version described above, including the 2.8V supply voltage. The suffix "X" likely indicates differences in packaging or ordering codes, but electrical characteristics are consistent with the T variant. Its substitution feasibility is therefore the same as the T version: voltage mismatch remains the primary obstacle. The system supply must be compatible with 2.8V, and output levels must meet load requirements. If the suffix only denotes production batch or packaging variations, the T and X versions can be considered electrically equivalent—however, neither can directly replace the original 3.3V model.
