1. SIT8208AI-G2-33E-62.500000T Substitution Conclusion
This part cannot serve as a direct replacement for the original component. The key discrepancy lies in its operating voltage of 3.3V, compared to the original's 2.8V. If the target system's power rail is strictly 2.8V, this device may fail to start up or output invalid logic levels. Conversely, if the system supply is 3.3V, directly replacing the original 2.8V device could subject it to overvoltage and potential damage. While both devices are identical in frequency, package, frequency stability (±25ppm), and functionality (enable/disable), the voltage mismatch is a fundamental incompatibility. System supply voltage compatibility must be rigorously verified prior to any substitution attempt.
2. SIT8208AI-G2-33E-62.500000X Substitution Conclusion
This model is also not a direct substitute for the original component. Its substitution feasibility is identical to that of the "T" version described above. There are no differences between the "X" and "T" suffixes in critical parameters such as voltage, frequency, stability, package, or current consumption. The suffix variation ("X" vs. "T") likely relates only to order packaging, labeling, or minimum order quantity and does not affect electrical specifications. The core obstacle remains the 3.3V operating voltage versus the original's 2.8V. The primary assessment must focus on the actual system supply voltage to evaluate substitution risk. The electrical substitution conclusion for this part aligns completely with that of the "T" version.
