1. SIT8208AI-G1-25E-62.500000T Substitution Conclusion
This part is not a direct drop-in replacement for the original component. The primary discrepancy lies in its supply voltage of 2.5V, compared to the original's 3.3V. If used directly within the original 3.3V power rail design, the device may fail to operate correctly due to insufficient voltage. Its output levels would likely not meet the logic threshold requirements for LVCMOS/LVTTL in a 3.3V system, potentially causing signal integrity or timing issues. While both devices share identical frequency, stability, package, and functionality, the voltage mismatch results in electrical incompatibility. Therefore, substitution is only feasible if the power supply is concurrently adjusted to 2.5V.
2. SIT8208AI-G1-25E-62.500000X Substitution Conclusion
Similarly, this model cannot directly replace the original part. The critical difference is again the 2.5V supply voltage versus the original 3.3V. The operating logic levels are incompatible with the original design. Forcing its use in a 3.3V system risks insufficient output swing, logic misinterpretation, or potential device damage. Although other parameters—including frequency, stability, package footprint, and current characteristics—are consistent with the original, the voltage disparity dictates that a power supply redesign is mandatory for substitution. Direct replacement without modifying the system voltage is not viable.
