1. SIT8208AI-G2-25E-62.500000X Substitution Conclusion
Not a direct replacement. While this model matches the original (3.3V) in frequency, package, footprint, stability, and enable function, the critical difference lies in its supply voltage of 2.5V, compared to the 3.3V required by the original. If directly substituted into a circuit designed for 3.3V, the oscillator risks damage due to supply voltage exceeding its rating. Even if it operates, its LVCMOS output high level (approximately 2.5V) may fail to meet the logic-high input threshold of downstream 3.3V devices, resulting in signal level incompatibility and communication failure.
2. SIT8208AI-G2-25E-62.500000Y Substitution Conclusion
Not a direct replacement. This model shares the same situation as the X variant above. The primary and only electrical difference from the original model is likewise the supply voltage of 2.5V (original: 3.3V). Based on the provided parameters, the Y model shows no electrical or packaging differences from the X model. The suffix variation likely indicates lot number, custom code, or internal marking, but does not alter its fundamental characteristic as a 2.5V device. Using it in a 3.3V system would similarly introduce voltage mismatch issues affecting device reliability and signal integrity, thus direct substitution is not feasible.
