1. SIT8208AI-G2-28E-62.500000Y Substitution Conclusion
This device is identical to the original part in package dimensions, frequency, output type, and functionality. The key difference lies in the supply voltage: 2.8V for this model versus 2.5V for the original. Direct substitution requires verifying that the target system’s power rail is compatible with 2.8V. Otherwise, voltage mismatch may cause abnormal clock signal levels or unstable device operation. If the power supply meets the requirement, the part can be dropped in directly, though slight variations in power consumption and signal levels should be considered for sensitive circuits.
2. SIT8208AI-GF-25E-62.500000T Substitution Conclusion
This model is fully compatible with the original in package, frequency, voltage, and functionality. A key improvement is the frequency stability, enhanced from ±25ppm to ±10ppm. It offers higher timing accuracy and is suitable for applications with stricter requirements on clock jitter and long-term stability, such as high-speed communications or precision measurement. The device is a direct electrical and mechanical replacement for the original and provides superior performance. However, the potential cost premium for improved stability should be evaluated.
