1. SIT8208AI-G2-25E-62.500000X Substitution Conclusion
This part can serve as a conditional substitute. The key difference lies in the supply voltage, which is reduced from 2.8V in the original part to 2.5V, presenting a critical threshold for electrical compatibility. While both devices are identical in core functionality (62.5MHz, ±25ppm stability, LVCMOS output, enable control), package footprint, and power consumption, substitution is not universal. If the target board's power rail is a strict and non-adjustable 2.8V, this 2.5V device risks overvoltage damage or long-term reliability issues. Conversely, if the system operates at 2.5V or is compatible with 2.5V logic levels, this model is a direct drop-in replacement and offers the benefit of reduced system power consumption.
2. SIT8208AI-G2-25E-62.500000Y Substitution Conclusion
The substitution feasibility for this model is identical to the 'X' suffix part above: conditionally viable. A comparison confirms that all published key parameters for `SIT8208AI-G2-25E-62.500000Y` and `SIT8208AI-G2-25E-62.500000X` are exactly the same, including the 2.5V supply voltage, frequency, stability, output type, package, and current consumption. The suffix difference ('X' vs. 'Y') typically denotes non-technical identifiers such as manufacturing lot, internal code, or packaging quantity, with no impact on electrical performance. Therefore, the substitution logic and risk assessment remain unchanged. The core variance is still the operational voltage shift from 2.8V to 2.5V. Successful substitution hinges entirely on whether the target application's supply voltage matches or is compatible with this change.
