1. SIT8208AI-G2-28E-62.500000T Substitution Conclusion
Direct substitution is not recommended. The primary difference between this part and the original model lies in the supply voltage, which has changed from 2.5 V to 2.8 V. If the target system’s power rail is strictly designed for 2.5 V, the supply mismatch may prevent the oscillator from operating properly or cause it to exceed its rated operating conditions, thereby compromising clock signal integrity and overall system reliability. In all other aspects—frequency, stability, package, output logic, and functionality—the two devices are identical. Unless the target system’s power design can accommodate or be adjusted to 2.8 V supply, direct substitution should be avoided.
2. SIT8208AI-G2-28E-62.500000X Substitution Conclusion
Direct substitution is not feasible. The key distinction between this model and the original is again the critical supply voltage parameter (2.8 V vs. 2.5 V). Replacing the original with this device would introduce power compatibility issues, potentially leading to under‑voltage operation or mismatched output levels with the input requirements of downstream ICs. Although the suffix “X” likely indicates identical temperature range or packaging, and all other specifications—including frequency, stability, package dimensions, and interface type—are exactly the same, the fundamental voltage difference precludes its use as a drop‑in replacement without modifying the power supply design.
