1. SIT8208AI-G2-28E-62.500000T Substitution Conclusion
This part can serve as a direct drop-in replacement for the original device, provided the target system’s power supply design can deliver 2.8V instead of the original 2.5V. The only significant difference between the two is the supply voltage (2.8V vs. 2.5V); all other key parameters—including frequency (62.5 MHz), stability (±25 ppm), output type (LVCMOS/LVTTL), package footprint, and current characteristics—are identical. Voltage compatibility must be verified against the system’s power rails. If the system can support 2.8V or has adjustment headroom, the substitution will not affect electrical performance or timing behavior. However, if the system is limited to a fixed 2.5V supply, voltage mismatch may lead to operational issues or reliability risks.
2. SIT8208AI-G2-28E-62.500000X Substitution Conclusion
This variant is also a feasible replacement, with the same voltage difference (2.8V vs. 2.5V) as the primary distinction. All other specifications—frequency, stability, package, and current ratings—match the original part. When substituting, ensure the system power rail can meet the 2.8V requirement; otherwise, a power design adjustment is necessary. Note that the suffix “X” may relate to specific test conditions, temperature range, or production lot. It is advisable to review the detailed SiTime datasheet to confirm any unlisted variations, such as temperature performance or quality grading. However, based solely on the given parameters and assuming system voltage compatibility, direct substitution is viable.
