1. SIT8208AI-G2-28E-62.500000Y Substitution Conclusion
Compared with the original part SIT8208AI-G2-25E-62.500000T, the SIT8208AI-G2-28E-62.500000Y differs only in its supply voltage, which is changed from 2.5 V to 2.8 V. All other parameters—including frequency (62.5 MHz), output type (LVCMOS/LVTTL), frequency stability (±25 ppm), package dimensions, and current characteristics—remain identical. When considering substitution, system power compatibility must be evaluated: if the original design is based on a 2.5 V supply, direct replacement may cause the device to malfunction due to voltage mismatch, or its output levels may fail to meet LVCMOS/LVTTL specifications, leading to timing errors or device damage. This substitution is feasible only if the system can provide a 2.8 V rail or be adapted via a power‑adjustment circuit; otherwise, compatibility risks will arise.
2. SIT8208AI-GF-25E-62.500000T Substitution Conclusion
Relative to the original part SIT8208AI-G2-25E-62.500000T, the SIT8208AI-GF-25E-62.500000T offers improved frequency stability (±10 ppm versus ±25 ppm). All other parameters—supply voltage (2.5 V), frequency (62.5 MHz), output type, package size, and current characteristics—are exactly the same. The substitution will deliver higher timing accuracy, making it suitable for applications with stricter clock‑stability requirements, such as high‑speed communications or precision measurement systems. Electrical and mechanical compatibility is fully maintained with the original design. Note that cost may increase due to the enhanced performance; if the original application does not demand high stability (e.g., general consumer electronics), the substitution may not be cost‑effective. From a functional standpoint, however, this is a seamless upgrade that requires no additional design changes.
