1. SIT8208AI-GF-18E-62.500000T Substitution Conclusion
This model can serve as a direct replacement for the original part. The key improvement lies in its frequency stability, which has been enhanced from ±20ppm to ±10ppm. Under variations in temperature, voltage, and other environmental conditions, this results in higher output frequency accuracy and better system timing margin, constituting a performance upgrade. All other critical parameters—including frequency, supply voltage, output logic, package dimensions, and functionality—remain fully identical. Therefore, the substitution carries no risk in terms of electrical or mechanical compatibility, and a higher reliability level is expected.
2. SIT8208AI-GF-18E-62.500000X Substitution Conclusion
This model is also suitable for direct replacement of the original part. The primary difference, similarly, is the improved frequency stability of ±10ppm, and its technical specifications are completely aligned with the above “T” suffix variant. The distinction between the “X” and “T” suffixes typically relates to tape-and-reel packaging or order configuration and does not affect electrical performance. While the substitution meets the original design requirements and offers higher frequency accuracy, it is necessary to verify that the packaging and assembly compatibility of the “X” suffix variant align with the original supply chain requirements.
