1. SIT8208AI-G1-18E-62.500000T Substitution Conclusion
The SIT8208AI-G1-18E-62.500000T can serve as a direct, drop-in replacement for the original SIT8208AI-G2-18E-62.500000T. Both parts are identical in all core electrical specifications—frequency, voltage, output type, functionality, and package footprint. The sole technical distinction is an improvement in frequency stability from ±25ppm in the original G2 version to ±20ppm in this G1 variant. Over the operating temperature range of -40°C to +85°C, the G1 device exhibits a smaller maximum frequency deviation from its nominal value. This enhancement provides higher timing accuracy and increased timing margin, representing a performance upgrade. Therefore, the substitution is not only feasible but also beneficial.
2. SIT8208AI-G1-18E-62.500000X Substitution Conclusion
The SIT8208AI-G1-18E-62.500000X is electrically and mechanically equivalent to the G1-T model described above, including its ±20ppm frequency stability. Consequently, it is also a valid replacement for the original G2 part. The only difference between these two G1 versions lies in the suffix "T" versus "X". This suffix typically denotes a factory calibration tolerance code or an internal manufacturing lot code. For end-use applications, there is no functional or parametric difference. However, the code may indicate variations in the supply chain source, factory calibration records, or minimum order packaging. When substituting directly, care should be taken to distinguish this code within the material management system.
