1. Substitution Conclusion for SIT8208AI-G1-25E-62.500000T
Based on technical parameter comparison, the SIT8208AI-G1-25E-62.500000T can fully replace the original model (G2 version). The core difference lies only in frequency stability: the G1 version offers ±20ppm, which is superior to the ±25ppm of the original G2 version. The G1 provides higher frequency accuracy and timing consistency under variations in temperature, voltage, and other environmental conditions. All other key parameters—including frequency (62.5 MHz), supply voltage (2.5V), output type (LVCMOS/LVTTL), package dimensions (2.7×2.4mm), and enable function—are identical. The G1 version is directly compatible in terms of electrical and mechanical characteristics, and its improved stability represents a positive upgrade replacement.
2. Substitution Conclusion for SIT8208AI-G1-25E-62.500000X
The SIT8208AI-G1-25E-62.500000X is technically identical to the G1-25E-62.500000T, including the ±20ppm stability specification. The only difference is the suffix “X” versus “T,” which typically indicates minor variations in factory frequency tolerance or test conditions, with no distinction in actual electrical characteristics, package, or functionality. According to SiTime’s naming convention, such suffix differences do not affect key performance and are generally related to production lot or calibration standards. This model is also a feasible replacement for the original G2 version, with stability superior to the original. However, attention should be paid to the suffix difference, as it may involve updates to supply chain labeling or documentation. It is recommended to verify that the specific lot specifications meet end-application consistency requirements.
