Alternative Part
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 2.5V Enable/Disable 4-SMD, No Lead
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 2.5V Enable/Disable 4-SMD, No Lead
1. SIT8208AI-G2-25E-62.500000X Substitution Conclusion
Substituting this part for the original model is not feasible. The key difference lies in the supply voltage, which is reduced from 3.3 V for the original to 2.5 V. Other critical parameters—frequency (62.5 MHz), frequency stability (±25 ppm), output type (LVCMOS/LVTTL), package (4-SMD), and current consumption (max 33 mA)—remain identical. If directly substituted in a 3.3 V system, the 2.5 V XO may be damaged due to overvoltage. Moreover, its output logic high level (approximately 2.5 V) could fall below the input high‑level threshold of a 3.3 V system (typically requiring >2.0 V, leaving insufficient margin), leading to signal compatibility issues or logic errors. Substitution is not recommended unless the system power supply and logic levels can be adapted to 2.5 V.
2. SIT8208AI-G2-25E-62.500000Y Substitution Conclusion
Substituting this model for the original is also not viable. The discrepancy is the same as described above: the supply voltage changes from 3.3 V to 2.5 V, while all other parameters—frequency, stability, output, package, and current—match the original. Direct voltage substitution risks supply mismatch (a 3.3 V supply could damage the 2.5 V device), and the reduced output level may cause incompatibility with 3.3 V receivers, compromising system reliability. Although the suffix changes from “Y” in the original to “Y” within the “25E” series, the parameter list shows no other variations. Thus, the voltage difference remains the core issue; substitution would require system‑level adjustments to both power supply and level translation.
