Original Part
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 2.8V Enable/Disable 4-SMD, No Lead
Alternative Part
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 3.3V Enable/Disable 4-SMD, No Lead
62.5 MHz XO (Standard) LVCMOS, LVTTL Oscillator 3.3V Enable/Disable 4-SMD, No Lead
1. SIT8208AI-G1-33E-62.500000X Substitution Conclusion
This device offers identical frequency (62.5 MHz), frequency stability (±20 ppm), package (4-SMD), and output logic (LVCMOS/LVTTL) compared to the original part. The key difference lies in its supply voltage of 3.3 V, whereas the original part operates at 2.8 V. Direct substitution without consideration may result in malfunction or damage due to voltage mismatch. If the target system’s power design is compatible with 3.3 V and the downstream load can accept the corresponding logic levels, this device can serve as a functional replacement. Otherwise, a reassessment of the power supply circuit or level‑shifting requirements is necessary.
2. SIT8208AI-G1-33E-62.500000Y Substitution Conclusion
This model is identical to the X variant in all listed parameters, including 3.3 V supply, 62.5 MHz frequency, and package dimensions. The substitution feasibility conclusion remains the same: the voltage difference is the only critical distinction. Direct replacement of the original 2.8 V part without modifying the system power supply carries risk. If the system can accommodate 3.3 V operation and the signal levels are compatible, functional substitution is achievable; otherwise, circuit modifications are required.
