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 part can be considered a conditional substitute. The key difference from the original part (specified for 2.8V supply) is its 3.3V supply voltage. Direct replacement will cause malfunction or damage if the original circuit's power rail is fixed at 2.8V and cannot provide 3.3V. Conversely, if the system can supply 3.3V and the downstream load is compatible with 3.3V LVCMOS levels, substitution is viable as all other critical parameters—frequency, stability, package, and functionality—are identical.
2. SIT8208AI-G1-33E-62.500000Y Substitution Conclusion
This model's technical parameters are identical to the 'X' variant above (both are 3.3V supply). Therefore, the substitution conclusion is the same: replacement is possible provided the supply voltage is compatible. While the suffix 'Y' may relate to manufacturing lot, internal coding, or an undocumented minor characteristic (e.g., screening grade), the provided parameter list shows no electrical performance difference. Consequently, the practical substitution conditions are exactly the same as for the 'X' model.
