1. 656L38D4C3T Substitution Conclusion
The 656L38D4C3T can directly replace the original part 656L38D3C3T, as both share identical key electrical parameters (frequency, voltage, output type, function, and package dimensions). The only difference is an improved frequency stability from ±50ppm to ±30ppm. The substitute part offers higher frequency accuracy under variations in temperature and voltage, representing a performance upgrade. This substitution will not introduce compatibility issues with the existing circuit design and will instead enhance system timing stability.
2. 656V38D4C3T Substitution Conclusion
The 656V38D4C3T matches the original part in basic parameters (frequency, voltage, output, and package), with frequency stability also specified as ±30ppm. However, the prefix changes from "L" to "V". Although the datasheet may not indicate a difference, in CTS’s part numbering scheme, "V" typically denotes a wider operating temperature range or a different internal architecture. If the actual datasheet confirms that the temperature range covers the requirements of the original part, direct substitution is acceptable. Otherwise, verify that the temperature characteristics meet the application environment to avoid performance mismatch under extreme temperatures.
