Procurement Notes

Verify the suffix codes against official QST documentation to confirm exact tolerance and temperature range specifications. Ensure the glass-sealed package type matches the thermal requirements of the target assembly process. Cross-reference the load capacitance value with the host circuit design to maintain frequency accuracy.

Selection Notes

Select this component when a compact, glass-sealed crystal is required for 41.6 MHz applications. Consider the ±30 ppm initial tolerance and ±50 ppm total stability limits relative to system timing budgets. Evaluate the 10 pF load capacitance compatibility with the oscillator circuit's input and output capacitance parameters.

Part Context

This part belongs to the QT325G series of quartz crystals produced by QST. The series offers various frequency options within a standardized 3.2x2.5 mm glass-sealed package. Different suffixes denote variations in frequency tolerance, stability, and operating temperature ranges, allowing customization for specific electronic design needs.

Replacement Considerations

Direct substitutes must match the 41.6 MHz frequency, 10 pF load capacitance, and 3.2x2.5 mm glass-sealed package dimensions. Verify equivalent electrical characteristics such as ESR and stability ratings. Consult manufacturer cross-reference lists for approved alternative part numbers.
