Procurement Notes

Verify the specific suffix 'AAI' against official QST documentation to confirm the exact load capacitance and tolerance specifications. Ensure compatibility with the target circuit's drive level requirements and thermal environment before finalizing procurement decisions.

Selection Notes

Select this component when a 37.4 MHz reference is required in a minimal footprint SMD package. Consider the ±30 ppm tolerance limits relative to system timing accuracy needs. Evaluate the 16 pF load capacitance requirement against the oscillator circuit design parameters.

Part Context

This part belongs to the QT161S series of surface-mount crystals from QST. The series offers various frequency options in a standardized small outline package format, designed for integration into modern electronic assemblies requiring reliable timing sources.

Replacement Considerations

Cross-reference with other 37.4 MHz crystals in 1.6x1.2mm packages. Verify equivalent electrical parameters including load capacitance and frequency tolerance before substitution.
