Procurement Notes

Verify the complete part number including suffixes against official QST documentation to ensure correct frequency and tolerance specifications. Confirm package dimensions and mounting requirements match the target PCB layout. Cross-reference datasheets for thermal characteristics and recommended soldering profiles to guarantee long-term reliability in final assemblies.

Selection Notes

Select this component when a 24 MHz reference is required in a compact 3.2x2.5mm footprint. Ensure the application circuit supports an 18 pF load capacitance to maintain accurate frequency output. Evaluate the ±30 ppm stability requirement against system timing constraints before integration into the design.

Part Context

This model belongs to the QT325G series of surface-mount quartz crystals from QST. The series offers various frequency options and stability grades within standardized small outline packages. These components are engineered for high-volume manufacturing processes and provide consistent performance across consumer and industrial electronics applications.

Replacement Considerations

Direct substitutes must match the 24 MHz frequency, 18 pF load capacitance, and 3.2x2.5mm package dimensions. Verify equivalent stability ratings and sealing technology to maintain circuit performance without redesign.
