Procurement Notes

Verify the specific suffix 'AAV' against the manufacturer's current datasheet to confirm load capacitance and ESR specifications. Ensure the operating temperature range of -20°C to 70°C aligns with your application requirements. Confirm package dimensions match your PCB footprint constraints.

Selection Notes

Select this component when a 33.333 MHz clock source is required in a space-constrained surface-mount design. The ±30 ppm stability suits general-purpose timing applications. Consider the 8 pF load capacitance compatibility with the oscillator circuit's input capacitance to ensure accurate frequency performance.

Part Context

This part belongs to the QT325G series of small-size SMD crystals from QST. The series offers various frequencies with standardized 3.2x2.5mm packages. The 'QT325G' designation indicates the form factor and mounting type, while the numeric suffix specifies the exact frequency.

Replacement Considerations

Direct substitutes must match the 33.333 MHz frequency, 8 pF load capacitance, 3.2x2.5mm package, and ±30 ppm stability. Verify equivalent electrical parameters such as ESR and drive level before substitution.
