Procurement Notes

Verify the specific suffix AAV against the manufacturer's current datasheet to confirm exact electrical parameters and packaging specifications. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the part number with authorized distributors to obtain official documentation and avoid counterfeit components.

Selection Notes

Select this component when a 32 MHz frequency is required with moderate stability. The 8 pF load capacitance suits circuits with standard stray capacitance. Consider the 60 Ohm ESR for startup performance. Verify that the 3.2x2.5mm footprint fits the PCB layout constraints. Compare against alternatives if tighter frequency tolerance or different package sizes are needed.

Part Context

This part belongs to the QT325G series of surface-mount crystals from QST. The series offers various frequencies and package options for general-purpose timing needs. The 32.000 variant specifically targets common clock speeds for microprocessors and communication modules. It represents a standard solution for cost-sensitive designs requiring reliable frequency generation.

Replacement Considerations

Direct substitutes include other 32 MHz SMD crystals with matching 8 pF load capacitance and similar physical dimensions. Verify ESR values and frequency stability tolerances match the original design requirements. Check pinout compatibility if using alternative manufacturers' packages.
