Procurement Notes

Verify the specific suffix 'MAAV-T' against the manufacturer's current datasheet to ensure alignment with the required frequency tolerance and temperature range specifications. Confirm that the 4-SMD footprint dimensions match the target PCB layout constraints. Check for any recent updates to the RoHS3 compliance status or material declarations prior to finalizing procurement orders to ensure regulatory adherence.

Selection Notes

Select this component when a 32 MHz reference signal is required with moderate stability requirements. The 8 pF load capacitance must match the oscillator circuit design parameters to ensure accurate frequency output. Consider the 80 Ohm ESR value for drive level sensitivity. Ensure the operating environment remains within the specified -20°C to +70°C range to maintain the guaranteed ±30 ppm stability.

Part Context

This part belongs to the QT161S series of thin-film quartz crystals from QST. These components are engineered for high-frequency applications where small form factors are critical. The series offers various frequency options and tolerance grades, with this specific model providing a standard 32 MHz output optimized for general-purpose digital timing applications in consumer and industrial hardware.

Replacement Considerations

Direct substitutes may include other 32 MHz SMD crystals with identical 4-SMD footprints and 8 pF load capacitance. Verify that alternative parts meet the same ±30 ppm stability and -20°C to +70°C temperature range requirements. Ensure the replacement component has comparable ESR characteristics to maintain circuit oscillation reliability.
