Procurement Notes

Verify the specific suffix 'AAV' against the manufacturer's current datasheet to confirm the exact load capacitance and temperature range specifications. Ensure that the 4-SMD no-lead footprint matches the target PCB design constraints. Confirm RoHS compliance status if required by regulatory standards for the end product assembly process.

Selection Notes

Select this component when a 40 MHz reference with ±30 ppm stability is required in a small form factor. Consider the 50 Ohm ESR value for oscillator circuit compatibility. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare load capacitance requirements with the host oscillator circuit design to ensure proper frequency accuracy.

Part Context

This part belongs to the QT216S series of surface-mount crystals from QST Products. The series offers various frequencies and package options for timing applications. The 40 MHz variant provides a standard clock frequency for digital systems. The no-lead design facilitates automated assembly processes in high-volume manufacturing environments.

Replacement Considerations

Cross-reference with other 40 MHz crystals featuring 4-SMD no-lead packages and similar electrical parameters. Verify pinout compatibility and mechanical dimensions before substitution. Ensure equivalent frequency stability and load capacitance specifications are met by alternative sources.
