Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to ensure correct load capacitance and temperature range specifications. Confirm package dimensions and terminal availability prior to integration. Cross-reference part numbers with authorized distributors to validate authenticity and supply chain integrity for production requirements.

Selection Notes

Select this component when a 20 MHz reference signal is required in a low-profile surface-mount format. Ensure circuit design accommodates the specified 18 pF load capacitance for accurate frequency alignment. Evaluate thermal constraints to confirm compatibility with the -20°C to +70°C operational window for the intended application environment.

Part Context

This crystal belongs to the QT532S series, which represents a family of small-footprint resonators designed for high-volume consumer and industrial electronics. The series emphasizes miniaturization while maintaining standard electrical characteristics compatible with common oscillator circuits and microcontroller architectures requiring precise timing references.

Replacement Considerations

Direct substitutes include the QT532S-20.000MAHJ-T from QST Products, LLC, which shares identical electrical parameters and physical dimensions. Verify pinout compatibility and mounting orientation before substitution to ensure seamless integration into existing board designs without rework.
