Procurement Notes

Verify the complete part number including suffixes such as METE-T against official QST documentation to ensure correct tolerance, packaging, and compliance specifications. Confirm RoHS status and lead-free requirements with the supplier. Cross-reference datasheet parameters like ESR and load capacitance with circuit design requirements before procurement to avoid compatibility issues.

Selection Notes

Select this component when a 32 MHz fundamental frequency with ±10 ppm tolerance is required for applications operating between -30°C and +85°C. Ensure the circuit design accommodates the 12 pF load capacitance and 60 Ohm ESR characteristics. Consider the 2.5x2.0 mm footprint for board layout constraints and verify mounting type compatibility with automated assembly processes.

Part Context

This part belongs to the QT252S series of surface-mount crystals from QST. The series offers various frequencies and tolerances within a standardized 2.5x2.0 mm package. The METE-T suffix indicates specific tolerance, stability, and packaging configurations unique to this variant within the broader product line.

Replacement Considerations

Direct substitutes include other 32 MHz SMD crystals with identical 12 pF load capacitance, ±10 ppm tolerance, and similar physical dimensions. Verify pinout compatibility and electrical parameters such as ESR and stability ranges before substitution.
