Procurement Notes

Verify the specific suffix 'T' confirms the ±30 ppm stability rating and glass-seal type. Ensure the load capacitance requirement of the target circuit matches the 8 pF specification. Confirm the operating temperature range aligns with the -40°C to +85°C commercial grade. Cross-reference the pinout and soldering profile with the official datasheet to prevent assembly defects.

Selection Notes

Select this component when a stable 53.89194 MHz reference is required in space-constrained designs. The glass seal offers superior humidity resistance compared to standard epoxy packages. Consider the 8 pF load capacitance compatibility with the oscillator circuit. Evaluate the ±30 ppm tolerance against system jitter requirements.

Part Context

This part belongs to the QT325G series of surface-mount crystals from QST. The series is characterized by its compact 3.2x2.5 mm package and robust glass-sealing technology. It serves as a critical timing element in modern electronics where reliability and size are paramount.

Replacement Considerations

Direct substitutes must match the 53.89194 MHz frequency, 8 pF load capacitance, and ±30 ppm stability. Verify package dimensions and mounting style compatibility. Check if alternative manufacturers offer equivalent glass-sealed variants with identical thermal characteristics.
