Procurement Notes

Verify manufacturer authenticity through official channels or authorized distributors. Confirm that the part number matches exactly QT532G-14.7456MAHJ-T to ensure correct frequency and tolerance specifications. Check datasheet revisions for any updates on mechanical dimensions or electrical characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a 14.7456 MHz reference is required in space-constrained designs. Ensure circuit layout accommodates the 5.0x3.2mm footprint. Verify that the 18pF load capacitance aligns with the oscillator circuit requirements. Consider the ±30ppm tolerance if higher precision is needed for specific communication protocols.

Part Context

This part belongs to the QT532G series of quartz crystals from QST. The series offers various frequencies within the 5.0x3.2mm package format. It serves as a passive timing element distinct from active oscillators, requiring an external oscillator circuit or MCU internal oscillator to function.

Replacement Considerations

Direct substitutes must match the 14.7456 MHz frequency, 18pF load capacitance, and 5.0x3.2mm package size. Verify tolerance and temperature range compatibility. Cross-reference with other manufacturers offering similar SMD crystals if QST supply is limited.
