Procurement Notes

Verify that the specific suffix MAAE corresponds to the required ±30 ppm stability and 12 pF load capacitance specifications. Confirm that the 4-SMD no-lead package type matches the PCB footprint design. Ensure that the temperature range of -20°C to +70°C meets the operational environment requirements. Cross-reference the manufacturer's latest datasheet to confirm lead-free status and RoHS compliance before finalizing procurement orders.

Selection Notes

Select this component when a 25 MHz reference with moderate stability is required for cost-sensitive applications. The 12 pF load capacitance must match the oscillator circuit design to ensure accurate frequency operation. Consider the ±30 ppm tolerance against system timing requirements. The SMD form factor supports high-volume manufacturing. Evaluate thermal performance within the -20°C to +70°C range for environmental suitability.

Part Context

This part belongs to the QT532S series of surface-mount crystals from QST. The series offers various frequencies and stability options. The QT532S-25.000MAAE-T specifically targets 25 MHz applications requiring standard stability. It complements other variants like the MEEQ series which offer tighter tolerances. The series is designed for general-purpose timing needs in modern electronic devices.

Replacement Considerations

Direct substitutes may include other 25 MHz crystals with identical 12 pF load capacitance and 40 Ohm ESR. Verify pinout compatibility for the 4-SMD no-lead package. Check if alternative manufacturers offer components with matching ±30 ppm stability and similar physical dimensions to ensure mechanical fit.
