Procurement Notes

Verify the manufacturer designation carefully, as the QT252S series is produced by both QST and TXC Corporation. Ensure the specific suffix matches the required load capacitance and stability specifications. Confirm availability through authorized distributors, as supply status may vary by region. Cross-reference the datasheet to ensure compatibility with your circuit design requirements before procurement.

Selection Notes

Select this component when a 19.2 MHz reference signal is required in space-constrained designs. The 8 pF load capacitance must match the oscillator circuit's external capacitor values. Consider the ±30 ppm stability for applications requiring moderate precision. The SMD form factor supports automated assembly processes suitable for high-volume manufacturing environments.

Part Context

This part belongs to the QT252S series of seam seal crystals. Similar variants include different frequencies such as 30.000 MHz or 38.000 MHz, and other load capacitances like 12 pF. The series offers various mounting options and stability grades to suit diverse electronic applications ranging from consumer goods to industrial machinery.

Replacement Considerations

Direct substitutes include other 19.2 MHz crystals with identical 4-SMD dimensions and 8 pF load capacitance. Verify that alternative parts meet the same ±30 ppm stability and ESR requirements. Check if the replacement component supports the required operating temperature range of -20°C to +70°C.
