Procurement Notes

Verify the manufacturer designation, as this part is produced by TXC Corporation. Confirm the specific suffix 'BBK' corresponds to the required ±50 ppm stability and -20°C to +70°C temperature range. Ensure the 4-pin SMD footprint matches the PCB layout requirements. Check for end-of-life status or discontinuance notifications prior to finalizing procurement plans.

Selection Notes

Select this component when a 14.31818 MHz reference is required for NTSC video or similar applications. Choose based on the ±50 ppm stability requirement and the specific -20°C to +70°C operational environment. Consider the 4-pin CSMD form factor for space-constrained designs. Compare against other variants in the QT532S series if different temperature ranges or tolerances are needed.

Part Context

This part belongs to the QT532S series of surface-mount crystals. The series offers various frequencies and stability options. The QT532S-14.31818MBBK-T specifically targets applications requiring the standard 14.31818 MHz frequency. It is distinct from through-hole or larger package alternatives within the broader product line.

Replacement Considerations

Public confirmed substitute part numbers include QT532S-14.31818MAHJ-T. Verify that the alternative maintains identical frequency, load capacitance, and stability specifications before substitution.
