Crystals Procurement Notes

Verify the specific suffix requirements against the manufacturer's official datasheet to ensure correct load capacitance and tolerance specifications. Confirm RoHS compliance status and lead-free characteristics prior to procurement. Check for any recent product discontinuance notifications or lifecycle changes directly from TXC Corporation documentation to avoid supply chain disruptions during production planning.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with 20 pF load capacitance is required for surface-mount designs. Ensure the application environment remains within the specified -20°C to +70°C operational range. Verify that the circuit design accommodates the 50 Ohm ESR and 100 uW drive level constraints to prevent frequency instability or crystal damage during operation.

Crystals Part Context

This part belongs to the TXC 7A series of fundamental quartz crystals. It serves as a passive timing element distinct from active oscillators, requiring an external oscillator circuit within the host device. The 7A series is characterized by its small form factor and suitability for consumer electronics and industrial control systems where precise frequency reference is critical.

Crystals Replacement Considerations

Consult the official TXC Corporation substitution guide for verified alternative part numbers. Cross-reference load capacitance, frequency tolerance, and physical dimensions to ensure mechanical and electrical compatibility without modifying the existing circuit design.
