Crystals Procurement Notes

Verify current availability status as this component is listed as obsolete in official distributor records. Confirm end-of-life notifications with TXC Corporation prior to design finalization. Ensure replacement strategies are implemented if production continuity is required for long-term manufacturing cycles.

Crystals Selection Notes

Select this part only when specific 7.680 MHz timing is required with HC-49/US form factor constraints. Evaluate thermal requirements against the -20°C to +70°C operational limit. Consider alternative frequencies if system architecture allows flexibility to mitigate obsolescence risks associated with discontinued components.

Crystals Part Context

This crystal belongs to the 9B series from TXC Corporation, characterized by standard through-hole packaging. It serves as a fundamental frequency reference for digital logic circuits. The HC-49/US package remains a common industry standard for general-purpose timing applications despite the component's discontinued status.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the obsolete lifecycle status. Designers should consult TXC Corporation directly for recommended cross-references or equivalent active components that match the 7.680 MHz frequency and 18 pF load capacitance specifications.
