Crystals Procurement Notes

This component is officially listed as obsolete or discontinued by the manufacturer. Verification of current availability requires checking distributor status directly, as supply may be limited to remaining stock or last-time buys. Ensure compatibility with existing PCB footprints before sourcing alternatives.

Crystals Selection Notes

Select this part only if the specific 19.6608 MHz frequency, 18 pF load capacitance, and HC-49/US form factor are mandatory for the design. Due to its obsolete status, engineers should evaluate pin-compatible or electrically equivalent replacements from other manufacturers that offer active production status and long-term supply agreements.

Crystals Part Context

The 9B series represents TXC Corporation's line of fundamental quartz crystals. This specific model belongs to the broader family of precision frequency components designed for cost-effective timing applications in consumer and industrial electronics, utilizing standard mounting technologies.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include LP19BF33CDT and LP19BF33CET from CTS-Frequency Controls. These alternatives are categorized as similar replacements but require verification of electrical parameters and mechanical fit.
