Crystals Procurement Notes

This component is officially designated as obsolete or end-of-life by the manufacturer. Verification of current availability requires direct consultation with authorized distributors or inventory holders. Procurement should focus on identifying remaining stock sources rather than new production orders. Ensure that any acquired units are verified for authenticity and storage conditions prior to implementation in design projects.

Crystals Selection Notes

Engineers selecting this part must account for its discontinued status when planning long-term production cycles. Alternative components within the same frequency and package family may require circuit re-evaluation due to potential differences in load capacitance or ESR specifications. Designers should prioritize parts with confirmed supply chain continuity for future manufacturing phases.

Crystals Part Context

The 9B series represents a line of through-hole quartz crystals from TXC Corporation, widely used in legacy and industrial electronics. This specific model provides a precise 22.1184 MHz reference, commonly utilized in baud rate generation for serial communication protocols. The HC-49/US package remains a standard form factor for cost-sensitive and space-flexible designs.

Crystals Replacement Considerations

Direct substitutes include 9B-22.1184MAAY-B and 9B-22.1184MAAE-B. These alternatives offer similar frequencies but differ in load capacitance (7 pF vs 20 pF) and stability ratings. Circuit adjustments may be necessary if replacing with these variants due to capacitive loading changes.
