Crystals Procurement Notes

This specific part number is officially discontinued and no longer manufactured by TXC Corporation. Verification of availability should focus on identifying authorized substitute components or alternative manufacturers offering equivalent electrical specifications. Procurement strategies must account for end-of-life status, prioritizing functional replacements that match the required frequency, load capacitance, and package dimensions to ensure circuit compatibility without redesign.

Crystals Selection Notes

When selecting a replacement, prioritize components matching the 8 MHz frequency, 18 pF load capacitance, and HC-49/US form factor. Verify that the substitute meets the ±10 ppm stability requirement and operates within the -20°C to +70°C range. Ensure the new component's ESR remains compatible with the target oscillator circuit design to maintain signal integrity and startup reliability.

Crystals Part Context

The 9B series represents TXC Corporation's line of standard through-hole quartz crystals. This model belongs to a family known for cost-effective frequency control solutions. The HC-49/US package is widely adopted in legacy and current designs for its mechanical stability and ease of automated or manual insertion into printed circuit boards.

Crystals Replacement Considerations
