Crystals Procurement Notes

Verify manufacturer authenticity as the part is listed as obsolete or end-of-life by TXC Corporation. Confirm availability from authorized distributors only. Ensure compliance with current environmental regulations regarding lead-free components. Check datasheet revisions for any parameter updates before integration into new designs.

Crystals Selection Notes

Select this component when an 8 MHz fundamental mode crystal is required with HC-49/US mounting compatibility. Consider the ±30 ppm stability requirement against system timing tolerances. Evaluate the 120 Ohm ESR against oscillator circuit drive levels. Verify that the -40°C to +85C temperature range meets operational environment specifications.

Crystals Part Context

This crystal belongs to the AS series of fundamental mode quartz crystals produced by FTS/TXC. It utilizes the standard HC-49/US metal can package, widely used in legacy and industrial electronics. The part represents a specific frequency variant within a broader family of resonators designed for general-purpose timing applications.

Crystals Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. As the product lifecycle status is marked as Obsolete/EOL, direct replacements must be sourced from alternative manufacturers offering compatible electrical parameters and mechanical dimensions.
