Crystals Procurement Notes

This component is officially listed as obsolete or end-of-life by TXC Corporation. Availability is restricted to existing stock or secondary market sources. Verify datasheet revisions and confirm RoHS compliance status directly with suppliers before procurement, as manufacturing changes may have occurred prior to discontinuation.

Crystals Selection Notes

Engineers should identify alternative components from the same product family or newer generations that meet identical electrical specifications. Ensure replacement parts match the required load capacitance, ESR, and physical dimensions. Validate that substitute crystals support the target operating temperature range and frequency stability requirements for the intended application.

Crystals Part Context

The 9C04000131 belongs to the broader 9C series of quartz crystals manufactured by TXC Corporation. This series typically includes various frequencies and package options for standard timing needs. As an obsolete item, it represents legacy inventory within the company's historical product lineup rather than current active production lines.
