Crystals Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to existing stock or secondary market sources. Verify end-of-life status and lifecycle notifications before integration into new designs. Sourcing may require lead time adjustments due to limited supply chains.

Crystals Selection Notes

Engineers should identify active replacement components from the same manufacturer family or compatible third-party equivalents. Ensure substitute parts match the 4 MHz frequency, 30 pF load capacitance, and HC-49/US footprint requirements. Validate thermal performance and stability specifications against original design constraints.

Crystals Part Context

The 9C04000008 belongs to the 9C series of crystals manufactured by TXC Corporation. This series typically includes various frequencies and package types for standard electronic applications. As an obsolete item, it represents legacy inventory no longer in active production cycles.

Crystals Replacement Considerations

Public confirmed substitutes include generic 4 MHz HC-49/US crystals from other manufacturers. Specific cross-reference data requires consultation with distributor catalogs for current active alternatives.
