Crystals Procurement Notes

This component is officially designated as obsolete by the manufacturer. Availability is restricted to existing stock or surplus channels only. Verify authenticity carefully when sourcing from third-party distributors. Confirm that the HC-49/S footprint matches your PCB design requirements before procurement.

Crystals Selection Notes

Engineers should evaluate alternative active oscillators or modern crystal packages due to the discontinued status of this part. Ensure the 20 pF load capacitance aligns with the host circuit's resonant requirements. Consider thermal stability constraints imposed by the limited -20°C to +70°C operating range for critical applications.

Crystals Part Context

The 9C25077009 represents a legacy passive crystal component from TXC Corporation's 9C series. It serves as a basic timing element relying on external oscillator circuits rather than providing an integrated output signal. Its discontinuation reflects industry shifts toward smaller surface-mount technologies and integrated oscillator solutions.
