Crystals Procurement Notes

Verify that the replacement part matches the specific 25 MHz frequency, 20 pF load capacitance, and 30 Ohm ESR parameters. Confirm the HC-49/US footprint compatibility and ensure the supplier provides documentation confirming RoHS3 compliance. Check the operating temperature range requirements against the -20°C to +70°C specification to guarantee reliable performance in the target environment.

Crystals Selection Notes

Select this component when a standard 25 MHz reference is required for surface-mount designs. The HC-49/US form factor allows for easy integration into existing layouts. Ensure the application does not require higher frequency stability than ±50 ppm or wider industrial temperature ranges beyond the specified limits.
