Crystals Procurement Notes

Verify the specific suffix code to confirm exact tolerance and stability ratings, as the XX placeholder indicates variable configurations within the 402F260XXCDR family. Ensure the selected variant matches the required frequency stability for the target application. Confirm package dimensions and mounting orientation against the specific datasheet revision prior to procurement.

Crystals Selection Notes

Select this component when a 26 MHz fundamental crystal with ±15 ppm stability is required in a small SMD form factor. Consider the 18 pF load capacitance requirement for circuit design compatibility. Evaluate thermal performance and aging characteristics if operating in high-stability environments compared to higher-grade alternatives.

Crystals Part Context

This part belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series offers various frequency codes and package options for industrial and consumer electronics. The 402F260XXCDR represents a standard surface-mount solution within this portfolio, distinct from the CA20/CA25 oscillator series which include integrated circuits.

Crystals Replacement Considerations

Direct substitutes include other 26 MHz crystals with identical 18 pF load capacitance and ±15 ppm stability in 4-SMD packages. Verify equivalent ESR values and drive level specifications to ensure circuit compatibility without redesign.
