Crystals Procurement Notes

Verify the specific suffix 'CKT' or 'KR' against the manufacturer's current datasheet to confirm packaging and availability status, as distribution channels may list varying part statuses. Ensure the required load capacitance matches the circuit design before procurement. Check for lead time variations due to manufacturing updates.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with tight ±10 ppm stability is required. The 8 pF load capacitance must align with the oscillator circuit design. Consider the 4-SMD package size for PCB space constraints. Verify the operating temperature range meets the environmental requirements of the target application.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series provides various frequencies and package options for general-purpose timing needs. The 402F5401XIKR specifically targets applications requiring moderate stability in a small form factor. It is distinct from higher-stability or different-package variants within the same family.

Crystals Replacement Considerations

Direct substitutes include other 54 MHz SMD crystals with 8 pF load capacitance and similar ESR. Verify pin compatibility and mechanical dimensions for direct replacement. Cross-reference with other manufacturers offering equivalent fundamental frequency and stability specifications.
