Crystals Procurement Notes

Verify the specific suffix 'IKT' against official CTS documentation to confirm packaging and tape specifications. Ensure compatibility with existing load capacitance values in the target circuit design. Confirm that the ±20ppm stability meets the system requirements. Check for any recent lifecycle status changes or alternative recommendations from the manufacturer before finalizing procurement plans.

Crystals Selection Notes

Select this component when a 40 MHz fundamental crystal is required with ±20ppm stability. The 8pF load capacitance must match the oscillator circuit design. Consider the -40°C to 85°C temperature range for industrial applications. The 60 Ohm ESR should be compatible with the driving capability of the host microcontroller or oscillator IC. Verify package dimensions fit the PCB footprint constraints.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. The series offers various frequencies and packages optimized for space-constrained designs. The 402F40022IKT specifically provides a 40 MHz output in a 2.00mm x 1.60mm footprint. It is distinct from other series like the 416, which may have different electrical characteristics or package sizes.

Crystals Replacement Considerations

Direct substitutes include parts with identical 40 MHz frequency, 8pF load capacitance, and 4-SMD 2x1.6mm package. Verify ESR and temperature range compatibility. Cross-reference with CTS internal cross-reference lists for exact pin-compatible alternatives.
