Crystals Procurement Notes

Verify the specific suffix configuration against the official CTS datasheet to ensure compatibility with required load capacitance and tolerance levels. Confirm that the 4-SMD package dimensions align with the target PCB footprint constraints. Check current availability status as supply conditions may vary. Ensure that the operating temperature range meets the environmental requirements of the final application. Cross-reference the RoHS3 compliance status with project regulatory standards.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required with tight ±10ppm stability. The 8pF load capacitance must match the oscillator circuit design specifications. Consider the 100 Ohm ESR value for drive level sensitivity. The surface mount form factor is ideal for space-constrained designs. Evaluate the -20°C to +70°C temperature range against operational extremes.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series offers various frequency options and package sizes for general-purpose timing needs. The 402F20011CKT specifically addresses the demand for 20 MHz reference frequencies in SMD formats. It shares common design principles with other members of the 402 family regarding mounting and electrical characteristics.

Crystals Replacement Considerations

Direct substitutes include the 402F200XXCKT variant, though it exhibits ±15ppm stability rather than ±10ppm. Verify if the looser tolerance is acceptable for the specific application. Other 20 MHz 4-SMD crystals from different manufacturers require careful evaluation of pinout, load capacitance, and ESR parameters to ensure functional equivalence.
