Crystals Procurement Notes

Verify the specific orderable part number against manufacturer documentation to ensure correct suffix alignment. Confirm that the required frequency tolerance and load capacitance match the design specifications. Check for any recent updates to the datasheet regarding pin configuration or recommended soldering profiles. Ensure compatibility with automated pick-and-place equipment given the small form factor.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency is required in a compact surface-mount footprint. Consider the ±10 ppm stability requirement against the application's timing accuracy needs. Evaluate the 80 Ohm ESR value for oscillator circuit compatibility. Verify that the -20°C to +70°C operating range meets the environmental conditions of the final product deployment.

Crystals Part Context

This crystal belongs to the 402 series from CTS-Frequency Controls, designed for general-purpose applications requiring reliable frequency control. The series offers various frequencies in a standardized small outline package. The 402F20011CAR specifically targets cost-sensitive designs needing stable timing without the complexity of active oscillators.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 10 pF load capacitance and 4-SMD no-lead packages. Verify that alternative parts maintain the same 80 Ohm ESR and ±10 ppm stability. Ensure replacement components support the same operating temperature range and mounting requirements.
