Crystals Procurement Notes

Verify the specific suffix 'KT' against the manufacturer's official datasheet to confirm packaging configuration and availability status. Ensure that the load capacitance requirement of the target circuit matches the 8pF specification to maintain accurate frequency performance. Cross-reference the ESR value with oscillator driver strength requirements to prevent overdriving the crystal element.

Crystals Selection Notes

Select this component when a 20 MHz fundamental resonance is required with tight ±15 ppm stability constraints. The 4-SMD form factor is appropriate for space-constrained PCB layouts. Verify that the application environment remains within the -20°C to +70°C operational range to ensure specified frequency stability is maintained throughout the device lifecycle.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls. The series provides various frequency options and package sizes for general-purpose timing needs. The 402F2001XIKT specifically addresses the 20 MHz segment with standard commercial temperature ratings and fundamental mode operation.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 8pF load capacitance, 100 Ohm ESR, and 4-SMD (2x1.6mm) footprint. Verify that alternative components support the same ±15 ppm tolerance and fundamental operating mode to ensure circuit compatibility.
