Crystals Procurement Notes

Verify the specific suffix ID against the manufacturer datasheet to confirm exact tolerance and packaging specifications. Ensure compatibility with the target circuit's load capacitance requirements. Check current availability status as component stock levels fluctuate. Confirm RoHS compliance and environmental ratings match project constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with ±10 ppm stability is required. The 18 pF load capacitance must align with the host oscillator circuit design. Consider the 4-SMD package size for space-constrained PCB layouts. Evaluate thermal performance within the specified operating temperature range for the intended application environment.

Crystals Part Context

This part belongs to the 402 series of surface-mount crystals from CTS-Frequency Controls. The series provides various frequency options and tolerance grades in standardized packages. The 402F2001XIDR specifically targets applications needing moderate stability in a small footprint, distinguishing it from higher-stability or through-hole variants.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 18 pF load capacitance and ±10 ppm tolerance. Verify pinout compatibility and physical dimensions to ensure mechanical fit. Cross-reference ESR values to maintain circuit stability. Consult manufacturer cross-reference lists for validated alternative part numbers.
