Crystals Procurement Notes

Verify current availability status as distribution channels may list this part as discontinued or out of stock. Confirm that the specific suffix matches the required frequency code and packaging format. Ensure compatibility with existing PCB footprints and reflow soldering profiles defined for the 4-SMD package type before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a 20 MHz fundamental crystal with ±30 ppm stability is required for space-constrained designs. The 18 pF load capacitance must match the oscillator circuit requirements. Consider the 100 Ohm ESR limit for drive level sensitivity. Verify that the -20°C to +70°C operating range meets the environmental conditions of the target application.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series offers various frequencies and packages optimized for high-volume manufacturing. The 402F20033CDT specifically utilizes the standard 2.00mm x 1.60mm case size common in modern consumer electronics and industrial control boards requiring reliable timing references.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals with identical 18 pF load capacitance and similar physical dimensions. Verify that alternative parts maintain the same ±30 ppm stability and 100 Ohm ESR specifications to ensure circuit compatibility without redesign.
