Crystals Procurement Notes

Verify the specific suffix 'CDR' against official CTS documentation to confirm tape-and-reel packaging status. Ensure the selected variant matches the required 100 Ohm ESR specification for circuit compatibility. Cross-reference the manufacturer part number with authorized distributors to confirm current availability and authenticity before procurement.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental frequency is required with ±30 ppm stability. The 18pF load capacitance must match the oscillator circuit design. Consider the 4-SMD footprint constraints and the -20°C to 70°C operating temperature range relative to the application environment requirements.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers frequencies from 16MHz to 60MHz. The series typically provides standard frequency tolerances and utilizes surface-mount technology for automated assembly. The 402F20433CDR represents a specific frequency code within this broader family of crystals.

Crystals Replacement Considerations

Direct parameter-equivalent substitutes include the 402F20433CDT variant from CTS-Frequency Controls. Verify that any replacement maintains the identical 20.48 MHz frequency, 18pF load capacitance, and 100 Ohm ESR specifications.
