Crystals Procurement Notes

Verify the specific suffix 'CDR' against the manufacturer's current datasheet to confirm availability status, as some variants in this series may be discontinued or subject to long lead times. Ensure the required load capacitance matches the circuit design specifications before ordering.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency with ±10 ppm stability is required in a small 2.0x1.6 mm footprint. Consider the 60 Ohm ESR and 18 pF load capacitance requirements for oscillator circuit compatibility. Verify thermal performance within the specified -20°C to +70°C range for the target application environment.

Crystals Part Context

This part belongs to the CTS 402 Series of miniature crystals, designed for space-constrained electronic applications. The series offers various frequencies and packages, providing a standardized solution for timing needs in consumer electronics and industrial control systems requiring reliable surface-mount components.

Crystals Replacement Considerations

The 416F40011CDR is listed as a parameter-equivalent alternative by distributors, though it operates at 40 MHz rather than 50 MHz. Direct functional substitution requires verifying frequency compatibility. Check for updated series replacements from CTS if the 402F50011CDR is discontinued.
