Crystals Procurement Notes

Verify the specific suffix CD against the manufacturer datasheet to confirm pinout and electrical characteristics match system requirements. Ensure compatibility with reflow soldering profiles defined in the thermal data sheet. Confirm availability status as supply conditions may vary by distributor. Check for alternative packages if footprint constraints differ from the standard 4-SMD form factor.

Crystals Selection Notes

Select this component when a 50 MHz fundamental frequency is required with ±15 ppm stability. The 18 pF load capacitance must match the oscillator circuit design. Consider the 60 Ohm ESR for drive level limitations. The 4-SMD package suits space-constrained PCB layouts. Verify temperature range suitability for the intended operational environment.

Crystals Part Context

This part belongs to the 402 Series of MHz crystals from CTS-Frequency Controls. The series provides various frequency options in standardized SMD packages. The 402F500XXCDT specifically addresses the 50 MHz requirement with defined electrical parameters. It is distinct from other suffixes like CKT or CAR which may have different load capacitances or packaging configurations.

Crystals Replacement Considerations

Direct substitutes include the 402F500XXCAR and 402F500XXCLR from the same manufacturer. These parts share similar electrical characteristics but may differ in load capacitance or package details. Verify pin compatibility and parameter alignment before substitution.
