Crystals Procurement Notes

Verify current availability status through authorized distributors, as supply conditions may vary. Confirm that the specific suffix 'CDT' matches the required 18pF load capacitance specification for your circuit design. Ensure compatibility with standard reflow soldering profiles suitable for 4-SMD packages. Cross-reference part numbers carefully to distinguish between different load capacitance variants within the 416 series.

Crystals Selection Notes

Select this component when an 18pF load capacitance is required for the target oscillator circuit. Compare against other 416 series variants such as CAR or CAT if different capacitance values like 10pF are needed. Verify that the ±30ppm tolerance meets the system's frequency accuracy requirements. Consider the physical footprint of the 1.60mm x 1.20mm package for PCB layout constraints.

Crystals Part Context

This part belongs to the CTS 416 series of miniature surface-mount crystals. The series provides various load capacitance options including 10pF, 12pF, and 18pF configurations. The 416F40635CDT specifically denotes the 18pF variant. Other suffixes indicate different packaging or capacitance specifications within the same frequency family.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers include 416F40635ADR and 416F40635CDR. These alternatives share identical electrical parameters and package dimensions. Verify that any replacement maintains the 18pF load capacitance requirement.
