Crystals Procurement Notes

Verify the specific suffix 'CDT' against the manufacturer's official datasheet to confirm the 18pF load capacitation specification, as suffix variations may indicate different electrical parameters or packaging options. Ensure the selected variant matches the target circuit design requirements for load capacitance and physical footprint compatibility before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 30 MHz fundamental frequency crystal with 18pF load capacitance is required for space-constrained designs. The 4-SMD no-lead package suits automated surface mount assembly processes. Consider the ±15 ppm stability and -20°C to +70°C operating range to ensure compatibility with the environmental conditions and timing accuracy needs of the intended electronic application.

Crystals Part Context

This part belongs to the 402 Series of miniature SMD crystals from CTS-Frequency Controls. The series provides various frequency and load capacitance options in standardized small footprints. The 402F300XXCDT specifically addresses applications requiring a 30 MHz output with 18pF loading, distinguishing it from other variants like the 402F300XXCJR which utilizes a 9pF load capacitance.

Crystals Replacement Considerations

The 402F300XXCDR is listed as a direct substitute by the manufacturer. Verify that the alternative maintains identical 18pF load capacitance, 80 Ohm ESR, and 4-SMD(2x1.6) package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
