Crystals Procurement Notes

Verify the specific suffix code required for your application, as the 'XX' indicates variable parameters such as tolerance or packaging. Confirm that the 18pF load capacitance matches your circuit design requirements. Ensure compatibility with the -20°C to +70°C operating temperature range. Check for any specific handling instructions related to the surface-mount package type during assembly.

Crystals Selection Notes

Select this component when a 32 MHz fundamental frequency is required with ±15ppm stability. The 18pF load capacitance must align with the oscillator circuit's input capacitance. Consider the 4-SMD footprint for PCB space constraints. Verify ESR limits against oscillator drive level specifications to ensure reliable startup and operation within the industrial temperature range.

Crystals Part Context

This part belongs to the 402 Series from CTS-Frequency Controls, which offers various surface-mount crystals. The 402F320XXCDR specifically denotes the 32 MHz variant with 18pF load capacitance. It is distinct from other series like the 416, which may offer different footprints or electrical characteristics. The series provides options for different tolerances and packaging configurations.

Crystals Replacement Considerations

Direct substitutes include parts from the same family with matching electrical parameters, such as the 402F320XXCDT. Verify pinout compatibility and mechanical dimensions before substitution. Ensure the replacement maintains the required ±15ppm stability and 18pF load capacitance.
