Crystals Procurement Notes

Verify the specific suffix requirements against the manufacturer's current datasheet, as ordering codes may dictate packaging or testing variations. Confirm availability status directly with authorized distributors, as supply chain fluctuations may affect immediate stock levels. Ensure that the selected variant matches the required load capacitance and ESR specifications for the target circuit design.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required with strict ±20ppm stability. The 60 Ohm ESR limit must align with the oscillator circuit's drive level capabilities. Consider the 12pF load capacitance requirement to ensure proper frequency matching with the host device's internal capacitors.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers frequencies from 16MHz to 60MHz. The series is characterized by small form factors suitable for space-constrained electronics. The 402F37422ILR specifically addresses the need for reliable timing in digital logic applications requiring high accuracy within a standard SMD package.

Crystals Replacement Considerations

Direct substitutes include 402F37422ILT and 402F37422IAR from CTS-Frequency Controls. These variants share identical electrical parameters and physical dimensions, differing primarily in packaging configuration or manufacturing lot specifics. Verify pin compatibility and mounting orientation before substitution.
