Crystals Procurement Notes

Verify the specific suffix 'E' indicates the required industrial temperature range (-40°C to +85°C) and 20pF load capacitance. Confirm that the 4-SMD footprint matches the target PCB land pattern. Ensure the 60 Ohm ESR aligns with the oscillator circuit design requirements before finalizing procurement.

Crystals Selection Notes

Select this part when a 14.31818 MHz reference is needed with strict industrial temperature compliance. Compare against the 405I35E variant if extended temperature ranges are not required but similar electrical parameters are desired. Verify that the 20pF load capacitance matches the host circuit's stray capacitance calculations.

Crystals Part Context

This component belongs to the CTS 405 Series of SMD crystals. It shares the same physical footprint as other variants in the series but differs in frequency and temperature specifications. It serves as a direct replacement for legacy through-hole crystals where space reduction is necessary.

Crystals Replacement Considerations

The 405I35E14M31818 is a documented substitute from the same manufacturer, offering identical electrical characteristics but potentially different packaging or availability status.
