Crystals Procurement Notes

Verify the specific suffix 'IDT' indicates tape and reel packaging when sourcing. Confirm that the 18pF load capacitance matches the target circuit design requirements. Check current availability status as distribution channels may vary. Ensure the 4-SMD footprint dimensions align with the printed circuit board layout constraints prior to procurement.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency is required with tight initial tolerance. The 18pF load capacitance must match the oscillator circuit's external capacitors. Consider the 60 Ohm ESR for drive level sensitivity. The wide temperature range suits industrial or automotive environments where standard commercial grades are insufficient.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series provides various frequencies and package sizes for general timing needs. The 402F54012IDT specifically addresses the need for a 54 MHz reference in space-constrained designs requiring high reliability and standard SMD mounting compatibility.

Crystals Replacement Considerations

Public confirmed substitute part numbers include 402F54012IDR. Verify that alternative packages or suffixes maintain identical electrical parameters such as frequency, load capacitance, and ESR before substitution.
