Crystals Procurement Notes

Verify the specific suffix 'LR' against the manufacturer's current datasheet to confirm packaging and availability status, as distribution channels may list obsolete or discontinued variants. Ensure the load capacitance matches the target oscillator circuit design requirements before procurement.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with 12pF load capacitance is required. Confirm that the 60 Ohm ESR aligns with the oscillator circuit's drive level limitations. Verify that the 4-SMD footprint fits the PCB layout constraints.

Crystals Part Context

This part belongs to the CTS 402 Series of surface mount crystals. The series offers various frequencies and load capacitances in a standardized small outline package. The 402F54012ILR specifically addresses applications requiring 54 MHz timing with moderate stability.

Crystals Replacement Considerations

Direct substitutes within the same series include parts with identical electrical specifications but different packaging suffixes, such as 402F54012IDR. Cross-manufacturer replacements require matching frequency, load capacitance, ESR, and physical dimensions.
