Crystals Procurement Notes

Verify the specific suffix 'A' indicates the 10pF load capacitance variant, as other suffixes denote different values. Confirm current availability status, as this part may be discontinued or subject to long lead times. Ensure the application circuit matches the 10pF load requirement to maintain frequency accuracy within the specified ±20 ppm tolerance.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with 10pF load capacitance is required in a sub-miniature SMD package. Compare against the 402F54022ILT (12pF) or 402F54022IKT (8pF) if load capacitance requirements differ. Consider the 402F54022IAR only if the hermetic ceramic package and specific dimensional constraints align with the PCB layout and thermal management needs.

Crystals Part Context

This part belongs to the CTS 402 Series, a line of sub-miniature surface-mount crystals. The series covers frequencies from 16 MHz to 96 MHz and utilizes a consistent 2.0mm x 1.6mm footprint. The 402F54022IAR specifically targets applications needing precise timing in compact designs, sharing mechanical dimensions with other variants in the family while differing in electrical parameters like load capacitance.

Crystals Replacement Considerations

Direct substitutes include 402F54022ILR and 402F54022IJR, which share identical electrical specifications but may differ in packaging or supply chain status. Verify that any replacement maintains the 10pF load capacitance and 60 Ohm ESR to ensure circuit compatibility.
