Crystals Procurement Notes

Verify the specific suffix ILR against the manufacturer's current datasheet to confirm package and tape/reel specifications. Confirm availability status as components may be subject to discontinuation or supply chain constraints. Ensure the ordering part number matches the required load capacitance and ESR values for the target circuit design.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency with 12 pF load capacitance is required. Verify that the circuit oscillator can drive the specified 100 Ohm ESR. Consider the 4-SMD size if board space is limited compared to larger 402 series packages. Check compatibility with the host device's input capacitance requirements.

Crystals Part Context

This part belongs to the CTS 402 series of general-purpose crystals. It shares the same physical footprint and electrical characteristics as other variants in the series but is tuned specifically for 27 MHz. It is designed for surface mount assembly processes and offers a balance of performance and size for standard digital applications.

Crystals Replacement Considerations

Direct substitutes include 402F27022IAR and 402F27022IKR from CTS-Frequency Controls. These parts share identical electrical parameters and mechanical dimensions. Verify that any alternative suffix meets the same RoHS3 and MSL level 1 requirements.
