Crystals Procurement Notes

Verify the specific suffix 'DR' against the manufacturer's datasheet to confirm the 18pF load capacitation specification. Ensure that the ordering documentation explicitly matches the part number 402F2701XIDR to avoid confusion with similar variants such as XIJR or XIAR which may have different electrical characteristics. Confirm RoHS compliance status prior to final procurement.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with an 18pF load capacitance. The 100 Ohm ESR and ±10ppm tolerance suit applications demanding moderate precision. The 4-SMD footprint requires compatible PCB land patterns. Verify oscillator circuit design compatibility with the specified load capacitance and ESR values before integration.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. The series provides various frequency options and package sizes for general-purpose timing applications. The 402F2701XIDR specifically utilizes the standard 4-SMD no-lead form factor common in modern electronics manufacturing.

Crystals Replacement Considerations

The 402F2701XIJR is listed as a similar alternative by the manufacturer. However, verify if the load capacitance differs between these suffixes. Direct substitution requires confirmation that the 18pF specification remains consistent across both part numbers.
