Crystals Procurement Notes

Verify the specific suffix 'XIAT' against official CTS datasheets to confirm exact load capacitance and tolerance specifications, as suffixes often denote critical electrical variations. Ensure compatibility with reflow soldering profiles defined in the manufacturer's mounting guidelines. Cross-reference RoHS compliance status if required by assembly standards. Confirm availability through authorized distributors to avoid counterfeit components.

Crystals Selection Notes

Select this component when a 27 MHz fundamental frequency is required with a 10 pF load capacitance. Consider the 100 Ohm ESR value for oscillator circuit stability. The 4-SMD footprint suits high-density PCB layouts. Evaluate the ±10 ppm tolerance against system timing requirements. Ensure the -40°C to +85°C range meets environmental conditions.

Crystals Part Context

Part of the 402 Series from CTS-Frequency Controls, designed for general-purpose timing applications. The series utilizes standard AT-cut quartz resonators. Similar variants exist with different load capacitances or tolerances, distinguished by alphanumeric suffixes. This model represents a standard commercial-grade option within the broader portfolio.

Crystals Replacement Considerations

Direct substitutes include 402F2701XIJR and 402F2701XIAR from CTS-Frequency Controls, though load capacitance may differ. Verify pinout and dimensional compatibility before substitution. Other manufacturers offering 27 MHz 4-SMD crystals require matching ESR and load capacitance parameters.
