Crystals Procurement Notes

Verify the specific suffix XIAT against official datasheets to confirm pin configuration and tape/reel specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Cross-reference the manufacturer's latest documentation for any packaging quantity changes or environmental compliance updates prior to ordering.

Crystals Selection Notes

Select this component when a fundamental mode crystal with high frequency accuracy is required in a compact surface-mount form factor. Consider the 60 Ohm ESR and 8pF load capacitance requirements for oscillator circuit design. Verify that the -40°C to +85°C temperature range meets the operational environment constraints of the target application.

Crystals Part Context

This part belongs to the 402F series of surface-mount crystals from CTS-Frequency Controls. The series is characterized by small footprint options suitable for high-density PCB layouts. It complements other frequency control products like the ATS and CA25 series, offering distinct advantages in size and mounting technology compared to through-hole alternatives.

Crystals Replacement Considerations

Direct substitutes include 402F4001XIKR and 402F4001XIDR from CTS-Frequency Controls. These variants share similar electrical characteristics but may differ in packaging suffixes or minor mechanical tolerances. Verify pin-out compatibility before substitution.
