Crystals Procurement Notes

Verify the specific suffix 'JR' against official CTS documentation to confirm package and tape/reel specifications. Ensure compatibility with existing circuit load capacitance requirements before integration. Cross-reference datasheet parameters for ESR and stability limits to validate performance in the target application environment.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency with ±10ppm tolerance is required. The 9pF load capacitance must match the oscillator circuit design. Consider the 4-SMD footprint and 0.55mm height for mechanical clearance constraints. Verify that the 60 Ohm ESR aligns with the driving circuit's oscillation conditions.

Crystals Part Context

This part belongs to the CTS 402 Series of surface-mount crystals. It shares the standard 2.00mm x 1.60mm footprint common to this family. The 'I' suffix typically denotes specific packaging or terminal finish variations within the manufacturer's lineup, requiring datasheet verification for exact physical attributes.

Crystals Replacement Considerations

Direct substitutes include 402F5401XILR and 402F5401XIKR from CTS-Frequency Controls. These parts share identical electrical characteristics but may differ in packaging or reel specifications. Verify pinout and mechanical dimensions before substitution.
