Crystals Procurement Notes

Verify the specific suffix 'IJR' against the manufacturer's current datasheet to confirm package dimensions and pin configuration. Ensure the load capacitance requirement of the target circuit matches the component's 9 pF specification. Confirm availability status as supply conditions may vary. Cross-reference the ESR value of 80 Ohms with oscillator circuit design requirements to ensure proper startup and stability.

Crystals Selection Notes

Select this component when a precise 30.72 MHz timing source is required in a small form factor. The 9 pF load capacitance dictates specific PCB trace and circuit loading considerations compared to standard 12 pF or 20 pF crystals. The ±20 ppm tolerance is suitable for general digital logic applications but may require tighter specifications for high-speed serial communications. Verify that the 4-SMD footprint aligns with the assembly equipment capabilities.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers a frequency range typically between 16 MHz and 60 MHz. The series utilizes standard AT-cut quartz resonators optimized for surface mount technology. The 402 series is designed to replace through-hole components like HC-49 packages in modern automated assembly processes while maintaining comparable electrical performance characteristics.

Crystals Replacement Considerations

Direct substitutes include 402F30722IKT and 402F30733CJT from CTS-Frequency Controls. These alternatives share similar electrical parameters and package types. Verify that any replacement maintains the 9 pF load capacitance and 80 Ohm ESR values to ensure circuit compatibility.
