Crystals Procurement Notes

Verify the specific suffix 'JR' against official manufacturer documentation to confirm packaging and tape-and-reel specifications. Ensure compatibility with existing circuit load capacitance requirements before procurement. Cross-reference datasheet revisions to confirm current production status and compliance certifications.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency crystal is required with a 9 pF load capacitance. Consider the ±10 ppm tolerance and ±20 ppm stability limits relative to system timing accuracy needs. Verify that the 4-SMD footprint matches the target PCB design and thermal management strategy.

Crystals Part Context

This part belongs to the CTS 402 series of surface-mount crystals. It shares the same physical footprint and general electrical characteristics as variants like the 402F54012IDR and 402F54022IJT, differing primarily in load capacitance and suffix-specific packaging attributes defined by the manufacturer.

Crystals Replacement Considerations

The 402F54012IDR is listed as a parameter-equivalent alternative within the same product family. Verify that the replacement variant maintains identical load capacitance and frequency stability requirements for direct substitution.
