Crystals Procurement Notes

Verify the specific suffix configuration against official CTS documentation to ensure correct load capacitance and tolerance specifications. Confirm availability status as distribution channels may list discontinued or backordered items. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and sourcing integrity before procurement.

Crystals Selection Notes

Select this component when a 54 MHz fundamental frequency is required with tight ±10 ppm tolerance. Ensure the target circuit design accommodates a 10 pF load capacitance to maintain frequency accuracy. Verify that the operating environment remains within the specified -20°C to +70°C range. Consider the 4-SMD package size constraints during PCB layout planning to ensure adequate spacing and soldering reliability.

Crystals Part Context

This crystal belongs to the CTS 402 Series, which provides general-purpose surface-mount resonators. The series is characterized by consistent performance across various frequencies and package sizes. The 402F5401XIAT specifically targets applications needing high stability in a minimal footprint, distinguishing it from larger through-hole or older SMD variants in the manufacturer's portfolio.

Crystals Replacement Considerations

Direct substitutes must match the 54 MHz frequency, 10 pF load capacitance, and 4-SMD 2x1.6mm package. Verify ESR compatibility and temperature range alignment. Check for equivalent frequency tolerance and stability ratings. Ensure any replacement maintains RoHS3 compliance and fundamental mode operation to guarantee circuit functionality.
