Crystals Procurement Notes

Verify the specific suffix CAT against the manufacturer's latest datasheet to confirm pinout and termination specifications. Ensure the selected variant matches the required load capacitance and ESR values for the target oscillator circuit. Confirm availability status as supply conditions may vary by distributor.

Crystals Selection Notes

Select this component when a low-frequency, high-stability reference is required for surface-mount designs. The 1.435 MHz frequency is suitable for baud rate generation or division in communication interfaces. Evaluate the ±25 ppm tolerance against system timing requirements and ensure the 10 pF load capacitance aligns with the host oscillator circuit design.

Crystals Part Context

This part belongs to the CTS 435 series of surface-mount crystals. The series offers various frequencies and packages optimized for consumer electronics and industrial applications. The 435F143Y5CAT specifically addresses needs for precise timing in compact form factors, providing reliability in standard commercial temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other 1.435 MHz crystals from CTS with identical 5.0x3.2mm footprints and electrical parameters. Verify that alternative parts maintain the same 10 pF load capacitance and ±25 ppm tolerance to ensure circuit compatibility without redesign.
