Crystals Procurement Notes

Verify the specific suffix CC38 against official Suntsu documentation to confirm the exact temperature range and tolerance specifications. Ensure that the 4-SMD package dimensions match the target PCB footprint. Confirm RoHS compliance status through the manufacturer's current datasheet rather than distributor summaries. Validate that the 15pF load capacitance aligns with the circuit design requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a stable 18.432 MHz reference is required for digital logic or communication interfaces. The ±25 ppm tolerance suits applications where moderate frequency accuracy is sufficient. Consider the -40°C to +85°C operating range for industrial or consumer electronics environments. The low ESR value helps minimize phase noise in sensitive oscillator circuits compared to higher resistance alternatives.

Crystals Part Context

This part belongs to the SXT32415 series of surface-mount crystals from Suntsu Electronics. The series offers various frequency options and tolerance grades tailored for different timing applications. The SXT32415CC38 variant specifically targets general-purpose timing needs with balanced performance characteristics. It complements other components in the same family that may offer tighter tolerances or different temperature ranges.

Crystals Replacement Considerations

Direct substitutes include other 18.432 MHz crystals with identical 15pF load capacitance and compatible ESR values. Verify that alternative parts support the same 4-SMD package outline to ensure mechanical compatibility. Check if replacement components meet the required ±25 ppm tolerance and -40°C to +85°C temperature range specifications.
