Crystals Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's current datasheet to confirm packaging configuration and availability status. Cross-reference the exact part number with official CTS documentation to ensure compliance with RoHS3 standards and moisture sensitivity level requirements before integration into production designs.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental crystal is required with tight ±10ppm tolerance. Ensure the application circuit can support the specified 8pF load capacitance and 60 Ohm ESR. Verify that the operating temperature range meets the environmental demands of the target system.

Crystals Part Context

This part belongs to the CTS 402 series of surface mount crystals. The series is characterized by reliability and low phase noise performance. The 402F3741XIKR specifically utilizes a 4-SMD footprint, distinguishing it from larger through-hole or different SMD variants within the broader product line.

Crystals Replacement Considerations

Direct substitutes must match the 37.4 MHz frequency, 8pF load capacitance, 60 Ohm ESR, and 4-SMD (2x1.6mm) package dimensions. Verify pin compatibility and electrical parameters with alternative manufacturers' offerings to ensure functional equivalence.
