Crystals Procurement Notes

Verify current availability status as the part may be discontinued or subject to limited supply. Confirm that the specific ordering suffix matches the required load capacitance and frequency tolerance. Ensure compatibility with existing PCB footprint dimensions and reflow soldering profiles. Check for alternative lead-free packaging requirements if applicable to your manufacturing process. Validate that the moisture sensitivity level aligns with your storage and handling capabilities.

Crystals Selection Notes

Select this component when a 37.4 MHz fundamental frequency is required for system synchronization. The 18 pF load capacitance must match the oscillator circuit design to achieve specified accuracy. Consider the ±15 ppm stability requirement against system timing budgets. Evaluate the 4-SMD package size constraints within the overall mechanical layout. Assess thermal performance within the -20°C to 70°C operational range for the intended environment.

Crystals Part Context

This crystal belongs to the CTS 402 series, which provides general-purpose frequency control solutions. The series offers various frequencies and package options for embedded applications. As a legacy product line, these components are mature but may not be recommended for new designs. Engineers should verify long-term supply chain stability before integration into production hardware.

Crystals Replacement Considerations

Consult official CTS documentation for direct cross-references. Verify identical electrical parameters including frequency, load capacitance, and ESR. Ensure physical footprint compatibility for seamless replacement. Check manufacturer recommendations for updated series alternatives if the 402 series is phased out.
