Crystals Procurement Notes

Verify the specific operating temperature range against application requirements, as datasheet data indicates a minimum of -20°C rather than the standard -10°C found in other series variants. Confirm that the 40 Ohm ESR aligns with the oscillator circuit design. Ensure the HC-49/US footprint matches the PCB layout constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a standard surface mount crystal footprint is required for 16 MHz applications. The HC-49/US form factor offers a balance between mechanical robustness and space efficiency compared to smaller SMD packages. Consider the ±30 ppm tolerance if high precision is not critical, and verify that the 18 pF load capacitance matches the host circuit's input capacitance specifications.

Crystals Part Context

This part belongs to the CSM1 series of low-profile surface mount crystals from Cardinal Components. The series provides cost-effective alternatives to through-hole components while maintaining reliable performance. The CSM1 series utilizes AT-cut crystals for superior frequency stability over temperature variations, serving as a foundational passive component in various electronic assemblies.

Crystals Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing designs using generic equivalents that match the 16 MHz frequency, 18 pF load capacitance, and HC-49/US package dimensions.
