Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Ensure the operating temperature range meets the environmental conditions of the final application. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure component integrity during assembly.

Oscillators Selection Notes

Select this component when a low-profile surface-mount oscillator is required for space-constrained designs. Consider the HCMOS output compatibility with downstream logic circuits. Evaluate the ±50 ppm stability against jitter sensitivity requirements. Compare the 1.8V to 3.3V supply range with available power rails in the target system architecture.

Oscillators Part Context

This part belongs to the S3 series of ultra-miniature crystal oscillators from Aker Technology. The series is characterized by small form factors suitable for portable devices. The S31805T variant specifically denotes a standard package size within this family. These components are designed to replace larger through-hole or standard surface-mount oscillators in modern miniaturized electronics.

Oscillators Replacement Considerations

Direct substitutes include other S31805T variants with different frequencies, such as S31805T-32.000-X-R or S31805T-19.200-X-R, provided the frequency difference is acceptable. Cross-reference with similar 4-SMD HCMOS oscillators from other manufacturers if supply chain issues arise, ensuring pinout and electrical specifications match.
