Oscillators Procurement Notes

Verify the specific suffix code against official datasheets to confirm exact frequency tolerance and package dimensions. Ensure the 1.8V supply requirement aligns with target circuit design. Confirm lead-free status and RoHS compliance through manufacturer documentation prior to integration into production lines.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V supply is required alongside standard LVCMOS signaling. Consider the ±50ppm stability specification against system jitter requirements. Evaluate the 4-SMD footprint constraints against available PCB real estate and thermal dissipation needs for the specific application environment.

Oscillators Part Context

This part belongs to the Mercury Electronic 18QHTF series of standard crystal oscillators. The series offers various frequencies and voltage options within a consistent small form factor. It serves as a direct replacement for other industry-standard XO components requiring similar electrical characteristics and physical dimensions.

Oscillators Replacement Considerations

Cross-reference pinout configurations and voltage levels with potential substitutes. Verify that alternative parts support the same LVCMOS output type and enable/disable functionality. Ensure thermal performance matches the -40°C to 85°C operational range specified for the original component.
