Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to ensure correct voltage, frequency tolerance, and packaging specifications. Confirm that the selected variant matches the required supply voltage and frequency stability for the target application. Cross-reference the part number with the latest datasheet revision to avoid discrepancies in pinout or electrical characteristics. Ensure compliance with RoHS standards if required by the project specifications.

Selection Notes

Select this component when space constraints require a compact 2016 footprint combined with strict EMI requirements. The 3.3V supply option suits standard logic levels, while the wide temperature range ensures reliability in harsh environments. Consider the enable pin functionality if dynamic power management or emission control is necessary during system operation.

Part Context

This model belongs to the QTM216E series of low EMI oscillators from QST. The series is characterized by its ability to reduce spectral peaks through phase modulation, eliminating the need for additional ferrite beads or capacitors typically used in standard crystal oscillator designs. The ceramic package offers superior thermal and mechanical stability compared to plastic packages.

Replacement Considerations

Direct substitutes include other QTM216E variants with different frequencies or voltages, such as QTM216E-24.000MBM-T or QTM216E-20.000MBM-T, provided the electrical parameters match the design requirements. Verify pin compatibility and package dimensions before substitution.
