Procurement Notes

Verify the specific suffix 'MAGE' against official QST documentation to confirm the exact frequency tolerance and temperature range specifications. Ensure the selected variant matches the required load capacitance and package dimensions for the target PCB layout. Cross-reference part numbers carefully as suffixes often denote critical electrical differences.

Selection Notes

Select this component when a 12 MHz fundamental frequency is required in a compact 3.2x2.5mm footprint. Consider the ±50ppm stability rating relative to system clock accuracy requirements. Verify that the 12pF load capacitance aligns with the oscillator circuit design parameters before finalizing the selection.

Part Context

This part belongs to the QT325G series of MHz crystals from QST. The series offers various stability options denoted by suffix letters, with 'G' indicating ±50ppm stability over the extended industrial temperature range. These components are standard passive elements used for precise timing in electronic circuits.

Replacement Considerations

Public confirmed substitute part numbers include QT325G-12.000MAHJ-T and QT325G-12.000MDHK-T. Verify parameter equivalence for these alternatives.
