Procurement Notes

Verify the specific suffix 'MEIY' against official QST documentation to confirm exact tolerance and temperature range specifications. Ensure the ordering part number matches the required load capacitance and frequency stability parameters for your design. Cross-reference with authorized distributors to confirm current availability and authenticity of the components before finalizing procurement orders.

Selection Notes

Select this component when a 48 MHz reference is required in a minimal 1.60mm x 1.20mm package. Consider the ±10 ppm stability rating for applications demanding moderate precision within the commercial temperature range. Evaluate the 8 pF load capacitance compatibility with the target oscillator circuit to ensure proper frequency accuracy and startup characteristics.

Part Context

This part belongs to the QT161S series of ultra-miniature crystals from QST. The series is characterized by small physical dimensions and low profile heights, targeting modern electronics where board space is limited. It serves as a fundamental resonator element for generating stable clock signals in various digital systems.

Replacement Considerations

Direct substitutes must match the 48 MHz frequency, 4-SMD No Lead package, and identical dimensional constraints. Verify equivalent electrical parameters including load capacitance and stability ratings. Consult QST's official cross-reference guides for validated alternative part numbers within the same product family.
