Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions align with moisture sensitivity level specifications to maintain performance integrity upon installation.

Selection Notes

Select this component when a 49.152 MHz reference is required with ±30 ppm stability. Consider the 18 pF load capacitance compatibility with oscillator circuit designs. Evaluate the -20°C to +70°C operating range against environmental constraints. Compare physical footprint requirements against available board space for the 5.0x3.2 mm package.

Part Context

This part belongs to QST's series of surface-mount quartz crystals. It shares dimensional characteristics with other models in the 5.0x3.2 mm form factor family. Different frequencies within this series utilize similar packaging technologies but vary in electrical parameters such as load capacitance and ESR values depending on the specific resonant requirements.

Replacement Considerations

Direct substitutes must match the 49.152 MHz frequency, 18 pF load capacitance, and ±30 ppm stability. Verify pinout compatibility and mechanical dimensions for direct replacement. Cross-reference equivalent parts from other manufacturers offering identical electrical specifications and package outlines.
