Procurement Notes

Verify the specific suffix designation against official IQD documentation to confirm exact tolerance and packaging specifications. Ensure compatibility with surface mount reflow processes. Confirm that the 18 pF load capacitance aligns with the target circuit design requirements before procurement.

Selection Notes

Select this component when a surface mount quartz crystal is required for 8 MHz applications. The HC49/4HSMX form factor offers a balance between size and performance. Consider the ±30 ppm tolerance and 40 Ohm ESR characteristics relative to the oscillator circuit's drive level and load requirements.

Part Context

This part belongs to the HC49/4HSMX series, representing a standard surface mount variant of the traditional HC-49/U through-hole crystal. IQD Frequency Products provides this series to bridge the gap between legacy through-hole designs and modern surface mount manufacturing needs, maintaining familiar electrical characteristics in a compact footprint.

Replacement Considerations

Cross-reference with other 8 MHz SMD crystals having similar load capacitance and ESR values. Verify mechanical dimensions and pinout compatibility if substituting with components from different manufacturers.
