Procurement Notes

Verify the specific packaging suffix against the manufacturer's current datasheet to confirm physical dimensions and terminal configuration. Ensure the selected variant matches the required load capacitance and operating temperature range for the target application environment. Cross-reference the RoHS compliance status with local regulatory requirements before finalizing procurement orders.

Selection Notes

Select this component when a surface-mount quartz crystal with 8 MHz nominal frequency and 16 pF load capacitance is required. Consider the ±30 ppm tolerance and 40 Ω ESR specifications for circuit compatibility. Evaluate the HC-49/4HSMX package size constraints against the PCB layout requirements to ensure proper placement and soldering reliability during manufacturing.

Part Context

This part belongs to the IQD Frequency Products quartz crystal family, which includes various fundamental and overtone resonators. The LFXTAL series typically offers industry-standard packages suitable for high-volume production. IQD provides these components for applications demanding reliable frequency stability across defined temperature ranges.

Replacement Considerations

Direct substitutes must match the 8 MHz frequency, 16 pF load capacitance, HC-49/4HSMX package, and ±30 ppm tolerance. Verify equivalent ESR and drive level specifications to maintain circuit oscillation stability. Consult official cross-reference lists for confirmed compatible alternatives from IQD or other manufacturers.
