Crystals Procurement Notes

Verify the complete part number including suffixes against official TXC documentation to ensure correct frequency, tolerance, and package specifications. Confirm RoHS compliance status and AEC-Q200 qualification if automotive applications are required. Check current availability as distribution status may vary by region. Ensure compatibility with existing circuit load capacitance requirements before procurement.

Crystals Selection Notes

Select this component when a 20 MHz reference is needed with moderate stability requirements. The 8 pF load capacitance must match the oscillator circuit design. Consider the limited temperature range compared to wider industrial variants. Evaluate footprint constraints against the 1.6x1.2 mm package size. Compare ESR values with other crystals to ensure proper oscillation startup conditions in the target application.

Crystals Part Context

This part belongs to the TXC 8Q series of miniature quartz crystals. The series offers various frequencies and packages optimized for consumer electronics and general-purpose digital applications. The 8Q designation indicates specific dimensional and performance characteristics distinct from other TXC crystal families like the AA or AV series.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz crystals with identical 1.6x1.2mm SMD footprints, 8pF load capacitance, and ±30ppm tolerance. Verify that alternative parts meet the same -20°C to +70°C operating temperature range and have comparable ESR values to maintain circuit stability.
