Procurement Notes

Verify that the specific suffix matches the required load capacitance and ESR specifications for your circuit design. Confirm package dimensions align with PCB footprint requirements. Ensure environmental compliance meets project standards. Cross-reference manufacturer datasheets for detailed electrical characteristics before finalizing procurement decisions.

Selection Notes

Select this component when a 10 MHz fundamental frequency crystal is required in a small 3.2x2.5mm SMD package. Consider the 150 Ohm ESR and 18pF load capacitance requirements to ensure proper oscillator circuit tuning. Evaluate the ±30ppm stability against system timing accuracy needs within the specified -40°C to +85°C operating range.

Part Context

This part belongs to the QT325G series of quartz crystals from QST, characterized by their small form factor suitable for space-constrained designs. The series offers various frequencies with consistent packaging and performance metrics, providing designers with standardized components for reliable timing applications across consumer and industrial electronics.

Replacement Considerations

Direct substitutes must match the 10 MHz frequency, 18pF load capacitance, 150 Ohm ESR, and 3.2x2.5mm package dimensions. Verify that alternative parts support fundamental mode operation and meet the same ±30ppm stability and temperature range specifications.
