Procurement Notes

Verify the specific suffix 'MDE' against the manufacturer's current datasheet to confirm voltage levels and enable functionality. Ensure the ordering part number matches the required tolerance and temperature range specifications. Confirm package dimensions align with the target footprint design before finalizing procurement orders.

Selection Notes

Select this component when a low-voltage CMOS oscillator with control capabilities is required. Compare alternative frequencies within the QTM532 series if different timing speeds are needed. Evaluate board space constraints against the 5.0x3.2mm package size. Consider thermal performance requirements relative to the specified -40°C to +85°C operational range.

Part Context

This model belongs to the QTM532 series of surface-mount oscillators from QST. The series provides various frequency options in a standardized small outline package. It serves as a direct replacement for legacy through-hole crystals where stable, buffered clock signals are necessary for modern digital circuits.

Replacement Considerations

Check for QTM532 variants with different frequency suffixes or voltage codes. Verify compatibility with QTM532 models offering different tolerance grades or temperature ranges.
