Procurement Notes

Verify the specific load capacitance and equivalent series resistance values against the target circuit design requirements. Confirm that the operating temperature range meets the environmental specifications of the end application. Ensure compatibility with reflow soldering profiles recommended for lead-free assembly processes to maintain component integrity.

Selection Notes

Select this component when a precise 32.000 MHz timing reference is required in a small form factor. Consider the drive level sensitivity and load capacitance matching to ensure accurate frequency output. Evaluate the phase noise characteristics if the application involves sensitive RF or data conversion circuits requiring low jitter performance.

Part Context

This part belongs to QST's line of precision crystal oscillators, focusing on fundamental mode operation for cost-effective and stable frequency generation. The 1612 package size represents a balance between electrical performance and board space efficiency, commonly used in mobile and embedded systems where larger packages are impractical.

Replacement Considerations

Direct substitutes must match the 32.000 MHz frequency, 1612 package dimensions, and fundamental mode operation. Verify equivalent electrical parameters including load capacitance and stability tolerance. Cross-reference with other manufacturers offering similar SMD crystals ensuring identical pinout and mounting specifications.
