Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing this component, as availability may vary between cut tape and reel formats. Confirm that the manufacturer designation matches IQD Frequency Products to ensure authenticity. Check current product status indicators, as some listings may indicate end-of-life or discontinuation statuses which could impact long-term supply chain stability.

Selection Notes

Select this component when a 32.768 kHz reference signal is required for time-based applications. Ensure the circuit design accommodates the 12.5 pF load capacitance to maintain accuracy. Verify that the PCB layout supports the 8.7 mm x 3.8 mm footprint and that the drive level requirements align with the 1 uW specification to prevent overdriving the crystal element.

Part Context

This part belongs to the 85SMX series of quartz crystals from IQD Frequency Products. It serves as a standard timing solution for applications needing accurate second-level counting. The tuning fork architecture provides high Q-factor characteristics essential for stable low-frequency operation in compact electronic devices.

Replacement Considerations

Direct substitutes include other 32.768 kHz SMD crystals with matching 12.5 pF load capacitance and similar physical dimensions. Verify ESR and drive level compatibility before substitution. Cross-reference with IQD's current active portfolio for updated equivalents if this specific variant is discontinued.
