Procurement Notes

Verify the specific suffix 'CCZQ' against official datasheets to confirm package type and temperature grade. Confirm RoHS compliance status as historical records may vary. Check current lifecycle status as this part may be discontinued or subject to limited availability. Ensure sourcing from authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a low-cost, fixed 1.23V reference is required for through-hole designs. Consider the 50ppm/°C temperature coefficient for thermal stability needs. Evaluate the TO-92-2 package constraints for PCB layout. Compare against series variants like ICL8069CCSA if surface-mount options are preferred.

Part Context

The ICL8069CCZQ belongs to the ICL8069 family of low-voltage shunt references. This family includes various package options such as SOIC and TO-92. These devices are commonly used in analog signal conditioning and ADC reference applications where moderate precision and low cost are prioritized over ultra-high stability.

Replacement Considerations

Check for direct pin-compatible substitutes within the ICL8069 series, such as ICL8069CCSA for surface mount. Verify electrical parameters match before substitution. Consult manufacturer obsolescence notices for recommended new design-ins.
