Procurement Notes
This product is officially marked as obsolete and not recommended for new design. Verify availability status carefully before procurement attempts. Contact the manufacturer or authorized distributors for potential stock inquiries or replacement guidance. Ensure compliance with RoHS 3 standards if applicable to legacy inventory usage.
Selection Notes
Select this component only for maintenance or retrofit projects requiring a direct replacement for older designs using REF1004 or similar references. Evaluate the 1.22V output level against system requirements. Consider the E-Line package constraints for PCB layout. Review the electrical characteristics for noise and impedance needs.
Part Context
The ZXRE1004 series includes SOT23 surface mount variants and E-Line through-hole equivalents. This specific model represents the E-Line version with 2% tolerance. The series is designed to replace industry-standard references while offering improved performance in low-current portable applications.
Replacement Considerations
The datasheet explicitly recommends using the ZXRE125 as a replacement for new designs. No other substitute part numbers are confirmed in the provided documentation.
