Substitute Part Grouping Explanation

Substitution of the obsolete BAT721C/ZLR is based on the following critical parameters:

Package Compatibility: Both the main part and substitute maintain TO-236AB (SC-59, SOT-23-3) surface mount packaging, ensuring mechanical and electrical interface compatibility with existing PCB layouts.

Technology Type: The substitute part utilizes Schottky diode technology, matching the original component's rectification characteristics and forward voltage behavior.

Compliance Requirements: The substitute part maintains RoHS3 compliance and REACH unaffected status, preserving regulatory alignment with the original specification.

Electrical Performance: The substitute part operates within the electrical parameters required for Schottky diode applications, with defined voltage and current ratings suitable for small signal rectification.

The active substitute BAT721C,215 from Nexperia USA Inc. fulfills these substitution criteria and is currently in production with established supply availability.
