Substitute Part Grouping Explanation

Substitute parts for the PDZ4.7B/ZLF are identified based on the following substitution criteria:

Primary Substitution Logic:

• Base Product Number Match: All substitutes share the base product number PDZ4.7, indicating identical Zener voltage rating (4.7 V nominal)
• Package Compatibility: All substitutes utilize SOD-323 surface mount package, ensuring mechanical and footprint compatibility
• Regulatory Compliance: All substitutes maintain ROHS3 compliance and REACH unaffected status, meeting environmental and regulatory requirements
• Electrical Specifications: Substitutes maintain consistent Zener voltage (4.7 V), power rating (400 mW), and tolerance (±2%), ensuring functional equivalence in voltage regulation applications
• Mounting Type: All substitutes are surface mount devices, compatible with automated assembly processes

The PDZ4.7B,135 variant is classified as a direct manufacturer substitute, produced by Nexperia USA Inc. (successor entity to NXP semiconductor operations), with identical electrical performance and packaging specifications.
