PDZ9.1BF Equivalent & Substitute Parts

Part Overview

The PDZ9.1BF is a Zener diode manufactured by Nexperia USA Inc., classified as a surface mount component in the SOD-323 package. This device is rated for 9.23 V nominal Zener voltage with 400 mW maximum power dissipation and ±2% tolerance. The component is actively produced and maintains full compliance with RoHS3 and REACH regulations. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ9.1BF are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution logic is based on the following key parameters:

• Zener Voltage (Vz): 9.23 V nominal
• Tolerance: ±2%
• Maximum Power Dissipation: 400 mW
• Package Type: SOD-323 (SC-76)
• Mounting Configuration: Surface Mount
• Impedance (Zzt): 60 Ohms maximum
• Reverse Leakage Current: 500 nA @ 6 V
• Forward Voltage: 900 mV @ 10 mA maximum
• Operating Temperature Range: 150°C junction temperature
• Regulatory Compliance: RoHS3 Compliant, REACH Unaffected

Parts meeting all these specifications are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ9.1BF and PDZ9.1BZ are active products manufactured by Nexperia USA Inc. with identical electrical specifications and package configurations. Selection between these parts is based on availability and supply chain requirements rather than technical differentiation.

Both parts maintain full RoHS3 compliance and REACH unaffected status, meeting regulatory requirements for commercial and industrial applications. The Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates no moisture-related handling restrictions for either component.

The PDZ9.1BZ currently maintains higher inventory availability (30,952 pieces) compared to the PDZ9.1BF (10,921 pieces), which may influence procurement decisions based on lead time and stock requirements.

Frequently Asked Questions (FAQ)

Q: Can PDZ9.1BZ be used as a direct replacement for PDZ9.1BF?

A: Yes. Both parts are parametric equivalents with identical Zener voltage (9.23 V), tolerance (±2%), power rating (400 mW), impedance (60 Ohms), package type (SOD-323), and all electrical characteristics. No circuit modifications are required.
