PDZ10B-QZ Equivalent & Substitute Parts

Part Overview

The PDZ10B-QZ is a Zener diode manufactured by Nexperia USA Inc., designed for voltage regulation and protection applications in electronic circuits. This surface mount component operates at a nominal Zener voltage of 10 V with a maximum power dissipation of 400 mW. The part is currently in active production status and carries automotive-grade qualification under AEC-Q101 standards. Identifying equivalent substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required, or when sourcing from different inventory channels is needed while maintaining identical electrical and mechanical performance.

Substitute Part Grouping Explanation

Substitute parts for the PDZ10B-QZ are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Voltage - Zener (Nom): 10 V
• Tolerance: ±2%
• Power - Max: 400 mW
• Impedance (Max): 10 Ohms
• Current - Reverse Leakage @ Vr: 100 nA @ 7 V
• Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 100 mA
• Operating Temperature: 150°C (TJ)
• Package / Case: SC-76, SOD-323
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes. The PDZ10B,115 meets all specified electrical and mechanical requirements and is therefore a valid substitute for the PDZ10B-QZ.

Parameter Comparison

Engineering Selection Recommendations

The PDZ10B,115 is a direct parametric equivalent to the PDZ10B-QZ. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications, mechanical packaging, and compliance certifications. Both components maintain active production status and carry ROHS3 compliance and REACH unaffected designation. The PDZ10B,115 is suitable for direct substitution in applications where the PDZ10B-QZ is specified, provided that the circuit design does not impose additional constraints beyond the stated electrical and mechanical parameters.

Selection between these parts should be based on inventory availability, lead time requirements, and procurement channel preferences, as all technical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can PDZ10B,115 be used as a direct replacement for PDZ10B-QZ?

A: Yes. The PDZ10B,115 meets all electrical and mechanical specifications of the PDZ10B-QZ, including Zener voltage, power rating, impedance, leakage current, forward voltage, operating temperature range, package type, and compliance certifications. Direct substitution is supported.

Q: Are there any differences in the package or mounting between these parts?

A: No. Both parts use the SOD-323 package in SC-76 form factor and are configured for surface mount assembly. Printed circuit board layouts and reflow profiles remain unchanged.

Q: Do both parts meet automotive qualification requirements?

A: The PDZ10B-QZ carries explicit automotive grade designation with AEC-Q101 qualification. The PDZ10B,115 specifications indicate active product status and identical electrical performance. Confirmation of automotive qualification status for PDZ10B,115 should be obtained from the manufacturer datasheet if automotive application requirements are mandatory.

Q: What is the difference between PDZ10B-QZ and PDZ10B,115 part numbering?

A: Both part numbers reference the same base product (PDZ10) with identical electrical and mechanical specifications. The different suffixes (-QZ versus ,115) represent different packaging or distribution formats from Nexperia USA Inc. The electrical performance and functionality are equivalent.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity level is 1 (Unlimited) for both components.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are parametrically identical and carry the same compliance certifications, they can be used interchangeably within the same circuit design and production environment.
