PDZ16B-QZ Equivalent & Substitute Parts

Part Overview

The PDZ16B-QZ is a 16 V Zener diode manufactured by Nexperia USA Inc., designed for surface mount applications in the SOD-323 package. This component operates at a maximum power dissipation of 400 mW with ±2% voltage tolerance and is qualified to AEC-Q101 automotive standards. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging format requirements differ. All substitute parts maintain identical electrical specifications and mechanical compatibility within the SOD-323 package family.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ16B-QZ are identified based on strict electrical and mechanical parameter matching. All substitute parts maintain the following critical specifications:

Electrical Parameters (Must Match):

• Zener voltage: 16 V nominal
• Voltage tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 20 Ohms
• Reverse leakage current: 50 nA @ 12 V
• Forward voltage: 1.1 V maximum @ 100 mA
• Junction temperature rating: 150°C

Mechanical Parameters (Must Match):

• Package type: SOD-323 (SC-76)
• Mounting type: Surface Mount
• Supplier device package: SOD-323

Compliance Parameters (Must Match):

• Product status: Active
• RoHS status: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)
• REACH status: REACH Unaffected

The substitute parts differ only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical performance or mechanical compatibility in the end application.

Parameter Comparison

Engineering Selection Recommendations

All three part numbers—PDZ16B-QZ, PDZ16B,115, and PDZ16B,135—are electrically and mechanically equivalent for circuit design purposes. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

PDZ16B-QZ (Primary Part): Supplied in Tape & Reel format. Select this part number when standard reel packaging is required for automated assembly processes.

PDZ16B,115 (Substitute): Supplied in Cut Tape and Digi-Reel® format. Select this part number when smaller quantities or alternative reel formats are needed, or when Cut Tape packaging is compatible with assembly equipment.

PDZ16B,135 (Substitute): Supplied in Tape & Reel format. Select this part number as an alternative source when PDZ16B-QZ availability is limited.

All parts maintain active production status, AEC-Q101 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating. No electrical re-qualification or design changes are required when substituting between these part numbers.

Frequently Asked Questions (FAQ)

Q: Are PDZ16B,115 and PDZ16B,135 direct replacements for PDZ16B-QZ?

A: Yes. All three part numbers are parametric equivalents with identical electrical specifications (16 V nominal, 400 mW, ±2% tolerance) and mechanical compatibility in the SOD-323 package. The only difference is packaging format.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) is standard continuous reel packaging for high-volume automated assembly. Cut Tape (CT) is individual tape segments for smaller quantities. Digi-Reel® is an alternative reel format. All formats contain the same component and are compatible with standard surface mount assembly equipment.

Q: Can I use PDZ16B,115 if my assembly line requires Tape & Reel format?

A: PDZ16B,115 is supplied in Cut Tape and Digi-Reel® format. If your process requires standard Tape & Reel format, use PDZ16B-QZ or PDZ16B,135 instead.

Q: Do these parts require different handling or storage procedures?

A: No. All three part numbers have identical Moisture Sensitivity Level (MSL 1 - Unlimited), indicating no special moisture control is required during storage or handling.

Q: Are all three parts qualified to AEC-Q101?

A: The main part PDZ16B-QZ is explicitly qualified to AEC-Q101 automotive standards. The substitute parts PDZ16B,115 and PDZ16B,135 are manufactured by the same supplier with identical electrical and mechanical specifications, maintaining automotive-grade compliance.

Q: What is the inventory status for each part number?

A: PDZ16B-QZ: 696 pcs in stock. PDZ16B,115: 16,924 pcs in stock. PDZ16B,135: 10,344 pcs in stock. Inventory levels are subject to change based on current supply conditions.

Q: Can I mix part numbers within a single production batch?

A: Yes. Since all three part numbers are parametric equivalents with identical electrical performance and mechanical compatibility, they can be used interchangeably within the same circuit design and production batch without affecting circuit functionality or reliability.
