PDZ15B-QX Equivalent & Substitute Parts

Part Overview

The PDZ15B-QX is a Zener diode manufactured by Nexperia USA Inc., classified as a surface mount semiconductor component in the SOD-323 package. This 15 V, 400 mW Zener diode is designed for voltage regulation and protection applications in electronic circuits. The part is currently in active production status with full automotive qualification under AEC-Q101 standards. Substitute parts are identified when packaging formats differ or when inventory availability requires alternative sourcing while maintaining identical electrical performance and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ15B-QX are identified based on electrical parameter equivalence and compliance certification alignment. The substitution logic is determined by the following criteria:

Electrical Parameters (Must Match):

• Voltage - Zener (Nominal): 15 V
• Tolerance: ±2%
• Power - Maximum: 400 mW
• Impedance (Maximum): 15 Ohms
• Current - Reverse Leakage @ 11 V: 50 nA
• Voltage - Forward (Maximum) @ 100 mA: 1.1 V
• Operating Temperature (Junction): 150°C

Mechanical Parameters (Must Match):

• Package / Case: SC-76, SOD-323
• Mounting Type: Surface Mount
• Supplier Device Package: SOD-323

Compliance Parameters (Must Match):

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Manufacturer: Nexperia USA Inc.

Variable Parameter (Allows Substitution):

• Packaging Format: Tape & Reel (TR), Cut Tape (CT) & Digi-Reel®

The PDZ15B-QX and its substitutes differ only in packaging and delivery format, not in electrical or mechanical specifications. All substitute parts maintain identical performance characteristics and automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PDZ15B-QX, PDZ15B,115, and PDZ15B,135—are functionally equivalent for circuit design purposes. Selection between these parts is determined by procurement and assembly requirements rather than electrical performance.

PDZ15B-QX (Tape & Reel): Primary selection for high-volume automated assembly operations. Tape & Reel packaging is optimized for pick-and-place equipment and provides efficient component feeding in production environments.

PDZ15B,115 (Cut Tape & Digi-Reel®): Alternative selection when smaller quantities are required or when mixed component sourcing is necessary. Cut Tape format accommodates manual assembly and lower-volume production runs. Digi-Reel® packaging provides flexible quantity options.

PDZ15B,135 (Tape & Reel): Alternative Tape & Reel option with identical specifications to PDZ15B-QX. Selection between PDZ15B-QX and PDZ15B,135 is based on inventory availability and supplier lead times, as both are functionally and mechanically interchangeable.

All parts carry active product status, full AEC-Q101 automotive qualification, ROHS3 compliance, and REACH unaffected designation. No electrical or thermal performance differences exist between these parts. Component selection should be based on packaging format compatibility with assembly equipment and procurement availability.

Frequently Asked Questions (FAQ)

Q: Can PDZ15B,115 be used as a direct replacement for PDZ15B-QX in automated assembly?

A: PDZ15B,115 uses Cut Tape & Digi-Reel® packaging, which is not compatible with standard tape-fed pick-and-place equipment designed for Tape & Reel format. For automated assembly requiring Tape & Reel packaging, use PDZ15B-QX or PDZ15B,135. PDZ15B,115 is suitable for manual assembly or semi-automated processes.

Q: Are there electrical performance differences between PDZ15B-QX and PDZ15B,135?

A: No. Both parts have identical electrical specifications, including 15 V nominal Zener voltage, ±2% tolerance, 400 mW maximum power, 15 Ohms maximum impedance, and all other rated parameters. The only difference is packaging format, which does not affect circuit performance.

Q: Do all three parts meet automotive qualification requirements?

A: The PDZ15B-QX carries explicit AEC-Q101 automotive qualification designation. PDZ15B,115 and PDZ15B,135 are manufactured by Nexperia USA Inc. with identical electrical and mechanical specifications, ROHS3 compliance, and REACH unaffected status. Confirm specific automotive qualification requirements with your design documentation.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® packaging provides components on cut tape segments or flexible reel formats, suitable for manual assembly, lower-volume production, or mixed-component sourcing scenarios.

Q: Can I substitute PDZ15B,115 for PDZ15B-QX if I modify my assembly process?

A: Substitution is possible only if your assembly process is modified to accommodate Cut Tape & Digi-Reel® format. This requires manual component handling or semi-automated equipment capable of processing cut tape. Verify that your production workflow supports this packaging format before implementing substitution.

Q: Are moisture sensitivity levels identical across all three parts?

A: Yes. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture-related storage or handling restrictions. Standard component storage conditions apply to all variants.

Q: What inventory levels are available for each part?

A: PDZ15B-QX has 683 pieces in stock. PDZ15B,115 has 21,046 pieces in stock. PDZ15B,135 has 18,643 pieces in stock. Inventory availability may influence part selection when lead times are critical.
