Substitute Part Grouping Explanation

Substitute parts for the PDZ15B-QZ are identified based on electrical parameter equivalence and mechanical compatibility. The substitution logic is determined by the following criteria:

Electrical Parameters (Must Match):

Voltage - Zener (Nom): 15 V
Tolerance: ±2%
Power - Max: 400 mW
Impedance (Max): 15 Ohms
Current - Reverse Leakage @ Vr: 50 nA @ 11 V
Voltage - Forward (Vf) (Max) @ If: 1.1 V @ 100 mA
Operating Temperature: 150°C (TJ)

Mechanical Parameters (Must Match):

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

Allowed Variation:

Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel®) does not affect electrical or mechanical compatibility

All substitute parts listed maintain identical electrical performance and physical form factor, differing only in supply packaging configuration.

Engineering Selection Recommendations

All three parts—PDZ15B-QZ, PDZ15B,115, and PDZ15B,135—are Active products from Nexperia USA Inc. with identical electrical specifications and mechanical form factors. Selection between these parts is determined by packaging and supply requirements rather than circuit performance.

PDZ15B-QZ is supplied in Tape & Reel (TR) format with 770 pieces in stock.

PDZ15B,115 is supplied in Cut Tape (CT) & Digi-Reel® format with 21,046 pieces in stock, offering higher availability for smaller quantity requirements or alternative handling methods.

PDZ15B,135 is supplied in Tape & Reel (TR) format with 18,643 pieces in stock, matching the packaging format of the main part number.

All parts carry ROHS3 compliance, AEC-Q101 automotive qualification (where specified), and MSL Level 1 rating. Direct substitution is supported across all three part numbers without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can PDZ15B,115 replace PDZ15B-QZ in production assembly?

A: Yes. PDZ15B,115 is electrically and mechanically equivalent to PDZ15B-QZ. The difference is packaging format: PDZ15B,115 uses Cut Tape & Digi-Reel® while PDZ15B-QZ uses Tape & Reel. Both are surface mount components in SOD-323 package with identical electrical parameters. Assembly equipment compatibility depends on your specific tape handling system.

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

A: Tape & Reel (TR) supplies components on continuous carrier tape wound on a reel, suitable for high-volume automated assembly. Cut Tape (CT) & Digi-Reel® provides components on cut tape segments with optional reel packaging, suitable for lower-volume orders or mixed component requirements. Electrical and mechanical specifications are identical.

Q: Are all three parts suitable for automotive applications?

A: PDZ15B-QZ carries explicit Automotive grade designation with AEC-Q101 qualification. PDZ15B,115 and PDZ15B,135 do not list explicit automotive grade in the provided specifications. Confirm automotive suitability requirements with your design specifications before substitution in automotive applications.

Q: Do these parts have the same moisture sensitivity rating?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use PDZ15B,135 instead of PDZ15B-QZ?

A: Yes. PDZ15B,135 is electrically and mechanically equivalent to PDZ15B-QZ. Both use Tape & Reel packaging format. The parts are direct substitutes with identical electrical performance and physical form factor.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected. PDZ15B-QZ carries AEC-Q101 automotive qualification. Verify specific compliance requirements for your application before final part selection.
