Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ15B-QF are identified based on electrical parameter equivalence and mechanical compatibility. The following criteria determine substitutability:

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

Compliance Parameters (Must Match):

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

The substitute parts PDZ15B,115 and PDZ15B,135 are parametric equivalents that differ only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel), which does not affect electrical performance or mechanical fit in the application.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PDZ15B-QF, PDZ15B,115, and PDZ15B,135—are manufactured by Nexperia USA Inc. and maintain identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements rather than electrical performance.

PDZ15B-QF is supplied in Tape & Reel (TR) format with 730 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.

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 AEC-Q101 automotive qualification, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), confirming suitability for automotive and industrial applications. Product status is active for all three variants, ensuring long-term availability and support.

Frequently Asked Questions (FAQ)

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

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

Q: What is the difference between PDZ15B,135 and PDZ15B,115?

A: Both parts are parametric equivalents with identical electrical specifications and SOD-323 package dimensions. The difference is packaging format: PDZ15B,135 is supplied in Tape & Reel (TR) format, while PDZ15B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on your procurement and assembly process requirements.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry automotive-grade classification and AEC-Q101 qualification, confirming suitability for automotive applications. They maintain identical operating temperature ratings (150°C TJ) and compliance certifications.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel, Cut Tape, or Digi-Reel®) affects only supply chain logistics and assembly handling. Electrical performance, thermal characteristics, and reliability are identical across all three part numbers.

Q: What is the significance of the ±2% tolerance specification?

A: The ±2% tolerance on the 15 V nominal Zener voltage indicates that the actual Zener voltage will fall within the range of 14.7 V to 15.3 V. This specification is identical across all three substitute parts, ensuring consistent voltage regulation performance in circuit applications.

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

A: No. All three parts are ROHS3 compliant, REACH unaffected, carry MSL 1 (unlimited moisture sensitivity), and maintain identical ECCN and HTSUS classifications. Compliance status is uniform across all variants.
