Substitute Part Grouping Explanation

The PDZ7.5B-QZ and its identified substitute PDZ7.5B,115 are classified as parametric equivalents based on identical electrical and mechanical specifications. Substitution is valid when the following criteria are met:

Critical Matching Parameters:

• Voltage - Zener (Nom): 7.5 V
• Tolerance: ±2%
• Power - Max: 400 mW
• Impedance (Max): 10 Ohms
• Current - Reverse Leakage @ Vr: 500 nA @ 4 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

The primary distinction between these parts is the packaging format: PDZ7.5B-QZ is supplied in Tape & Reel (TR) format, while PDZ7.5B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. Both parts maintain identical electrical performance and physical dimensions, permitting direct substitution in circuit applications where packaging format does not impose constraints.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ7.5B-QZ and PDZ7.5B,115 are Active products manufactured by Nexperia USA Inc. and carry identical electrical specifications. Selection between these parts is determined by packaging and supply chain requirements rather than electrical performance.

PDZ7.5B-QZ is appropriate for high-volume automated assembly operations requiring Tape & Reel packaging format, which facilitates continuous pick-and-place machine processing.

PDZ7.5B,115 is appropriate for applications requiring Cut Tape or Digi-Reel® packaging formats, which support lower-volume production runs, manual assembly processes, or alternative distribution channels.

Both parts satisfy automotive-grade requirements through AEC-Q101 qualification and maintain full compliance with ROHS3 and REACH regulations. Moisture sensitivity classification of MSL 1 (Unlimited) indicates no special storage or handling requirements beyond standard component handling practices.

Frequently Asked Questions (FAQ)

Q: Can PDZ7.5B,115 be used as a direct replacement for PDZ7.5B-QZ in production assembly?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics and physical dimensions. The primary difference is packaging format. If your assembly process accommodates Cut Tape or Digi-Reel® packaging, PDZ7.5B,115 is a valid substitute. If your process requires Tape & Reel format, PDZ7.5B-QZ is the appropriate selection.

Q: Are there any electrical performance differences between these two part numbers?

A: No. Both parts maintain identical Zener voltage (7.5 V), power rating (400 mW), impedance (10 Ohms maximum), reverse leakage current (500 nA @ 4 V), and forward voltage characteristics (1.1 V @ 100 mA). Operating temperature range is identical at 150°C (TJ).

Q: Do both parts meet automotive qualification standards?

A: Yes. Both PDZ7.5B-QZ and PDZ7.5B,115 carry AEC-Q101 automotive-grade qualification and are classified as Automotive grade components.

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

A: Tape & Reel (TR) packaging supplies components on continuous carrier tape wound on reels, optimized for automated high-speed assembly equipment. Cut Tape (CT) and Digi-Reel® packaging supply components on shorter tape segments or alternative formats, suitable for lower-volume production, manual assembly, or component distribution through alternative channels.

Q: Are moisture sensitivity precautions required for either part?

A: No. Both parts carry Moisture Sensitivity Level (MSL) classification of 1 (Unlimited), indicating no special moisture control measures are required during storage or handling beyond standard component handling practices.

Q: Can these parts be used interchangeably in circuit designs?

A: Yes. The identical electrical specifications, physical dimensions (SOD-323 package), and surface mount configuration permit direct circuit-level substitution. Component selection should be based on packaging format availability and supply chain requirements.
