Substitute Part Grouping Explanation

Substitution of the PDZ9.1B-QZ with the PDZ9.1B,115 is based on parametric equivalence across all critical electrical and mechanical specifications. Both parts share identical Zener voltage (9.1 V), tolerance (±2%), maximum power rating (400 mW), impedance characteristics (10 Ohms maximum), reverse leakage current (500 nA @ 6 V), forward voltage drop (1.1 V @ 100 mA), and operating temperature range (150°C junction temperature). Both components utilize the SOD-323 surface mount package and maintain the same automotive-grade classification with AEC-Q101 qualification. The primary distinction between these parts is packaging format: PDZ9.1B-QZ is supplied in Tape & Reel format, while PDZ9.1B,115 is supplied in Cut Tape and Digi-Reel format. Both maintain identical RoHS3 compliance, unlimited moisture sensitivity level (MSL 1), and REACH unaffected status. The substitution is valid for applications where packaging format does not impose constraints on assembly or procurement workflows.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ9.1B-QZ and PDZ9.1B,115 are Active products from Nexperia USA Inc. with identical electrical specifications and automotive-grade AEC-Q101 qualification. Selection between these parts should be based on packaging format requirements and procurement constraints. The PDZ9.1B-QZ in Tape & Reel format is suitable for high-volume automated assembly operations requiring continuous reel feeding. The PDZ9.1B,115 in Cut Tape and Digi-Reel format provides flexibility for mixed-volume production runs and component kit assembly. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity level, eliminating environmental or regulatory constraints as differentiating factors. The identical electrical performance, impedance characteristics, and thermal ratings ensure direct functional interchangeability in circuit applications. Selection should prioritize inventory availability, assembly equipment compatibility, and supply chain lead times without compromising electrical performance or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can PDZ9.1B,115 be used as a direct replacement for PDZ9.1B-QZ in automotive applications?

A: Yes. Both parts are manufactured by Nexperia USA Inc., carry AEC-Q101 automotive qualification, and possess identical electrical specifications including 9.1 V nominal Zener voltage, 400 mW power rating, 10 Ohms maximum impedance, and 150°C operating temperature. The only difference is packaging format (Tape & Reel versus Cut Tape/Digi-Reel), which does not affect electrical performance or circuit functionality.

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

A: Tape & Reel (TR) packaging supplies components on continuous reels suitable for automated pick-and-place assembly systems. Cut Tape (CT) and Digi-Reel packaging provide components in smaller quantities or alternative reel formats, offering flexibility for lower-volume production or component kit assembly. Both formats contain identical components with no electrical differences.

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

A: No. Both PDZ9.1B-QZ and PDZ9.1B,115 maintain identical RoHS3 compliance, REACH unaffected status, and AEC-Q101 automotive qualification. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since both parts are electrically identical and carry the same certifications and qualifications, they can be used interchangeably within the same circuit design and production batch without affecting performance, reliability, or compliance.

Q: What inventory considerations apply to these substitute parts?

A: PDZ9.1B-QZ is available with 766 pieces in stock, while PDZ9.1B,115 has 6300 pieces in stock. Selection may be influenced by immediate availability requirements and supply chain lead times.
