Substitute Part Grouping Explanation

Substitution of the PDZ9.1B-QF with PDZ9.1B,115 is based on electrical and mechanical parameter equivalence. Both devices share identical specifications across all critical performance criteria: 9.1 V nominal Zener voltage, ±2% tolerance, 400 mW maximum power dissipation, 10 Ohms maximum impedance, 500 nA reverse leakage current at 6 V, and 1.1 V maximum forward voltage at 100 mA. Both devices operate at 150°C maximum junction temperature, employ SOD-323 surface mount packaging, and maintain Automotive grade classification with AEC-Q101 qualification. The primary distinction between these parts is packaging format: PDZ9.1B-QF is supplied in Tape & Reel (TR) configuration, while PDZ9.1B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. Both maintain identical RoHS3 compliance, MSL 1 rating, and REACH Unaffected status. Substitution is valid when packaging format requirements permit the alternative supply method.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ9.1B-QF and PDZ9.1B,115 are Active status products manufactured by Nexperia USA Inc. and maintain full compliance with automotive industry standards through AEC-Q101 qualification. Both devices satisfy RoHS3 requirements and carry MSL 1 (Unlimited) moisture sensitivity classification, indicating no special handling requirements during storage or assembly. Selection between these parts is determined by packaging format requirements and supply chain logistics rather than electrical performance or compliance considerations. The PDZ9.1B-QF in Tape & Reel format is suitable for high-volume automated assembly operations, while the PDZ9.1B,115 in Cut Tape & Digi-Reel® format accommodates lower-volume production runs or component kit assembly. Both parts are suitable for direct substitution in automotive-grade voltage regulation and protection circuits where 9.1 V Zener voltage and 400 mW power dissipation specifications are required.

Frequently Asked Questions (FAQ)

Q: Can PDZ9.1B,115 be used as a direct replacement for PDZ9.1B-QF in production assembly?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters. The only difference is packaging format. If your assembly process accommodates Cut Tape & Digi-Reel® packaging, PDZ9.1B,115 is a valid direct substitute.

Q: Are there any performance differences between Tape & Reel and Cut Tape packaging formats?

A: No. The electrical performance, thermal characteristics, and reliability of the diode itself are independent of packaging format. Packaging format affects only supply chain handling, storage, and automated placement equipment compatibility.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both PDZ9.1B-QF and PDZ9.1B,115 carry Automotive grade classification and AEC-Q101 qualification. Both are suitable for automotive applications requiring 9.1 V Zener voltage regulation.

Q: What is the significance of MSL 1 (Unlimited) rating for both parts?

A: MSL 1 indicates the lowest moisture sensitivity level. Both parts require no special moisture control during storage, handling, or assembly. Standard warehouse conditions are acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes. Both PDZ9.1B-QF and PDZ9.1B,115 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the base product number for these parts?

A: The base product number is PDZ9.1. Both PDZ9.1B-QF and PDZ9.1B,115 are variants of this base product, differentiated by packaging format and tolerance grade.
