Substitute Part Grouping Explanation
Substitution of the PDZ6.2B-QF is determined by strict equivalence across the following critical parameters:
- Zener Voltage (Vz): 6.2 V nominal with ±2% tolerance
- Power Rating: 400 mW maximum
- Impedance (Zzt): 50 Ohms maximum
- Reverse Leakage Current: 500 nA @ 3 V
- Forward Voltage: 1.1 V maximum @ 100 mA
- Operating Temperature: 150°C junction temperature
- Package Type: SOD-323 surface mount
- Compliance: ROHS3, AEC-Q101 automotive qualification
The substitute part PDZ6.2B,115 maintains identical electrical specifications and package compatibility. The difference between these part numbers reflects alternative packaging formats (Tape & Reel versus Cut Tape & Digi-Reel®) rather than functional or electrical divergence.

Engineering Selection Recommendations
Both PDZ6.2B-QF and PDZ6.2B,115 are Active products manufactured by Nexperia USA Inc. with identical electrical and mechanical specifications. Selection between these parts is determined by supply chain and packaging requirements rather than functional performance.
PDZ6.2B-QF is supplied in Tape & Reel format, suitable for high-volume automated assembly operations.
PDZ6.2B,115 is supplied in Cut Tape & Digi-Reel® format, suitable for mixed-volume production or component kit applications.
Both parts carry AEC-Q101 automotive qualification and ROHS3 compliance, confirming suitability for automotive and regulated applications. The SOD-323 package footprint is identical across both variants, requiring no PCB layout modifications during substitution.
Frequently Asked Questions (FAQ)
Q: Can PDZ6.2B,115 be used as a direct replacement for PDZ6.2B-QF in production?
A: Yes. Both parts are electrically and mechanically equivalent. The difference is packaging format only. PDZ6.2B-QF arrives in Tape & Reel format, while PDZ6.2B,115 arrives in Cut Tape & Digi-Reel® format. PCB assembly equipment compatibility should be verified based on your specific feeder configuration.
Q: Are there any differences in the SOD-323 package footprint between these parts?
A: No. Both parts use the SC-76, SOD-323 package with identical mechanical dimensions and land pattern requirements. No PCB redesign is necessary when substituting between these part numbers.
Q: Do both parts meet automotive qualification requirements?
A: Yes. Both PDZ6.2B-QF and PDZ6.2B,115 carry AEC-Q101 qualification and are rated for automotive applications. Operating temperature range and reliability specifications are identical.
Q: What is the difference between the part numbers PDZ6.2B-QF and PDZ6.2B,115?
A: The part number suffix indicates the packaging format and distribution channel. PDZ6.2B-QF specifies Tape & Reel packaging, while PDZ6.2B,115 specifies Cut Tape & Digi-Reel® packaging. Electrical specifications and device performance are identical.
Q: Are moisture sensitivity levels the same for both parts?
A: Yes. Both parts have Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.
Q: Can I mix PDZ6.2B-QF and PDZ6.2B,115 in the same production run?
A: Yes, provided your assembly equipment can accommodate both packaging formats. Since electrical and mechanical specifications are identical, mixed sourcing does not affect circuit performance or reliability.
