PDZ7.5B-QF Equivalent & Substitute Parts

Part Overview

The PDZ7.5B-QF is a Zener diode manufactured by Nexperia USA Inc., designed for voltage regulation and protection applications requiring a nominal Zener voltage of 7.5 V with 400 mW power dissipation capability. This component is classified as an Active product and carries automotive-grade qualification under AEC-Q101 standards. The part is supplied in Tape & Reel (TR) packaging with SOD-323 surface mount configuration.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same product family, enabling design flexibility and supply chain optimization without circuit redesign.

Substitute Part Grouping Explanation

Substitution of the PDZ7.5B-QF is permissible with the PDZ7.5B,115 based on strict equivalence of the following critical parameters:

Zener Voltage (Nominal): Both parts specify 7.5 V
Voltage Tolerance: Both parts maintain ±2% tolerance
Maximum Power Dissipation: Both parts rated at 400 mW
Maximum Impedance: Both parts specify 10 Ohms maximum
Reverse Leakage Current: Both parts specify 500 nA @ 4 V
Forward Voltage: Both parts specify 1.1 V maximum @ 100 mA
Operating Temperature: Both parts rated to 150°C (TJ)
Package Configuration: Both parts use SOD-323 surface mount package
Compliance Standards: Both parts are ROHS3 Compliant with MSL 1 (Unlimited)

The primary distinction between these parts is packaging format: PDZ7.5B-QF is supplied in Tape & Reel (TR) format, while PDZ7.5B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. This difference does not affect electrical performance or mechanical compatibility in the end application.

Engineering Selection Recommendations

Both PDZ7.5B-QF and PDZ7.5B,115 are Active products from Nexperia USA Inc. with identical electrical and thermal specifications. Selection between these parts is determined by procurement and assembly requirements rather than circuit performance:

PDZ7.5B-QF (Tape & Reel): Suitable for high-volume automated assembly operations requiring continuous reel feeding into pick-and-place equipment.

PDZ7.5B,115 (Cut Tape & Digi-Reel®): Suitable for lower-volume production runs, prototype builds, or applications where component-level flexibility is required.

Both parts maintain ROHS3 compliance, AEC-Q101 automotive qualification (PDZ7.5B-QF), and unlimited moisture sensitivity level (MSL 1), ensuring compatibility with standard surface mount assembly processes and environmental requirements.

Frequently Asked Questions (FAQ)

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

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format only. PDZ7.5B,115 in Cut Tape format requires manual or semi-automated component handling, while PDZ7.5B-QF in Tape & Reel format integrates directly with automated reel-fed assembly systems.

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

A: No. Both parts specify identical Zener voltage (7.5 V), tolerance (±2%), maximum power (400 mW), impedance (10 Ohms), reverse leakage current (500 nA @ 4 V), and forward voltage (1.1 V @ 100 mA).

Q: Do both parts fit the same PCB footprint?

A: Yes. Both parts use the SOD-323 surface mount package (SC-76 case), which defines identical lead spacing and pad dimensions.

Q: Are both parts suitable for automotive applications?

A: PDZ7.5B-QF carries AEC-Q101 automotive qualification. PDZ7.5B,115 does not list AEC-Q101 qualification in the provided specifications. For automotive applications requiring AEC-Q101 certification, PDZ7.5B-QF is the specified part.

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

A: Tape & Reel (TR) packaging supplies components on a continuous reel suitable for automated pick-and-place machines. Cut Tape (CT) & Digi-Reel® packaging supplies components in shorter tape segments or alternative reel formats, typically for lower-volume or manual assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both PDZ7.5B-QF and PDZ7.5B,115 are ROHS3 Compliant with REACH Unaffected status.
