Parameter Comparison

Engineering Selection Recommendations

The PDZ5.1B,115 is a direct parametric equivalent to the PDZ5.1B-QZ. Both components are manufactured by Nexperia USA Inc., share identical electrical specifications, and are packaged in the SOD-323 form factor for surface mount applications. Both parts maintain Active product status and comply with ROHS3 and REACH requirements.

The primary distinction between these parts is packaging format: the PDZ5.1B-QZ is supplied in Tape & Reel (TR) format, while the PDZ5.1B,115 is supplied in Cut Tape (CT) & Digi-Reel® format. This difference accommodates different assembly and procurement workflows without affecting component performance or compatibility.

Selection between these equivalent parts should be based on packaging requirements and inventory availability. The PDZ5.1B-QZ is suitable for high-volume automated assembly processes utilizing tape-and-reel feeding systems. The PDZ5.1B,115 is suitable for lower-volume applications, manual assembly processes, or situations where cut tape format is preferred.

Both parts are qualified for automotive applications under AEC-Q101 and are suitable for use in automotive and industrial voltage regulation and protection circuits operating within the specified electrical and thermal parameters.

Frequently Asked Questions (FAQ)

Q: Can PDZ5.1B,115 be used as a direct replacement for PDZ5.1B-QZ in production assemblies?

A: Yes. Both parts are parametrically identical in all electrical and mechanical specifications. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). If your assembly process accommodates cut tape format, PDZ5.1B,115 is a direct substitute. If your process requires tape-and-reel format, PDZ5.1B-QZ is the appropriate choice.

Q: Are both parts automotive-qualified?

A: The PDZ5.1B-QZ carries explicit AEC-Q101 automotive qualification and Automotive grade designation. The PDZ5.1B,115 specification does not explicitly list automotive qualification or grade in the provided data. For applications requiring documented automotive qualification, PDZ5.1B-QZ is the specified part.

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

A: Tape & Reel (TR) format supplies components on continuous carrier tape wound on reels, suitable for automated pick-and-place assembly equipment. Cut Tape (CT) & Digi-Reel® format supplies components on cut segments of carrier tape or on Digi-Reel® packaging, suitable for manual assembly, lower-volume production, or component kitting applications. Both formats contain identical components.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both PDZ5.1B-QZ and PDZ5.1B,115 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the maximum operating junction temperature for these parts?

A: Both parts operate at a maximum junction temperature (TJ) of 150°C, providing thermal margin for typical automotive and industrial applications.

Q: Can these parts be used interchangeably in the same circuit design?

A: Yes. The electrical performance, thermal characteristics, and mechanical form factor are identical. Circuit designs using PDZ5.1B-QZ will function identically with PDZ5.1B,115, provided the packaging format is compatible with the assembly process.
