PDZ27B-QF Equivalent & Substitute Parts

Part Overview

The PDZ27B-QF is an active Zener diode manufactured by Nexperia USA Inc., designed for surface mount applications in the SOD-323 package. This component operates at a nominal Zener voltage of 27 V with a maximum power dissipation of 400 mW and is qualified to automotive standards (AEC-Q101). The part is ROHS3 compliant and carries an unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same functional category. Alternative part numbers may be required due to inventory availability, supply chain considerations, or specific procurement requirements while maintaining identical performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PDZ27B-QF are identified based on strict equivalence of the following electrical and mechanical parameters:

• Zener voltage: 27 V nominal
• Tolerance: ±2%
• Maximum power dissipation: 400 mW
• Maximum impedance: 40 Ohms
• Reverse leakage current: 50 nA @ 21 V
• Forward voltage: 1.1 V maximum @ 100 mA
• Junction temperature rating: 150°C
• Package type: SOD-323 (SC-76)
• Mounting configuration: Surface Mount
• Compliance standards: ROHS3, REACH Unaffected

Parts meeting all these parameters are classified as parametric equivalents and may be substituted without circuit redesign or performance degradation.

Parameter Comparison

Engineering Selection Recommendations

Both PDZ27B-QF and PDZ27B,115 are active products manufactured by Nexperia USA Inc. and maintain identical electrical and mechanical specifications. Both components are ROHS3 compliant, REACH unaffected, and carry automotive-grade qualification (AEC-Q101 for the primary part). The PDZ27B,115 variant is available with higher inventory levels (1211 pieces versus 709 pieces for PDZ27B-QF).

Selection between these parts is based on procurement availability and supply chain requirements. No performance differences exist between the two part numbers when applied to equivalent circuit designs. Both parts are suitable for automotive and industrial applications requiring 27 V Zener regulation at 400 mW power dissipation in surface mount configurations.

Frequently Asked Questions (FAQ)

Q: Can PDZ27B,115 be used as a direct replacement for PDZ27B-QF?

A: Yes. Both parts are parametric equivalents with identical electrical specifications, power ratings, impedance characteristics, and SOD-323 package dimensions. Direct substitution is supported without circuit modification.

Q: Are there differences in automotive qualification between these parts?

A: The PDZ27B-QF carries explicit AEC-Q101 automotive qualification. The PDZ27B,115 does not list this qualification in the provided specifications. Automotive applications requiring AEC-Q101 certification should use PDZ27B-QF.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Are the package dimensions identical?

A: Yes. Both parts use the SC-76 / SOD-323 surface mount package with identical footprint and land pattern requirements.

Q: What is the difference between PDZ27B-QF and PDZ27B,115 part numbering?

A: The suffix designations indicate different packaging or distribution configurations from Nexperia USA Inc. Both are supplied in Tape & Reel format. The numerical suffix (,115) represents an alternative part number variant within the same product family.

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

A: Yes, provided the application does not require specific AEC-Q101 certification. Both parts meet identical electrical and mechanical specifications and are compatible with the same PCB assembly processes.
