Substitute Part Grouping Explanation

Substitution of the PDZ2.4B-QZ is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Substitution Parameters:

Zener voltage: 2.4 V nominal
Tolerance: ±2%
Maximum power dissipation: 400 mW
Maximum impedance: 100 Ohms
Reverse leakage current: 50 µA @ 1 V
Forward voltage: 1.1 V @ 100 mA
Operating temperature: 150°C (TJ)
Package type: SOD-323 (SC-76)
Mounting configuration: Surface Mount

All identified substitute parts maintain these specifications without deviation. Substitutes differ only in product status (active versus obsolete) and packaging format (Tape & Reel versus standard packaging).

Engineering Selection Recommendations

PDZ2.4B-QX is the primary substitute for PDZ2.4B-QZ. This part maintains active product status with Nexperia USA Inc., carries automotive-grade qualification (AEC-Q101), and is available in Tape & Reel packaging format. The PDZ2.4B-QX is electrically and mechanically identical to the obsolete PDZ2.4B-QZ across all specified parameters.

PDZ2.4B,115 is an alternative substitute with identical electrical specifications and active product status. This part differs in packaging designation (Tape & Reel format) and lacks explicit automotive-grade designation in the provided data, though it maintains ROHS3 compliance and REACH unaffected status.

Both substitutes are suitable for direct replacement in applications where the PDZ2.4B-QZ was originally specified. Selection between PDZ2.4B-QX and PDZ2.4B,115 depends on procurement requirements, packaging preferences, and automotive qualification necessity for the end application.

Frequently Asked Questions (FAQ)

Q: Can PDZ2.4B-QX and PDZ2.4B,115 be used interchangeably with PDZ2.4B-QZ?

A: Yes. Both substitute parts maintain identical electrical parameters (2.4 V nominal Zener voltage, ±2% tolerance, 400 mW power rating, 100 Ohms maximum impedance) and mechanical specifications (SOD-323 package, surface mount configuration). Direct substitution is supported without circuit modification.

Q: What is the primary reason for substituting PDZ2.4B-QZ?

A: PDZ2.4B-QZ is classified as obsolete. PDZ2.4B-QX and PDZ2.4B,115 are active products from the same manufacturer, ensuring continued availability and supply chain support.

Q: Are there packaging differences between the substitute parts?

A: PDZ2.4B-QZ is supplied in standard packaging. Both PDZ2.4B-QX and PDZ2.4B,115 are supplied in Tape & Reel (TR) format. The physical component remains identical (SOD-323); only the delivery packaging differs.

Q: Does PDZ2.4B-QX include automotive qualification?

A: Yes. PDZ2.4B-QX carries AEC-Q101 qualification and automotive-grade designation. PDZ2.4B,115 does not list explicit automotive qualification in the provided specifications.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. PDZ2.4B-QZ, PDZ2.4B-QX, and PDZ2.4B,115 are all ROHS3 compliant and REACH unaffected.

Q: What is the moisture sensitivity level for these Zener diodes?

A: All three parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can these parts be used in automotive applications?

A: PDZ2.4B-QX is explicitly qualified for automotive use (AEC-Q101). PDZ2.4B,115 does not list automotive qualification in the provided data. Application requirements should determine which substitute is appropriate.
