Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ3.6B-QZ is determined by the following critical parameters: Zener voltage (Vz), power rating, impedance, package type, and automotive qualification status. The substitute parts are grouped into two categories based on these criteria:

Parametric Equivalents (Identical Zener Voltage): Parts maintaining the 3.6 V nominal Zener voltage with matching 400 mW power rating, 90 Ohms impedance, and SOD-323 package. These parts are direct functional replacements.

Manufacturer Recommended Substitute (Voltage Variant): The PDZ3.6B-QX and PDZ3.3B-QX represent alternative voltage ratings within the same product family. The PDZ3.3B-QX operates at 3.3 V nominal Zener voltage with 95 Ohms impedance, suitable for applications where lower voltage regulation is acceptable.

All substitute parts maintain identical mounting type (Surface Mount), package format (SOD-323), operating temperature range (150°C), and automotive compliance (AEC-Q101, ROHS3).

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Electrical Performance):

The PDZ3.6B-QX is the primary substitute for the obsolete PDZ3.6B-QZ. Both parts maintain identical Zener voltage (3.6 V), power rating (400 mW), impedance (90 Ohms), and automotive qualification (AEC-Q101). The PDZ3.6B-QX is currently in Active product status with 769 units in stock. This part is packaged in Tape & Reel format and carries ROHS3 compliance.

The PDZ3.6B,115 provides parametric equivalence with identical electrical specifications and is available in higher inventory (25,301 units). This part is manufactured by NXP Semiconductors and maintains the same SOD-323 package and operating temperature range. Automotive grade and AEC-Q101 qualification status are not specified for this variant.

For Voltage-Variant Applications:

The PDZ3.3B-QX operates at 3.3 V nominal Zener voltage with marginally higher impedance (95 Ohms versus 90 Ohms). This part is suitable only for applications where 3.3 V regulation is functionally acceptable. The PDZ3.3B-QX maintains automotive grade, AEC-Q101 qualification, and ROHS3 compliance with 656 units in stock.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and REACH Unaffected status. For automotive applications requiring AEC-Q101 qualification, the PDZ3.6B-QX and PDZ3.3B-QX are qualified options. The PDZ3.6B,115 does not specify automotive grade or AEC-Q101 qualification in the provided data.

Frequently Asked Questions (FAQ)

Q: Can the PDZ3.6B-QX be used as a direct replacement for the PDZ3.6B-QZ?

A: Yes. The PDZ3.6B-QX is a direct parametric equivalent with identical Zener voltage (3.6 V), power rating (400 mW), impedance (90 Ohms), and package format (SOD-323). Both parts are automotive-grade with AEC-Q101 qualification. The primary difference is product status: PDZ3.6B-QZ is Obsolete while PDZ3.6B-QX is Active.

Q: What is the difference between PDZ3.6B-QX and PDZ3.6B,115?

A: Both parts maintain identical electrical specifications (3.6 V, 400 mW, 90 Ohms impedance, SOD-323 package). The PDZ3.6B-QX is manufactured by Nexperia USA Inc. with documented automotive grade and AEC-Q101 qualification. The PDZ3.6B,115 is manufactured by NXP Semiconductors with higher inventory availability (25,301 units). Automotive qualification status is not specified for PDZ3.6B,115.

Q: Can the PDZ3.3B-QX replace the PDZ3.6B-QZ?

A: The PDZ3.3B-QX is not a direct replacement due to different Zener voltage (3.3 V versus 3.6 V). This part is suitable only for applications where 3.3 V regulation is functionally acceptable. The impedance is also slightly higher (95 Ohms versus 90 Ohms). All other parameters including power rating, package, and automotive qualification are equivalent.

Q: Are all substitute parts available in the same package format?

A: Yes. All substitute parts (PDZ3.6B-QX, PDZ3.6B,115, and PDZ3.3B-QX) use the SOD-323 package with Surface Mount mounting type, identical to the PDZ3.6B-QZ. No package conversion or board layout modification is required.

Q: What is the moisture sensitivity level for these parts?

A: All parts maintain Moisture Sensitivity Level (MSL) 1, indicating Unlimited shelf life without moisture control requirements.

Q: Are these parts RoHS compliant?

A: The PDZ3.6B-QX and PDZ3.3B-QX are ROHS3 Compliant. The PDZ3.6B-QZ is also ROHS3 Compliant. RoHS status is not specified for PDZ3.6B,115 in the provided data.
