PDZ12B/ZLX Zener Diode Equivalent & Substitute Parts

Part Overview

The PDZ12B/ZLX is a Zener diode manufactured by NXP USA Inc., classified as an active product in the Diodes, Zener category. This component is a surface mount device in SOD-323 package format, designed for voltage regulation and protection applications requiring a 12V nominal Zener voltage. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained within the specified parameter tolerances. The availability of alternative sources and packaging options necessitates clear substitution guidance for procurement and design flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PDZ12B/ZLX is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Zener voltage nominal rating: 12 V
• Package type: SOD-323 (SC-76)
• Mounting type: Surface Mount
• Power dissipation capability: 400 mW minimum
• Voltage tolerance: ±2%
• Product status: Active
• Compliance: ROHS3 Compliant, REACH Unaffected

The direct substitute PDZ12B,115 (Nexperia USA Inc.) meets all specified criteria. Both the main part and substitute share the same base product number (PDZ12), confirming functional equivalence. Additional substitute candidates (UDZVTE-1712B, BZT52C12S-7-F, MM3Z12VST1G) are identified through the PDZ12B,115 substitution chain and maintain the same electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PDZ12B,115 (Nexperia USA Inc.)

The PDZ12B,115 is the direct equivalent substitute for PDZ12B/ZLX. Both components share identical base product number (PDZ12), package format (SOD-323), and compliance certifications (ROHS3, REACH Unaffected). Both maintain active product status, ensuring continued availability and manufacturing support. The substitute is available in Cut Tape (CT) and Digi-Reel® packaging options, providing procurement flexibility.

Secondary Substitutes: UDZVTE-1712B, BZT52C12S-7-F, MM3Z12VST1G

These components are identified as substitutes through the PDZ12B,115 substitution chain. Selection of secondary substitutes requires verification that all electrical parameters (Zener voltage 12V, power rating 400mW, tolerance ±2%) and mechanical specifications (SOD-323 package, surface mount) align with application requirements.

Compliance Considerations

All identified substitutes maintain ROHS3 compliance and REACH Unaffected status. MSL 1 (Unlimited) rating applies across all options, eliminating moisture sensitivity constraints in storage and handling.

Frequently Asked Questions (FAQ)

Q: Can PDZ12B,115 directly replace PDZ12B/ZLX in existing designs?

A: Yes. Both components share the same base product number (PDZ12), package format (SOD-323), and electrical specifications (12V Zener voltage, 400mW power rating, ±2% tolerance). No design modifications are required for direct substitution.

Q: What is the difference between PDZ12B/ZLX and PDZ12B,115?

A: The primary difference is manufacturer designation. PDZ12B/ZLX is manufactured by NXP USA Inc., while PDZ12B,115 is manufactured by Nexperia USA Inc. Both are functionally equivalent with identical electrical and mechanical parameters. Packaging options differ: PDZ12B,115 is available in Cut Tape (CT) and Digi-Reel® formats.

Q: Are the secondary substitutes (UDZVTE-1712B, BZT52C12S-7-F, MM3Z12VST1G) compatible with PDZ12B/ZLX?

A: Secondary substitutes maintain the same electrical specifications (12V Zener voltage, 400mW power rating, ±2% tolerance) and SOD-323 package format. Compatibility is confirmed for applications requiring these parameters. Specific device characteristics such as impedance, leakage current, and forward voltage should be reviewed against application requirements.

Q: What packaging options are available for substitutes?

A: PDZ12B,115 is supplied in Cut Tape (CT) and Digi-Reel® packaging. The main part PDZ12B/ZLX packaging format is not specified in available data. Packaging selection should align with assembly process requirements and inventory management practices.

Q: Are all substitutes ROHS3 compliant?

A: Yes. PDZ12B/ZLX and PDZ12B,115 both maintain ROHS3 compliance. Compliance status for secondary substitutes (UDZVTE-1712B, BZT52C12S-7-F, MM3Z12VST1G) should be verified through respective manufacturer documentation.

Q: What is the moisture sensitivity rating for these components?

A: Both PDZ12B/ZLX and PDZ12B,115 carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. Standard handling and storage practices apply without special precautions.
