Substitute Part Grouping Explanation

Substitute parts for the PDZ13B,135 are classified into two categories based on electrical and mechanical parameter alignment:

Direct Equivalent (PDZ13B,115): This part maintains identical electrical specifications across all critical parameters: 13 V nominal Zener voltage, 400 mW maximum power, ±2% tolerance, 10 Ohms maximum impedance, and SOD-323 package. The difference is limited to packaging format (Tape & Reel variant designation). This part is fully interchangeable in all applications.

Similar Substitute (UDZVTE-1713B): This part shares the same 13 V nominal Zener voltage and reverse leakage current specification (100 nA @ 10 V), with surface mount technology and ROHS3 compliance. However, it differs in maximum power dissipation (200 mW versus 400 mW), impedance (37 Ohms versus 10 Ohms), and package designation (UMD2 versus SOD-323). This part is suitable for applications where the lower power rating and higher impedance are acceptable within circuit design margins.

Engineering Selection Recommendations

PDZ13B,115 Selection: This part is recommended as the primary substitute for the PDZ13B,135. Both parts are manufactured by Nexperia USA Inc., share identical electrical specifications, and maintain equivalent ROHS3 and REACH compliance status. The parts differ only in packaging format designation, making PDZ13B,115 a direct functional replacement with no circuit redesign required.

UDZVTE-1713B Selection: This part is suitable for applications where power dissipation requirements do not exceed 200 mW and where the higher impedance characteristic (37 Ohms) is compatible with circuit design parameters. The extended operating temperature range (-55°C to 150°C) provides additional thermal margin compared to the main part specification. ROHS3 and REACH compliance are maintained. Circuit validation is required to confirm impedance and power rating compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can PDZ13B,115 be used as a direct replacement for PDZ13B,135?

A: Yes. Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications: 13 V nominal Zener voltage, 400 mW maximum power, ±2% tolerance, 10 Ohms maximum impedance, and SOD-323 package. The parts differ only in packaging format designation and are fully interchangeable.

Q: What are the limitations of UDZVTE-1713B as a substitute?

A: The UDZVTE-1713B has a maximum power rating of 200 mW compared to 400 mW for the main part, and an impedance of 37 Ohms compared to 10 Ohms. These differences affect circuit performance in high-current or precision voltage regulation applications. Substitution is valid only when circuit design margins accommodate these parameter differences.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. Both PDZ13B,115 and UDZVTE-1713B are ROHS3 compliant and REACH unaffected, matching the compliance status of the main part PDZ13B,135.

Q: What is the difference between SOD-323 and UMD2 packages?

A: SOD-323 and UMD2 are different surface mount package designations. The main part and direct equivalent use SOD-323 (SC-76), while the similar substitute uses UMD2 (SC-90, SOD-323F). Physical dimensions and PCB footprints differ between these packages and require verification for mechanical compatibility.

Q: Is tolerance specification available for UDZVTE-1713B?

A: Tolerance specification is not provided in the available technical data for UDZVTE-1713B. The main part and direct equivalent specify ±2% tolerance. Confirmation of tolerance specifications from the manufacturer is required for precision applications.

Q: Can UDZVTE-1713B operate at lower temperatures than the main part?

A: Yes. UDZVTE-1713B specifies an operating temperature range of -55°C to 150°C, compared to 150°C maximum for the main part. This provides extended low-temperature capability for applications requiring operation below ambient conditions.
