Each part maintains ROHS3 compliance and MSL Level 1 rating, confirming suitability for standard manufacturing and storage conditions.

Selection between these parts is determined by availability and supply chain requirements rather than electrical or mechanical performance differences. The PDZ13B,115 variant offers the highest inventory availability at 47,787 pieces. The PDZ13B,135 variant provides 6,200 pieces in stock. The PDZ13B-QX primary part maintains 832 pieces in inventory.

All parts are qualified to AEC-Q101 automotive standards where applicable and carry identical REACH and ECCN classifications, confirming regulatory equivalence for international applications.

Frequently Asked Questions (FAQ)

Q: Can PDZ13B,115 and PDZ13B,135 be used interchangeably with PDZ13B-QX?

A: Yes. All three parts share identical electrical parameters including 13 V nominal Zener voltage, 400 mW maximum power dissipation, ±2% tolerance, and 10 Ohms maximum impedance. They are packaged in the same SOD-323 surface mount case and maintain equivalent forward voltage and reverse leakage characteristics.

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

A: The PDZ13B-QX carries explicit AEC-Q101 automotive qualification. The substitute parts PDZ13B,115 and PDZ13B,135 are manufactured by the same supplier with identical specifications and ROHS3 compliance. Confirmation of automotive qualification status for substitute parts should be obtained from the manufacturer datasheet if automotive application is required.

Q: Do all parts have the same moisture sensitivity rating?

A: Yes. All three parts carry MSL Level 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage, handling, or assembly.

Q: What is the difference between the part number suffixes (QX, ,115, ,135)?

A: The suffixes indicate different packaging or tape reel configurations within the same electrical specification family. The electrical and mechanical parameters remain identical across all variants.

Q: Can these parts be soldered using standard surface mount assembly processes?

A: Yes. All parts are surface mount components in SOD-323 package format, compatible with standard reflow soldering and pick-and-place assembly equipment.

Q: Are there any compliance or regulatory differences between these parts?

A: No. All three parts maintain identical ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, confirming equivalent regulatory standing for domestic and international applications.
