• Zener voltage nominal (Vz): 6.8 V
• Power dissipation rating: 400 mW
• Voltage tolerance: ±2%
• Package type: SOD-323 (SC-76)
• Mounting type: Surface Mount

Compliance & Regulatory Parameters:

• RoHS3 compliance requirement
• REACH unaffected status
• ECCN classification: EAR99
• HTSUS code: 8541.10.0050
• MSL rating: 1 (Unlimited)

The substitute part PDZ6.8B,115 shares identical electrical specifications, package configuration, and regulatory compliance status, establishing direct functional equivalence for circuit design and procurement purposes.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

Both PDZ6.8B/ZLX and PDZ6.8B,115 are active products with identical regulatory compliance status (ROHS3 compliant, REACH unaffected, EAR99 classification). Both components share the same base product number (PDZ6.8) and package configuration (SOD-323 surface mount).

Compliance Verification:

• Both parts meet ROHS3 requirements for hazardous substance restrictions
• Both maintain REACH unaffected status, indicating no substance of very high concern (SVHC) designation
• Both are classified under ECCN EAR99, permitting standard commercial distribution
• Both carry MSL 1 rating, requiring no special moisture control during storage or handling

Inventory Considerations:

The substitute part PDZ6.8B,115 maintains significantly higher inventory availability (18200 Pcs versus 1014 Pcs), supporting supply chain continuity and reducing lead time risk for high-volume procurement scenarios.

Packaging Format:

The substitute part is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. This packaging format is standard for surface mount SOD-323 components in production environments.

Frequently Asked Questions (FAQ)

Q: Can PDZ6.8B,115 be used as a direct replacement for PDZ6.8B/ZLX in existing circuit designs?

A: Yes. Both components share identical base product number (PDZ6.8), package type (SOD-323), and regulatory compliance status. The electrical specifications provided for the substitute part (6.8 V nominal, 400 mW power rating, ±2% tolerance) establish functional equivalence for voltage regulation and protection applications.

Q: What is the difference between the two part numbers?

A: PDZ6.8B/ZLX and PDZ6.8B,115 represent different manufacturer designations and packaging configurations from NXP USA Inc. and Nexperia USA Inc. respectively. The suffix variation reflects packaging format (Tape & Reel for the substitute) and internal product coding. Both parts are derived from the same base product number (PDZ6.8).

Q: Are there any restrictions on using the substitute part in regulated industries?

A: Both parts carry identical regulatory classifications (ROHS3 compliant, REACH unaffected, EAR99). No additional restrictions apply to the substitute part beyond those applicable to the main part. Compliance status is equivalent for all regulatory frameworks covered by these certifications.

Q: What is the significance of the SOD-323 package for substitution purposes?

A: SOD-323 (SC-76) is the physical package standard for both components. This package type defines the footprint, lead configuration, and mounting method for surface mount assembly. Identical package specification ensures mechanical and electrical compatibility on printed circuit boards without design modification.

Q: Does the higher inventory level of PDZ6.8B,115 affect its technical performance?

A: No. Inventory level reflects supply availability and does not impact electrical performance, compliance status, or functional characteristics. The substitute part maintains identical specifications and regulatory compliance regardless of stock quantity.

Q: What does MSL 1 (Unlimited) mean for component handling?

A: MSL 1 rating indicates the component has unlimited shelf life and requires no special moisture control measures during storage, transportation, or handling. This classification applies equally to both the main part and substitute, simplifying logistics and inventory management.
