Key Parameters

Substitute Part Grouping Explanation

Substitution of Zener diodes within the BZX84W series is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Nominal Zener voltage (Vz) must be 3 V
• Maximum power dissipation must be 275 mW
• Maximum impedance (Zzt) must not exceed 95 Ohms
• Reverse leakage current must not exceed 10 µA @ 1 V
• Forward voltage must not exceed 900 mV @ 10 mA

Mechanical Compatibility Criteria:

• Package type must be SC-70 / SOT-323
• Mounting type must be Surface Mount
• Supplier device package must be SOT-323

Tolerance Variations: Substitute parts are grouped by voltage tolerance specification. The BZX84W-C3V0F operates at ±5% tolerance. Substitute parts with tighter tolerance specifications (±2%) are electrically compatible and represent improved performance within the same functional class. Parts with identical tolerance specifications (±5%) provide direct equivalence.

Packaging Variants: The suffix designation (F or X) indicates packaging format within Tape & Reel (TR) delivery. Both variants meet the same electrical and mechanical specifications and are interchangeable at the component level.

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Nexperia USA Inc. and maintain ROHS3 compliance and REACH unaffected status. Selection between the BZX84W-C3V0F and its substitutes is based on the following criteria:

Direct Equivalence (BZX84W-C3V0X): The BZX84W-C3V0X is a direct electrical and mechanical equivalent with identical tolerance specification (±5%). This part differs only in packaging format designation and is suitable for direct substitution without circuit redesign.

Enhanced Tolerance Substitutes (BZX84W-B3V0F, BZX84W-B3V0X): Both B-series variants provide tighter voltage tolerance (±2%) compared to the C-series (±5%). These parts maintain all other electrical parameters and mechanical compatibility. Selection of B-series parts results in improved voltage regulation accuracy and reduced voltage variation across production batches. Both F and X packaging variants are electrically equivalent.

Compliance and Regulatory Status: All substitute parts carry identical regulatory certifications: ROHS3 compliance, REACH unaffected status, EAR99 ECCN classification, and HTSUS code 8541.10.0050. Moisture sensitivity level remains at MSL 1 (Unlimited) across all variants, indicating no special storage or handling requirements.

Availability Consideration: Current inventory levels show BZX84W-B3V0X at 1040 pieces, BZX84W-C3V0X at 942 pieces, and BZX84W-B3V0F at 940 pieces, compared to 674 pieces of the primary part BZX84W-C3V0F.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B3V0F replace BZX84W-C3V0F in my circuit?

A: Yes. The BZX84W-B3V0F is electrically compatible. Both parts share identical nominal Zener voltage (3 V), maximum power rating (275 mW), impedance, leakage current, and forward voltage specifications. The B-series part features tighter tolerance (±2% versus ±5%), which improves voltage regulation accuracy. Both are surface mount SOT-323 packages and are mechanically interchangeable.

Q: What is the difference between the F and X packaging designations?

A: The F and X suffixes indicate different packaging formats within Tape & Reel delivery. Both formats contain identical electrical components and meet the same performance specifications. Selection between F and X variants is based on assembly equipment compatibility and supply chain requirements, not electrical performance.

Q: Are the B-series parts (±2% tolerance) always preferable to C-series parts (±5% tolerance)?

A: B-series parts provide tighter voltage tolerance, resulting in more precise voltage regulation. However, selection depends on circuit requirements. If the application tolerates ±5% voltage variation, C-series parts are suitable. If tighter voltage control is required, B-series parts are appropriate. Both meet all other electrical and mechanical specifications identically.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All parts in this substitution group, including BZX84W-C3V0F, BZX84W-B3V0F, BZX84W-B3V0X, and BZX84W-C3V0X, carry Moisture Sensitivity Level 1 (Unlimited). This indicates no special moisture control or baking procedures are required during storage or assembly.

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

A: No. All substitute parts maintain identical compliance status: ROHS3 compliant, REACH unaffected, EAR99 ECCN classification, and HTSUS code 8541.10.0050. Regulatory and environmental requirements are equivalent across all variants.

Q: Can I use BZX84W-C3V0X as a substitute for BZX84W-C3V0F?

A: Yes. These parts are electrically and mechanically identical, differing only in packaging format (F versus X designation). Both operate at 3 V nominal Zener voltage with ±5% tolerance, 275 mW power rating, and SOT-323 surface mount package. Selection between them is based on assembly process compatibility.
