Substitute Part Grouping Explanation

Substitute parts for the BZX84W-C8V2F are identified based on the following critical parameters that determine functional equivalence:

Matching Parameters (Required for Substitution):

Nominal Zener Voltage: 8.2 V
Maximum Power Dissipation: 275 mW
Package Type: SOT-323 (SC-70)
Mounting Type: Surface Mount
Maximum Impedance: 15 Ohms
Reverse Leakage Current: 700 nA @ 5 V
Forward Voltage: 900 mV @ 10 mA
Operating Temperature: 150°C (TJ)

Variable Parameter (Tolerance):

Voltage Tolerance: ±5% (main part) or ±2% (substitute variants)

The BZX84W series encompasses multiple tolerance grades. Parts with ±2% tolerance (B-grade) are tighter tolerance variants of the same base design and are electrically compatible with the ±5% tolerance (C-grade) main part. Packaging variants (F = Tape & Reel with full reel, X = Tape & Reel with cut reel) do not affect electrical performance.

Engineering Selection Recommendations

All substitute parts listed are active products manufactured by Nexperia USA Inc. and maintain identical electrical performance specifications with the main part BZX84W-C8V2F across all critical parameters: nominal Zener voltage, maximum power dissipation, impedance, leakage current, forward voltage, and operating temperature range.

BZX84W-B8V2F and BZX84W-B8V2X offer tighter voltage tolerance (±2%) compared to the main part (±5%). These variants are suitable for applications requiring improved voltage regulation accuracy and are fully compatible with circuits designed for the C8V2F variant.

BZX84W-C8V2X maintains identical tolerance (±5%) to the main part and differs only in packaging configuration (cut reel versus full reel). This variant is directly interchangeable for applications where reel format does not impact procurement or assembly processes.

All substitute parts carry ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and REACH unaffected status, matching the regulatory and environmental compliance profile of the main part.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B8V2F replace BZX84W-C8V2F in my circuit?

A: Yes. The BZX84W-B8V2F is electrically equivalent to the BZX84W-C8V2F. Both devices share identical nominal Zener voltage (8.2 V), maximum power dissipation (275 mW), impedance (15 Ohms), leakage current, forward voltage, and operating temperature. The B-grade variant features tighter voltage tolerance (±2% versus ±5%), which provides improved voltage regulation performance without compromising compatibility.

Q: What is the difference between BZX84W-C8V2F and BZX84W-C8V2X?

A: These parts are electrically identical. The difference lies in packaging configuration: the F suffix indicates a full reel of tape and reel packaging, while the X suffix indicates a cut reel. Both use the same SOT-323 package and are suitable for surface mount assembly. Selection between these variants depends on procurement quantity and assembly line requirements.

Q: Are all substitute parts in the same SOT-323 package?

A: Yes. All listed substitute parts use the SC-70, SOT-323 surface mount package. This ensures mechanical and electrical compatibility with PCB layouts designed for the BZX84W-C8V2F.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. All substitute parts are ROHS3 compliant, carry unlimited moisture sensitivity rating (MSL 1), and are REACH unaffected, matching the regulatory profile of the main part.

Q: Which substitute part should I select if voltage accuracy is critical?

A: The BZX84W-B8V2F or BZX84W-B8V2X variants offer ±2% voltage tolerance, providing tighter voltage regulation compared to the ±5% tolerance of the main part. These are suitable for precision voltage reference and regulation applications.

Q: Can I use these parts interchangeably in production?

A: Yes. All substitute parts are functionally equivalent across electrical specifications and package type. Interchangeability is determined by circuit requirements for voltage tolerance and procurement/assembly preferences for packaging format.
