Substitute Part Grouping Explanation

Substitute parts for the BZX84W-C62-QF are qualified based on the following criteria:

Electrical Equivalence Requirements:

• Nominal Zener voltage: 62 V (identical across all variants)
• Maximum power dissipation: 275 mW (identical across all variants)
• Maximum impedance: 215 Ohms (identical across all variants)
• Reverse leakage current: 50 nA @ 43.4 V (identical across all variants)
• Forward voltage: 900 mV @ 10 mA (identical across all variants)
• Operating temperature range: 150°C (TJ) (identical across all variants)

Mechanical Compatibility Requirements:

• Package type: SC-70, SOT-323 (identical across all variants)
• Mounting type: Surface Mount (identical across all variants)
• Supplier device package: SOT-323 (identical across all variants)

Tolerance Variation: The primary distinction among substitute parts is the Zener voltage tolerance specification. The BZX84W-C62-QF operates at ±6.45% tolerance, while substitute variants offer tighter tolerance specifications (±2% and ±5%). All tolerance grades remain within the same base product series (BZX84W) and maintain identical electrical performance parameters outside of tolerance classification.

Compliance & Status: All substitute parts maintain Active product status, RoHS3 compliance, and REACH Unaffected designation, ensuring regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

All three Zener diode variants—BZX84W-C62-QF, BZX84W-B62X, and BZX84W-C62X—are functionally equivalent for applications requiring a 62 V, 275 mW surface mount Zener diode in SOT-323 packaging. Selection between these parts is determined by tolerance requirements and application-specific voltage regulation precision.

BZX84W-C62-QF (±6.45% Tolerance): Suitable for general-purpose voltage regulation applications where standard tolerance specifications are acceptable. Maintains automotive-grade qualification with AEC-Q101 certification.

BZX84W-B62X (±2% Tolerance): Appropriate for precision voltage regulation circuits requiring tighter Zener voltage control. The ±2% tolerance specification provides enhanced voltage stability compared to the standard tolerance variant.

BZX84W-C62X (±5% Tolerance): Offers intermediate tolerance performance between standard and precision grades. Suitable for applications requiring improved voltage accuracy without the cost premium of ±2% tolerance specifications.

All parts maintain identical electrical performance parameters, mechanical compatibility, regulatory compliance status, and Active product designation. Selection should be based on circuit tolerance requirements and design specifications.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B62X and BZX84W-C62X be used interchangeably with BZX84W-C62-QF?

A: Yes. All three parts are electrically and mechanically equivalent. The primary difference is Zener voltage tolerance. BZX84W-B62X provides ±2% tolerance, BZX84W-C62X provides ±5% tolerance, and BZX84W-C62-QF provides ±6.45% tolerance. Selection depends on the circuit's tolerance requirements for the 62 V Zener voltage specification.

Q: Are there package compatibility differences between these Zener diodes?

A: No. All three parts use identical SC-70 / SOT-323 surface mount packaging and are compatible with the same PCB footprints and assembly processes.

Q: Do these substitute parts maintain automotive qualification?

A: The BZX84W-C62-QF is specified with AEC-Q101 automotive qualification. The substitute parts BZX84W-B62X and BZX84W-C62X are listed as Active products from Nexperia USA Inc. with identical electrical specifications and RoHS3 compliance. Automotive qualification status for substitute parts should be confirmed against specific design requirements.

Q: What is the significance of tolerance differences in Zener diode selection?

A: Tolerance specifications define the acceptable range of Zener voltage variation from the nominal 62 V rating. Tighter tolerances (±2%) provide more precise voltage regulation, while standard tolerances (±6.45%) allow broader voltage variation. Circuit design determines whether standard or precision tolerance grades are required.

Q: Are all three parts RoHS and REACH compliant?

A: Yes. All three Zener diodes are RoHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: Can these parts be used in high-temperature applications?

A: All three parts are rated for 150°C maximum junction temperature (TJ), supporting operation in elevated temperature environments within this specification limit.
