Substitute Part Grouping Explanation

Substitute parts for the BZX84W-C62F are identified based on strict electrical and mechanical parameter equivalence within the BZX84W series. The substitution criteria are:

Primary Equivalence Parameters:

• Zener voltage (Nom): 62 V
• Maximum power dissipation: 275 mW
• Package type: SOT-323 (SC-70)
• Mounting type: Surface Mount
• Impedance (Max): 215 Ohms
• Reverse leakage current: 50 nA @ 43.4 V
• Forward voltage: 900 mV @ 10 mA
• Operating temperature: 150°C (TJ)

Tolerance Variation: The BZX84W-C62F operates with ±5% Zener voltage tolerance. The substitute BZX84W-B62X offers tighter tolerance at ±2%, which remains functionally compatible as it represents a subset of the original tolerance band. The BZX84W-C62X maintains identical ±5% tolerance.

All substitute parts share the same base product number (BZX84W), manufacturer (Nexperia USA Inc.), series designation, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Parameter Comparison

Engineering Selection Recommendations

All three parts—BZX84W-C62F, BZX84W-B62X, and BZX84W-C62X—are active products from Nexperia USA Inc. with identical electrical specifications, package geometry, and compliance certifications. Selection between these parts is determined by tolerance requirements and application-specific voltage regulation precision.

BZX84W-C62F (±5% Tolerance): Suitable for applications where standard voltage tolerance of ±5% meets circuit requirements. This part maintains the widest tolerance band and is appropriate for general-purpose voltage regulation and protection circuits.

BZX84W-B62X (±2% Tolerance): Applicable when tighter voltage tolerance is required. The ±2% tolerance provides improved voltage accuracy compared to the ±5% specification, making it suitable for precision voltage reference applications. This part is functionally interchangeable with the BZX84W-C62F while offering enhanced tolerance performance.

BZX84W-C62X (±5% Tolerance): Functionally identical to the BZX84W-C62F with matching ±5% tolerance specification. This part provides equivalent performance and is interchangeable for direct replacement.

All parts carry ROHS3 compliance and REACH Unaffected status, confirming regulatory compliance for industrial and commercial applications. Moisture sensitivity level MSL 1 (Unlimited) indicates no special moisture handling requirements during manufacturing or storage.

Frequently Asked Questions (FAQ)

Q: Can BZX84W-B62X replace BZX84W-C62F in all applications?

A: Yes. The BZX84W-B62X is electrically and mechanically equivalent to the BZX84W-C62F. The ±2% tolerance of the BZX84W-B62X is a tighter specification than the ±5% tolerance of the BZX84W-C62F, meaning it operates within a narrower voltage range. This makes it suitable for all applications where the BZX84W-C62F is used, with the added benefit of improved voltage accuracy.

Q: What is the difference between BZX84W-C62F and BZX84W-C62X?

A: Both parts are identical in all electrical and mechanical parameters. The difference lies in the packaging designation: BZX84W-C62F is supplied in Tape & Reel (TR) format, while BZX84W-C62X also uses Tape & Reel packaging. Both are surface mount SOT-323 packages with ±5% tolerance and 62 V nominal Zener voltage.

Q: Are these parts compatible with existing PCB designs?

A: Yes. All three substitute parts use the identical SOT-323 (SC-70) package footprint and surface mount configuration. Direct PCB layout compatibility is maintained without design modifications.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant, REACH Unaffected, and carry EAR99 export classification. Moisture sensitivity level is MSL 1 (Unlimited), indicating no special moisture control requirements during assembly or storage.

Q: When should I select BZX84W-B62X over BZX84W-C62F?

A: Select BZX84W-B62X when circuit design requires voltage regulation accuracy within ±2% tolerance. Applications involving precision voltage references, sensitive analog circuits, or systems with tight voltage specifications benefit from the improved tolerance performance of the BZX84W-B62X.

Q: Are inventory levels a consideration for part selection?

A: Inventory availability is provided for reference: BZX84W-C62F (917 Pcs), BZX84W-B62X (942 Pcs), and BZX84W-C62X (1138 Pcs). All parts are in stock as new original components. Selection should be based on electrical and mechanical requirements rather than inventory status.
