Substitute Part Grouping Explanation

Substitute parts for the BZX384-B62F are identified within the BZX384 series based on matching electrical specifications and mechanical compatibility. The substitution criteria are:

Zener Voltage (Nom): 62 V (identical)
Tolerance: ±2% (identical)
Power Rating: 300 mW (identical)
Impedance (Max): 215 Ohms (identical)
Reverse Leakage Current: 50 nA @ 43.4 V (identical)
Forward Voltage: 1.1 V @ 100 mA (identical)
Operating Temperature Range: -65°C to 150°C (identical)
Package / Case: SC-76, SOD-323 (identical)
Mounting Type: Surface Mount (identical)
Compliance: ROHS3 Compliant, REACH Unaffected (identical)

Substitute parts differ only in packaging format (Tape & Reel versus Cut Tape & Digi-Reel®), which does not affect electrical performance or mechanical fit in the application circuit.

Engineering Selection Recommendations

All three parts—BZX384-B62F, BZX384-B62,115, and BZX384-B62Z—are electrically and mechanically equivalent for circuit applications requiring a 62 V Zener diode with 300 mW power rating in SOD-323 package format. Selection between these parts is determined by packaging and supply chain requirements:

BZX384-B62F (Tape & Reel): Primary specification. Use when standard reel packaging is required for automated assembly processes.

BZX384-B62,115 (Cut Tape & Digi-Reel®): Functionally equivalent. Use when smaller quantities or mixed packaging formats are required. Digi-Reel® format provides flexibility for manual or semi-automated assembly.

BZX384-B62Z (Tape & Reel): Functionally equivalent. Use as alternative reel-packaged source when primary part availability is limited.

All parts maintain Active product status, ROHS3 compliance, and REACH unaffected status. No electrical performance differences exist between these substitutes.

Frequently Asked Questions (FAQ)

Q: Can BZX384-B62,115 be used as a direct replacement for BZX384-B62F in production assembly?

A: Yes. Both parts are electrically and mechanically identical. The difference is packaging format: BZX384-B62F uses standard Tape & Reel, while BZX384-B62,115 uses Cut Tape & Digi-Reel®. Compatibility depends on assembly equipment capability to handle the respective packaging format.

Q: Are there electrical performance differences between BZX384-B62F and BZX384-B62Z?

A: No. Both parts have identical electrical specifications: 62 V nominal Zener voltage, ±2% tolerance, 300 mW power rating, 215 Ohms maximum impedance, and identical temperature operating range. Both use SOD-323 package. The only difference is inventory availability.

Q: What does the packaging designation "Digi-Reel®" mean for BZX384-B62,115?

A: Digi-Reel® is a packaging format that combines cut tape with reel capability. It provides flexibility for both manual component selection and automated reel-fed assembly processes. Electrical and mechanical specifications remain unchanged.

Q: Can these Zener diodes be used interchangeably in existing PCB designs?

A: Yes. All three parts use identical SOD-323 package dimensions and pin configuration. PCB footprints, solder pad layouts, and assembly processes are compatible across all three part numbers.

Q: Are all three parts compliant with current regulatory standards?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and carry Moisture Sensitivity Level 1 (unlimited shelf life). Compliance status is identical across all substitutes.

Q: What is the significance of the ±2% tolerance specification?

A: The ±2% tolerance indicates the maximum deviation of the actual Zener voltage from the nominal 62 V specification. This tolerance applies equally to all three substitute parts and determines the precision of voltage regulation in the application circuit.

Q: How does reverse leakage current affect part selection?

A: Reverse leakage current (50 nA @ 43.4 V) is identical across all three parts. This specification defines the maximum current flowing through the diode when reverse biased below the Zener voltage threshold. Identical values confirm functional equivalence.
