BZX79-B62,113 Equivalent & Substitute Parts

Part Overview

The BZX79-B62,113 is a Zener diode manufactured by Nexperia USA Inc., rated for 62 V nominal Zener voltage with 400 mW maximum power dissipation. This through-hole component operates across a temperature range of -65°C to 200°C and is packaged in DO-204AH (DO-35) axial configuration. The part is currently in active production status with RoHS3 compliance and REACH unaffected classification. Substitute parts are identified to address inventory availability, packaging format preferences, or supply chain requirements while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BZX79-B62,113 are identified based on electrical parameter equivalence and mechanical compatibility. The primary substitution criterion is matching all critical electrical specifications: Zener voltage (62 V nominal), tolerance (±2%), maximum power rating (400 mW), impedance characteristics (215 Ohms maximum), reverse leakage current (50 nA @ 43.4 V), and forward voltage drop (900 mV @ 10 mA). The operating temperature range (-65°C to 200°C) and through-hole mounting configuration must remain consistent. Package format variations (Tape & Reel versus Bulk) do not affect electrical or mechanical substitution eligibility, as both deliver the same component in the DO-204AH axial configuration. Compliance certifications including RoHS3 and REACH status must be maintained across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

The BZX79-B62,143 is a direct parametric equivalent to the BZX79-B62,113. Both components are manufactured by NXP entities (Nexperia USA Inc. and NXP USA Inc. respectively) and share identical electrical specifications across all critical parameters. Selection between these parts is determined by packaging format requirements: the BZX79-B62,113 is supplied in Tape & Reel format suitable for automated assembly processes, while the BZX79-B62,143 is supplied in Bulk format. Both parts maintain active product status and comply with RoHS3 and REACH requirements. The choice between these substitutes depends on procurement quantity, assembly methodology, and inventory management practices rather than electrical or thermal performance considerations.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B62,143 replace BZX79-B62,113 in existing circuit designs?

A: Yes. Both parts are parametrically identical across all electrical specifications including Zener voltage (62 V), power rating (400 mW), impedance (215 Ohms maximum), and operating temperature range (-65°C to 200°C). The components are mechanically compatible in the same through-hole DO-204AH axial package configuration.

Q: What is the difference between Tape & Reel and Bulk packaging?

A: Tape & Reel packaging (BZX79-B62,113) is formatted for automated pick-and-place assembly equipment. Bulk packaging (BZX79-B62,143) consists of loose components suitable for manual assembly or alternative handling methods. The electrical and mechanical properties of the diode itself remain unchanged.

Q: Are there compliance differences between the two parts?

A: No. Both BZX79-B62,113 and BZX79-B62,143 carry identical ECCN (EAR99) and HTSUS (8541.10.0050) classifications. Both comply with RoHS3 requirements and are REACH unaffected.

Q: Does inventory availability affect substitution eligibility?

A: Inventory levels do not determine substitution eligibility. Substitution is based solely on electrical parameter matching and mechanical compatibility. The BZX79-B62,143 has higher inventory availability (35,820 pcs) compared to BZX79-B62,113 (748 pcs), which may influence procurement decisions independent of technical equivalence.

Q: Can these parts be used interchangeably in manual assembly applications?

A: Yes. Both parts are through-hole components in identical DO-204AH axial packages. Manual assembly compatibility is determined by package format, not electrical specifications. The Bulk-packaged BZX79-B62,143 may be more practical for manual assembly workflows.
