Substitute Part Grouping Explanation

Substitute parts for the BZX79-B30,113 are qualified based on electrical parameter equivalence and mechanical compatibility. The substitution criteria are strictly defined by the following parameters:

• Voltage - Zener (Nominal): 30 V
• Tolerance: ±2%
• Power - Maximum: 400 mW
• Impedance (Maximum): 80 Ohms
• Current - Reverse Leakage @ Vr: 50 nA @ 21 V
• Voltage - Forward (Maximum) @ If: 900 mV @ 10 mA
• Operating Temperature Range: -65°C to 200°C
• Mounting Type: Through Hole
• Package / Case: DO-204AH, DO-35, Axial
• Supplier Device Package: ALF2

Parts meeting all these electrical and mechanical specifications are classified as parametric equivalents. Variations in packaging format (Cut Tape versus Bulk) and inventory levels do not affect functional substitutability. All substitute parts maintain identical performance characteristics and are suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—BZX79-B30,113, BZX79-B30,133, and BZX79-B30,143—are active production components with identical electrical and mechanical specifications. Selection between these parts is determined by packaging and supply requirements rather than functional performance.

This part is suitable for high-volume applications where bulk packaging is acceptable. Compliance certifications are not specified in the provided data.

BZX79-B30,143 (Nexperia USA Inc., Cut Tape packaging) offers equivalent performance with ROHS3 compliance and REACH Unaffected status. Inventory is 6,057 pieces. This part is interchangeable with BZX79-B30,113 for applications requiring tape-and-reel format from the same manufacturer.

All parts maintain identical performance across the full operating temperature range and are suitable for direct circuit substitution.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B30,133 replace BZX79-B30,113 in production assemblies?

A: Yes. Both parts have identical electrical parameters (30 V nominal, 400 mW, ±2% tolerance, 80 Ohms impedance) and mechanical specifications (DO-204AH/DO-35 axial through-hole). The primary difference is packaging format (Bulk versus Cut Tape). Compliance certifications for BZX79-B30,133 are not specified in the provided data; verify ROHS and REACH requirements for your application.

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

A: Cut Tape (CT) packaging provides components on continuous tape suitable for automated pick-and-place equipment. Bulk packaging supplies loose components. Both formats contain identical components with the same electrical and mechanical specifications. Selection depends on assembly process requirements and handling procedures.

Q: Are all three parts suitable for the same circuit applications?

A: Yes. BZX79-B30,113, BZX79-B30,133, and BZX79-B30,143 are parametric equivalents with identical zener voltage (30 V), power rating (400 mW), impedance (80 Ohms), and operating temperature range (-65°C to 200°C). Direct substitution is supported for all circuit applications.

Q: What compliance certifications apply to each part?

A: BZX79-B30,113 and BZX79-B30,143 are explicitly documented as ROHS3 Compliant and REACH Unaffected. BZX79-B30,133 compliance certifications are not specified in the provided data. All three parts carry ECCN EAR99 and HTSUS 8541.10.0050 classifications.

Q: Which part should be selected for new designs?

A: Selection is based on supply chain and assembly requirements. BZX79-B30,113 and BZX79-B30,143 (both Nexperia USA Inc., Cut Tape) are recommended for applications requiring documented ROHS3 and REACH compliance. BZX79-B30,133 (NXP USA Inc., Bulk) is suitable for high-volume production where bulk packaging is acceptable and compliance requirements are verified separately.

Q: Is the ALF2 supplier device package identical across all three parts?

A: Yes. All three parts use the ALF2 supplier device package designation, confirming mechanical and electrical equivalence. The package corresponds to the DO-204AH/DO-35 axial through-hole configuration.
