Substitute Part Grouping Explanation

Substitute parts for the BZX79-B5V6,113 are classified into two categories based on electrical and mechanical parameter alignment:

Parametric Equivalents maintain identical or functionally equivalent electrical specifications across all critical parameters: nominal zener voltage (5.6 V), tolerance (±2%), maximum power dissipation (400 mW), impedance (40 Ohms maximum), reverse leakage current (1 µA @ 2 V), forward voltage (900 mV @ 10 mA), operating temperature range (-65°C to 200°C), and through-hole axial package configuration. These parts differ only in packaging format (Bulk versus Cut Tape) and manufacturer designation codes.

Similar Equivalents share the same nominal zener voltage (5.6 V) and through-hole axial package type but exhibit variations in tolerance (±5% versus ±2%), maximum power dissipation (500 mW versus 400 mW), reverse leakage current (5 µA @ 3 V versus 1 µA @ 2 V), and forward voltage characteristics (1.1 V @ 200 mA versus 900 mV @ 10 mA). These parts are suitable for applications where the relaxed tolerance and increased power rating do not conflict with circuit design constraints.

Parameter Comparison

Engineering Selection Recommendations

BZX79-B5V6,133 and BZX79-B5V6,143 are direct parametric equivalents to the BZX79-B5V6,113. Both parts maintain identical electrical specifications across all critical parameters: 5.6 V nominal zener voltage, ±2% tolerance, 400 mW maximum power dissipation, 40 Ohms maximum impedance, 1 µA reverse leakage current at 2 V, and 900 mV forward voltage at 10 mA. The primary distinction is packaging format: BZX79-B5V6,133 and BZX79-B5V6,143 are supplied in Bulk packaging, whereas BZX79-B5V6,113 is supplied in Cut Tape. Both substitute parts are Active products with REACH Unaffected status. Selection between these three parts depends solely on packaging requirements and inventory availability.

1N5232B-TAP is classified as a similar equivalent suitable for applications where increased power dissipation capability and relaxed tolerance specifications are acceptable. This Vishay part maintains the 5.6 V nominal zener voltage and through-hole axial package configuration but differs in tolerance (±5%), maximum power rating (500 mW), reverse leakage current (5 µA @ 3 V), and forward voltage (1.1 V @ 200 mA). The 1N5232B-TAP is an Active product with ROHS3 compliance and REACH Unaffected status. This part is suitable for circuits where the ±2% tolerance requirement is not mandatory and where the higher power dissipation capability provides design margin.

Frequently Asked Questions (FAQ)

Q: Can BZX79-B5V6,133 or BZX79-B5V6,143 be used as direct replacements for BZX79-B5V6,113?

A: Yes. BZX79-B5V6,133 and BZX79-B5V6,143 are parametric equivalents with identical electrical specifications. All critical parameters—nominal zener voltage, tolerance, power dissipation, impedance, reverse leakage current, forward voltage, and operating temperature range—are equivalent. The only difference is packaging format (Bulk versus Cut Tape). Direct substitution is valid from an electrical and mechanical standpoint.

Q: What are the limitations of using 1N5232B-TAP as a substitute?

A: The 1N5232B-TAP differs in three key parameters: tolerance (±5% versus ±2%), maximum power dissipation (500 mW versus 400 mW), and reverse leakage current (5 µA @ 3 V versus 1 µA @ 2 V). Applications requiring strict ±2% voltage tolerance or low reverse leakage characteristics must verify circuit compatibility before substitution. The increased power rating does not present a limitation; it provides additional design margin.

Q: Are all substitute parts RoHS compliant?

A: BZX79-B5V6,113 and 1N5232B-TAP are explicitly ROHS3 compliant. RoHS status for BZX79-B5V6,133 and BZX79-B5V6,143 is not specified in the provided data. All four parts maintain REACH Unaffected status.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Cut Tape versus Bulk) does not affect electrical performance. The distinction is logistical: Cut Tape packaging is suitable for automated assembly processes, while Bulk packaging is used for manual assembly or alternative distribution methods. Electrical specifications remain identical regardless of packaging format.

Q: What is the operating temperature difference between the main part and 1N5232B-TAP?

A: BZX79-B5V6,113 operates across -65°C to 200°C, while 1N5232B-TAP operates up to 175°C. Applications requiring operation above 175°C must use BZX79-B5V6,113, BZX79-B5V6,133, or BZX79-B5V6,143.

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

A: Yes, provided the PCB design accommodates the DO-204AH (DO-35) axial through-hole package. All four parts use identical package geometry and pin configuration. No PCB layout modifications are required for substitution.
