Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N5232 is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Zener voltage rating: 5.6 V nominal
• Power dissipation capability: 500 mW minimum
• Package type: DO-35 axial through-hole configuration
• Impedance (Zzt): 11 Ohms maximum
• Reverse leakage current: 5 µA @ 3 V maximum
• Forward voltage: 1.1 V @ 200 mA maximum

The 1N5232B TR PBFREE, manufactured by Central Semiconductor Corp, meets all electrical and mechanical parameters of the original 1N5232. This substitute maintains identical zener voltage, power rating, impedance, leakage characteristics, and forward voltage specifications. The substitute is available in active production status with RoHS3 compliance and lead-free construction, providing improved supply availability compared to the obsolete original part.

Parameter Comparison

Engineering Selection Recommendations

The 1N5232B TR PBFREE is the direct functional equivalent for the obsolete 1N5232. Selection of this substitute is based on the following engineering factors:

Electrical Equivalence: All critical electrical parameters match the original specification, including zener voltage, power dissipation, impedance, leakage current, and forward voltage characteristics.

Product Status: The substitute is in active production, ensuring long-term availability and supply chain continuity. The original 1N5232 is obsolete, making the substitute the appropriate choice for new designs and ongoing production requirements.

Compliance and Standards: The 1N5232B TR PBFREE carries RoHS3 compliance and lead-free construction, meeting current environmental and regulatory requirements. Both parts maintain REACH Unaffected status and identical moisture sensitivity ratings.

Package Compatibility: Both parts utilize identical DO-35 axial through-hole packaging, ensuring mechanical and electrical compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1N5232B TR PBFREE be used as a direct replacement for the 1N5232?

A: Yes. The 1N5232B TR PBFREE is electrically and mechanically equivalent to the 1N5232. All critical parameters including zener voltage (5.6 V), power rating (500 mW), impedance (11 Ohms), and package type (DO-35 axial) are identical. The substitute is available in active production status.

Q: What is the difference between the tolerance specifications?

A: The original 1N5232 does not specify a tolerance value in the provided data. The 1N5232B TR PBFREE specifies ±5% tolerance on the zener voltage. This tolerance specification does not affect functional equivalence and is standard for zener diodes in this category.

Q: Are there packaging differences between the original and substitute?

A: Both parts use DO-35 axial through-hole packaging. The substitute is supplied in Cut Tape (CT) format, while the original packaging format is not specified. Both are compatible with standard through-hole assembly processes.

Q: Does the lead-free construction of the substitute affect performance?

A: No. The 1N5232B TR PBFREE maintains all electrical characteristics of the original part. Lead-free construction is a material composition change that does not alter the functional performance of the zener diode in circuit applications.

Q: What is the operating temperature range for the substitute?

A: The 1N5232B TR PBFREE operates from -65°C to 200°C. The original 1N5232 specifies a maximum operating temperature of 200°C. The substitute provides an extended lower temperature limit, ensuring operation across a wider temperature range.

Q: Are both parts RoHS compliant?

A: The 1N5232B TR PBFREE is RoHS3 compliant. The original 1N5232 RoHS status is not specified in the provided data. Both parts maintain REACH Unaffected status.
