1N710 Equivalent & Substitute Zener Diodes Reference

Part Overview

The 1N710 from Microchip Technology is a Zener diode with a nominal Zener voltage of 6.8 V, maximum power dissipation of 250 mW, ±10% voltage tolerance, and a DO-204AH, DO-35 axial lead through-hole package. It is a RoHS non-compliant part, currently active and stocked. Due to factors such as compliance requirements, power rating needs, or inventory constraints, it is sometimes necessary to identify alternative part numbers with matching electrical and mechanical parameters in the Diodes, Zener category.

Key Parameters

Substitute Part Grouping Explanation

Substitute Zener diodes are identified using strictly equivalent or better values for these parameters:

• Nominal Zener Voltage
• Tolerance
• Maximum Power Dissipation
• Impedance (Max)
• Mounting Type
• Package / Case

To qualify as a substitute, the component must match or exceed the electrical requirements and be mechanically compatible with the original package and mounting style.

Parameter Comparison

Engineering Selection Recommendations

The 1N710 is RoHS non-compliant, while the BZX79-B6V8,133 is ROHS3 Compliant. Both parts are listed as active. Selection may be based on required compliance for new designs or availability in procurement channels. Specification matching based purely on electrical and mechanical fields provided.

Frequently Asked Questions (FAQ)

Q1: What are the most important parameters when selecting a Zener diode substitute?
A1: The most important parameters are nominal Zener voltage, tolerance, maximum power rating, impedance, mounting type, and mechanical package compatibility.

Q2: Is package equivalency mandatory for substitution?
A2: Yes, substituting Zener diodes requires equivalent package and mounting to ensure mechanical and electrical compatibility in existing designs.

Q3: Can substitute diodes have tighter tolerances or higher power ratings than the original?
A3: Yes, using a substitute with a tighter tolerance or higher power rating is permitted, as long as all other matching parameters are satisfied.

Q4: How does RoHS status affect Zener diode selection?
A4: If RoHS compliance is required, selection should favor a compliant part such as BZX79-B6V8,133. If not required, non-compliant parts like 1N710 remain valid choices.

Q5: Are there differences between supplier device package descriptions such as DO-35 and ALF2?
A5: Both DO-35 and ALF2 refer to standard axial lead through-hole packages equivalent to DO-204AH, ensuring mechanical compatibility. Only package descriptions provided are considered.
