1N4689-TP Zener Diode Equivalent & Substitute Parts

Part Overview

The 1N4689-TP is a 5.1 V zener diode rated for 500 mW power dissipation in a DO-35 axial through-hole package. Manufactured by Micro Commercial Co, this component is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying equivalent substitute parts with matching electrical and mechanical specifications is necessary for design continuity and procurement flexibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1N4689-TP are selected based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Electrical Parameters:

• Zener voltage: 5.1 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 500 mW
• Reverse leakage current: 10 µA @ 3 V
• Forward voltage: 1.5 V @ 100 mA maximum

Mechanical Parameters:

• Package type: DO-35 axial through-hole
• Mounting configuration: Through-hole compatible

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

The 1N4689 TR PBFREE from Central Semiconductor Corp meets all specified electrical and mechanical parameters while offering active product status and tape & reel packaging availability.

Parameter Comparison

Engineering Selection Recommendations

The 1N4689 TR PBFREE from Central Semiconductor Corp is a direct electrical and mechanical equivalent to the 1N4689-TP. Both components share identical zener voltage, power rating, tolerance, and reverse leakage specifications. Both are RoHS3 compliant and REACH unaffected.

The primary distinction is product status: the 1N4689-TP is obsolete, while the 1N4689 TR PBFREE is active. This makes the substitute part suitable for new designs and ongoing production requirements. The substitute part is available in tape & reel packaging, which is standard for automated assembly processes.

For applications requiring the original bulk packaging format of the 1N4689-TP, the electrical specifications of the 1N4689 TR PBFREE remain fully compatible. The component can be used in identical circuit configurations without modification.

Frequently Asked Questions (FAQ)

Q: Can the 1N4689 TR PBFREE replace the 1N4689-TP in existing designs?

A: Yes. Both components have identical electrical specifications: 5.1 V zener voltage, ±5% tolerance, 500 mW power rating, and matching forward and reverse leakage characteristics. The DO-35 axial through-hole package is identical, allowing direct substitution in PCB layouts and circuit designs.

Q: What is the difference between the 1N4689-TP and 1N4689 TR PBFREE?

A: The primary differences are manufacturer (Micro Commercial Co versus Central Semiconductor Corp), product status (obsolete versus active), and packaging format (bulk versus tape & reel). All electrical and mechanical parameters are identical.

Q: Is the tape & reel packaging of the 1N4689 TR PBFREE compatible with through-hole assembly?

A: Yes. Tape & reel packaging is a standard distribution format for through-hole components. The individual components are identical to those supplied in bulk packaging and are compatible with both manual and automated assembly processes.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the 1N4689-TP and 1N4689 TR PBFREE are RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the 1N4689-TP listed as obsolete?

A: Obsolete status indicates that the original manufacturer (Micro Commercial Co) has discontinued production. The 1N4689 TR PBFREE from Central Semiconductor Corp provides an active alternative with identical specifications.

Q: Can I use the 1N4689 TR PBFREE in high-temperature applications?

A: The 1N4689 TR PBFREE is rated for operating temperatures from -65°C to 200°C (TJ). Verify that your specific application requirements fall within this range.
