IS6005 Optoisolator Triac Output Equivalent & Substitute Parts

Part Overview

The IS6005 is an optoisolator with triac output manufactured by Isocom Components 2004 LTD. This 6-pin DIP component provides galvanic isolation up to 5000Vrms with a single triac output channel, designed for applications requiring electrical isolation in AC switching circuits. The part is currently active in production with 2200 units in stock. Substitute parts are identified when equivalent functional performance can be achieved within the allowed electrical and mechanical parameter ranges for this optoisolator category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS6005 optoisolator is determined by the following critical parameters:

• Isolation Voltage: Substitute parts must maintain isolation voltage at or above 5000Vrms to ensure equivalent safety margins in high-voltage isolation applications
• Output Type: Must be triac output to maintain functional compatibility with AC switching circuits
• Package Configuration: Must be 6-DIP (0.300", 7.62mm) for mechanical and electrical pin compatibility
• Number of Channels: Must be single channel to match circuit integration requirements
• Mounting Type: Must be through-hole to ensure PCB assembly compatibility
• Operating Temperature Range: Must encompass or exceed the -40°C ~ 110°C range for thermal compatibility
• Electrical Characteristics: LED trigger current, hold current, forward voltage, and forward current must be within acceptable operating margins for the application circuit

The IL420 optoisolator from Vishay Semiconductor Opto Division qualifies as a substitute based on these parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the IS6005 and IL420 are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

The IL420 provides enhanced electrical performance characteristics including higher isolation voltage (5300Vrms versus 5000Vrms), superior static dV/dt rating (10kV/µs versus 1kV/µs), and lower LED trigger current requirement (2mA versus 5mA). These parameters indicate improved noise immunity and reduced input drive requirements.

The IS6005 operates across a wider temperature range (-40°C ~ 110°C) compared to the IL420 (-55°C ~ 100°C). Applications requiring operation at temperatures above 100°C must use the IS6005.

Component selection should be based on specific application requirements regarding operating temperature range and the electrical performance margins needed for the circuit design.

Frequently Asked Questions (FAQ)

Q: Can the IL420 directly replace the IS6005 in all applications?

A: The IL420 is mechanically and functionally compatible as a substitute in 6-DIP through-hole applications. However, the IS6005 supports operation up to 110°C while the IL420 is rated to 100°C maximum. Applications requiring operation above 100°C must use the IS6005.

Q: What are the key differences in electrical performance between these parts?

A: The IL420 offers higher isolation voltage (5300Vrms), superior dV/dt capability (10kV/µs), and lower LED trigger current (2mA). The IS6005 has a lower hold current requirement (200µA versus 500µA) and supports higher operating temperatures.

Q: Are both parts suitable for high-voltage isolation applications?

A: Both parts exceed 5000Vrms isolation voltage requirements. The IL420 provides additional margin with 5300Vrms isolation rating. Both are suitable for high-voltage isolation applications within their respective temperature operating ranges.

Q: Do these parts have the same pin configuration?

A: Both parts use the 6-DIP (0.300", 7.62mm) package with identical pin spacing and mounting requirements for through-hole PCB assembly.

Q: What compliance certifications apply to these optoisolators?

A: Both parts are ROHS3 compliant and REACH unaffected. The IL420 carries additional approvals from CQC, CSA, cUR, and UR agencies.
