IS623 Optoisolator Triac Output Equivalent & Substitute Parts

Part Overview

The IS623 is an optoisolator with triac output manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms in a single-channel configuration with 6-DIP through-hole packaging. The device is classified as Active status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical isolation, output type, channel count, and package format are maintained across the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS623 is determined by the following critical parameters:

• Voltage - Isolation: Must equal 5300Vrms
• Output Type: Must be Triac
• Number of Channels: Must be 1
• Package / Case: Must be 6-DIP (0.300", 7.62mm)
• Mounting Type: Must be Through Hole
• Voltage - Off State: Must equal 600 V

The IL410 manufactured by Vishay Semiconductor Opto Division meets all substitution criteria. Both devices maintain identical isolation voltage, triac output configuration, single-channel design, and 6-DIP package format. Both are Active status products with ROHS3 compliance and REACH Unaffected designation.

Parameter Comparison

Engineering Selection Recommendations

Both IS623 and IL410 are Active status products with ROHS3 compliance and REACH Unaffected designation. The IL410 provides an extended operating temperature range (-55°C to 100°C versus -40°C to 100°C) and improved static dV/dt performance (10kV/µs versus 600V/µs). Selection between these parts depends on application-specific requirements for temperature range and dV/dt tolerance. Both devices carry equivalent regulatory approvals suitable for industrial isolation applications.

Frequently Asked Questions (FAQ)

Q: Can IL410 directly replace IS623 in existing designs?

A: Yes. Both devices share identical isolation voltage (5300Vrms), triac output type, single-channel configuration, and 6-DIP package format. Pin-to-pin compatibility is maintained.

Q: What are the key differences between IS623 and IL410?

A: The IL410 features a lower LED trigger current (2mA versus 5mA), higher static dV/dt rating (10kV/µs versus 600V/µs), extended temperature range (-55°C to 100°C versus -40°C to 100°C), and includes zero-crossing circuit functionality. Forward voltage and hold current values differ slightly but remain within compatible operating ranges.

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

A: Yes. Both IS623 and IL410 provide 5300Vrms isolation voltage with 600V off-state voltage rating, meeting high-voltage isolation requirements in industrial and power control circuits.

Q: Do package dimensions differ between these parts?

A: No. Both parts use identical 6-DIP (0.300", 7.62mm) through-hole packaging, ensuring mechanical compatibility in PCB layouts.

Q: Are there compliance or certification differences?

A: Both parts are ROHS3 compliant and REACH Unaffected. IS623 carries UL and VDE approvals; IL410 carries CSA and UR approvals. Application requirements determine which certification set is necessary.
