ILQ2 Optoisolator Transistor Output Equivalent & Substitute Parts

Part Overview

The ILQ2 is a 16-pin through-hole optoisolator with transistor output, manufactured by Isocom Components 2004 LTD. This component provides galvanic isolation up to 5300Vrms with a single channel configuration, designed for DC input applications requiring high-voltage isolation and transistor-based signal detection. The ILQ2 maintains active product status with 1739 units in current inventory. Substitute parts are identified when identical electrical performance and mechanical compatibility are maintained across all critical isolation, switching, and thermal parameters.

Key Parameters

Substitute Part Grouping Explanation

The ILQ2X qualifies as a parametric equivalent substitute based on identical electrical and mechanical specifications across all critical performance criteria. Substitution is valid when the following parameters match exactly:

• Voltage isolation rating: 5300Vrms
• Current transfer ratio range: 100% to 500% @ 10mA
• Output type: Transistor
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Vce saturation: 400mV maximum
• Operating temperature range: -25°C to 100°C
• Package configuration: 16-DIP (0.300", 7.62mm)
• Mounting method: Through Hole
• Number of channels: 1
• Input type: DC

The ILQ2X differs only in packaging format (Tube versus standard packaging) and inventory availability, with no impact on electrical performance or functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ILQ2 and ILQ2X are active products with full regulatory compliance. Selection between these parts is determined by packaging and supply requirements rather than electrical performance:

• ILQ2: Standard packaging format with 1739 units in inventory
• ILQ2X: Tube packaging format with 1050 units in inventory

Both parts maintain ROHS3 compliance, REACH unaffected status, and identical electrical specifications. The choice between ILQ2 and ILQ2X depends on procurement quantity requirements, handling procedures, and assembly line compatibility with tube-fed component systems.

Frequently Asked Questions (FAQ)

Q: Can ILQ2X replace ILQ2 in existing designs? A: Yes. The ILQ2X is a direct parametric equivalent with identical electrical performance, isolation rating, output characteristics, and package dimensions. The only difference is the packaging format (Tube).

Q: What are the critical parameters that define substitution eligibility? A: Substitution is valid when isolation voltage (5300Vrms), current transfer ratio range (100-500% @ 10mA), output type (Transistor), maximum output voltage (70V), maximum output current (50mA), Vce saturation (400mV), operating temperature range (-25°C to 100°C), and package configuration (16-DIP through-hole) remain identical.

Q: Does packaging format affect electrical performance? A: No. Tube packaging (ILQ2X) and standard packaging (ILQ2) contain identical components with no impact on electrical characteristics, switching speed, isolation capability, or thermal performance.

Q: Are both parts suitable for high-voltage isolation applications? A: Yes. Both ILQ2 and ILQ2X provide 5300Vrms isolation rating and are suitable for applications requiring galvanic isolation in high-voltage environments.

Q: What is the difference in inventory availability? A: ILQ2 has 1739 units in stock, while ILQ2X has 1050 units in stock. Both maintain active product status.

Q: Are there any compliance differences between ILQ2 and ILQ2X? A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical regulatory certifications.
