ILQ2SM Equivalent & Substitute Parts

Part Overview

The ILQ2SM is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 16-pin surface mount device provides galvanic isolation up to 5300Vrms with a single channel configuration. The component is classified as Active product status with full RoHS3 compliance and REACH unaffected designation. Substitute parts are identified when equivalent electrical and mechanical parameters are required for design flexibility, inventory management, or supply chain continuity.

Substitute Part Grouping Explanation

Substitution of the ILQ2SM is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 5300Vrms
• Number of channels: 1
• Output type: Transistor
• Current transfer ratio range: 100% to 500% @ 10mA
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Package configuration: 16-SMD, Gull Wing
• Mounting type: Surface Mount
• Operating temperature range: -25°C ~ 100°C

Substitute parts must maintain identical specifications across all listed parameters to ensure functional and mechanical compatibility within the same application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both ILQ2SM and ILQ2XSM are Active status components with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on availability and supply chain requirements rather than electrical or mechanical differentiation. The ILQ2SM maintains 818 pieces in current inventory, while the ILQ2XSM maintains 751 pieces. Both components meet identical isolation voltage, output current, and thermal operating specifications. Component selection should prioritize availability and lead time requirements for the specific application timeline.

Frequently Asked Questions (FAQ)

Q: Can ILQ2XSM replace ILQ2SM in existing designs?

A: Yes. The ILQ2XSM is a parametric equivalent with identical electrical and mechanical specifications. Direct substitution is possible without circuit modification when all parameters match the design requirements.

Q: What determines if a part is a valid substitute for ILQ2SM?

A: Valid substitutes must maintain equivalence across isolation voltage (5300Vrms), channel count (1), output type (Transistor), current transfer ratio range (100-500% @ 10mA), maximum output voltage (70V), maximum output current (50mA), package configuration (16-SMD, Gull Wing), and operating temperature range (-25°C ~ 100°C).

Q: Are there package compatibility considerations between ILQ2SM and ILQ2XSM?

A: No. Both components use identical 16-SMD Gull Wing surface mount packaging. PCB footprints and reflow profiles are interchangeable.

Q: What compliance certifications apply to both substitute parts?

A: Both ILQ2SM and ILQ2XSM carry RoHS3 compliance and REACH unaffected status. No additional regulatory documentation is required for substitution.

Q: How do I select between ILQ2SM and ILQ2XSM?

A: Selection is based on inventory availability and supply chain lead times. Both parts are functionally and mechanially identical. Verify current stock levels with your supplier for the most current availability information.
