Substitute Part Grouping Explanation

Substitution eligibility for the ILQ2-X009 is determined by the following critical parameters:

• Voltage - Isolation: 5300Vrms (mandatory match)
• Output Type: Transistor (mandatory match)
• Voltage - Output (Max): 70V (mandatory match)
• Current - Output / Channel: 50mA (mandatory match)
• Current Transfer Ratio range: 100% - 500% @ 10mA (mandatory match)
• Package / Case: 16-SMD, Gull Wing (mandatory match)
• Input Type: DC (mandatory match)

The ILQ2-X009 is a 4-channel device. Substitute parts identified include both parametric equivalents (maintaining 4-channel configuration) and manufacturer-recommended alternatives (single-channel variants). Single-channel substitutes require design modification to accommodate channel count differences but maintain electrical performance specifications.

Parameter Comparison

Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): ILQ2-X007 is a parametric equivalent to ILQ2-X009, maintaining identical electrical specifications and 4-channel configuration. Both parts are Last Time Buy status from Vishay Semiconductor Opto Division. This substitution requires no design modification and provides the most direct replacement path.

Manufacturer-Recommended Alternatives (Design Modification Required): ILQ2SM, ILQ2SMT&R, ILQ2XSM, and ILQ2XSMT&R are single-channel optoisolators from Isocom Components 2004 LTD with Active product status. These parts maintain all critical electrical parameters (5300Vrms isolation, 70V max output, 50mA per channel, transistor output) but differ in channel count and operating temperature range. Designs using these alternatives require four discrete components to replace the single 4-channel ILQ2-X009 unit. The Isocom variants offer extended availability due to Active status.

Packaging Considerations: Tube packaging (ILQ2SM, ILQ2XSM) and Tape & Reel packaging (ILQ2SMT&R, ILQ2XSMT&R) are available for Isocom alternatives. Selection depends on assembly process requirements and volume specifications.

Temperature Range Limitation: Isocom alternatives operate from -25°C to 100°C, compared to ILQ2-X009 and ILQ2-X007 range of -40°C to 100°C. Applications requiring operation below -25°C must use the Vishay variants.

All substitute parts maintain ROHS3 compliance and equivalent regulatory certifications.

Frequently Asked Questions (FAQ)

Q: Can ILQ2-X007 be used as a direct replacement for ILQ2-X009? A: Yes. ILQ2-X007 is a parametric equivalent with identical electrical specifications, channel count, and package configuration. No design modification is required.

Q: Why are the Isocom parts (ILQ2SM, ILQ2SMT&R, ILQ2XSM, ILQ2XSMT&R) listed as alternatives if they have only 1 channel? A: These parts are manufacturer-recommended alternatives that maintain all critical electrical performance parameters. However, they require design modification because four single-channel devices must be used in place of one 4-channel device. This substitution is viable for applications where PCB layout can accommodate multiple components.

Q: What is the difference between ILQ2SM and ILQ2SMT&R? A: Both are identical electrically and functionally. The difference is packaging: ILQ2SM is supplied in Tube packaging, while ILQ2SMT&R is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements and volume.

Q: Are there temperature range differences between substitutes? A: Yes. ILQ2-X009 and ILQ2-X007 operate from -40°C to 100°C. Isocom alternatives (ILQ2SM, ILQ2SMT&R, ILQ2XSM, ILQ2XSMT&R) operate from -25°C to 100°C. Applications requiring operation below -25°C must use Vishay parts.

Q: Do all substitute parts meet the same compliance standards? A: Yes. All listed parts are ROHS3 compliant and carry equivalent regulatory certifications (REACH Unaffected, ECCN EAR99, HTSUS 8541.49.8000).

Q: What is the difference between ILQ2XSM and ILQ2SM? A: Both are single-channel optoisolators from Isocom with identical electrical specifications. The designation difference reflects internal product line variations but does not affect electrical performance or substitution eligibility.

Q: Can I mix Tube and Tape & Reel packaging in the same design? A: Electrically, yes. However, assembly process standardization typically requires consistent packaging format. Consult your manufacturing partner regarding mixed packaging compatibility.
