Substitute Part Grouping Explanation

The ILQ1XSM qualifies as a parametric equivalent to the ILQ1SM based on the following criteria:

Electrical Parameters Match:

• Voltage isolation rating: 5300Vrms (identical)
• Current transfer ratio range: 20% to 300% @ 10mA (identical)
• Output voltage maximum: 50V (identical)
• Output current per channel: 50mA (identical)
• Vce saturation: 400mV maximum (identical)
• Operating temperature range: -25°C ~ 100°C (identical)

Mechanical Parameters Match:

• Package type: 16-SMD, Gull Wing (identical)
• Mounting type: Surface Mount (identical)
• Number of channels: 1 (identical)

Compliance Parameters Match:

• RoHS Status: ROHS3 Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)
• REACH Status: REACH Unaffected (identical)

The ILQ1XSM maintains full electrical and mechanical compatibility with the ILQ1SM, allowing direct substitution in applications where the specified parameters are the selection criteria.
