Substitute Part Grouping Explanation

Substitute parts for the ISD202G are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria are:

• Voltage isolation rating: 5300Vrms
• Number of channels: 1
• Current transfer ratio range: 125% to 250% @ 10mA
• Output type: Transistor
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Maximum Vce saturation: 400mV
• Operating temperature range: -25°C to 100°C
• Package type: 8-DIP (0.400", 10.16mm)
• Mounting type: Through Hole
• RoHS compliance: ROHS3 Compliant

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison
