Key Parameters

Substitute Part Grouping Explanation

Substitution of the FOD2741CSD is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 5000Vrms
• Number of channels: 1
• Output type: Transistor
• Input type: DC
• Maximum output voltage: 30V
• Maximum output current per channel: 50mA
• Current transfer ratio range: 100% to 200% @ 10mA
• Package type: 8-SMD, Gull Wing
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount

The FOD2741BSD meets all these criteria and qualifies as a direct substitute. The primary distinction between these parts is product status and packaging format availability.

Parameter Comparison

Engineering Selection Recommendations

The FOD2741BSD is the direct substitute for FOD2741CSD. Both components share identical electrical and mechanical specifications across all critical parameters. The FOD2741BSD holds active product status, ensuring ongoing manufacturer support, availability, and compliance with current regulatory standards. The FOD2741BSD carries RoHS3 compliance certification, meeting modern environmental and safety requirements.
