Substitute Part Grouping Explanation

Substitution of the FOD2741CV is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor (mandatory match)
• Package / Case: 8-DIP (0.300", 7.62mm) (mandatory match for through-hole mounting compatibility)
• Current Transfer Ratio: 100% - 200% @ 10mA (mandatory match)
• Voltage - Output (Max): 30V (mandatory match)
• Current - Output / Channel: 50mA (mandatory match)
• Operating Temperature: -40°C ~ 85°C (mandatory match)

The FOD2741BV meets all substitution criteria and is classified as an active product, providing continuity for applications currently using the obsolete FOD2741CV.
