Substitute Part Grouping Explanation

Substitution of the TLP785(D4BL-F6,F) is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Current Transfer Ratio range: 200% to 600% @ 5mA
• Output Type: Transistor
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Operating Temperature range: -55°C ~ 110°C
• Package / Case: 4-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The substitute part TLP785(BL,F) maintains identical electrical specifications and mechanical compatibility. The difference between the main part and substitute lies in packaging format (tube versus the original specification) and inventory source, not in functional performance.

Parameter Comparison

Engineering Selection Recommendations

Both the TLP785(D4BL-F6,F) and TLP785(BL,F) are active production parts from Toshiba Semiconductor and Storage with identical electrical and mechanical specifications. Selection between these variants should be based on:
