Substitute Part Grouping Explanation

Substitution of the TLP785F(D4GRF7,F is determined by strict equivalence across the following critical parameters:

• Number of Channels: 1 channel configuration
• Voltage - Isolation: 5000Vrms minimum
• Current Transfer Ratio: 100% (Min) @ 5mA and 300% (Max) @ 5mA
• Output Type: Transistor output topology
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Package / Case: 4-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole
• Operating Temperature Range: -55°C ~ 110°C

The TLP785F(GR,F variant meets all these criteria and qualifies as a parametric equivalent. Differences in packaging format (Tube vs. standard packaging) and compliance certifications do not affect electrical or mechanical compatibility for circuit-level substitution.

Parameter Comparison
