Substitute Part Grouping Explanation
Substitution of the TLP785F(YH-TP7,F with the TLP785(D4YH-T6,F is based on strict equivalence of the following critical parameters:
- Isolation voltage: 5000Vrms (identical)
- Number of channels: 1 (identical)
- Current transfer ratio range: 75% to 150% @ 5mA (identical)
- Output type: Transistor (identical)
- Maximum output voltage: 80V (identical)
- Maximum output current: 50mA (identical)
- Vce saturation: 400mV (identical)
- Operating temperature range: -55°C ~ 110°C (identical)
- Package type: 4-SMD, Gull Wing (identical)
- Base product number: TLP785 (identical)
Both parts maintain identical electrical performance characteristics and mechanical compatibility. The primary difference is packaging format: the main part uses standard packaging while the substitute is supplied in Tape & Reel (TR) format.
