Substitute Part Grouping Explanation

Substitute parts for the TLP785 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Isolation voltage: 5000Vrms minimum
• Number of channels: 1 channel configuration
• Output type: Transistor output
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Current transfer ratio range: 50% to 600% @ 5mA
• Operating temperature range: -55°C ~ 110°C minimum
• Package type: 4-DIP (0.300", 7.62mm)
• Mounting type: Through Hole

The TLP785(F) variant meets all specified parameters and qualifies as a parametric equivalent. Packaging differences (Tube vs. standard) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the TLP785 and TLP785(F) are Active products from Toshiba Semiconductor and Storage with identical electrical specifications and mechanical compatibility. Selection between these parts is based on packaging and supply requirements:

• TLP785: Standard packaging configuration with 39,200 units in inventory
• TLP785(F): Tube packaging with 2,332 units in inventory

The TLP785(F) carries RoHS3 compliance and REACH Unaffected status, providing additional regulatory documentation for applications requiring these certifications. Both parts share identical isolation voltage, current transfer ratios, output characteristics, and operating temperature ranges, ensuring direct functional interchangeability in circuit applications.

Frequently Asked Questions (FAQ)

Q: Can TLP785(F) replace TLP785 in existing designs? A: Yes. The TLP785(F) is a parametric equivalent with identical electrical and mechanical specifications. The primary difference is packaging format (Tube vs. standard), which does not affect circuit performance or PCB mounting compatibility.

Q: What determines if a part qualifies as a substitute for TLP785? A: Substitute qualification requires matching all critical parameters: 5000Vrms isolation voltage, 1-channel configuration, transistor output type, 80V maximum output voltage, 50mA maximum output current, 50-600% current transfer ratio range, -55°C to 110°C operating temperature, and 4-DIP through-hole package format.

Q: Are there differences in compliance certifications between TLP785 and TLP785(F)? A: The TLP785(F) explicitly lists RoHS3 compliance and REACH Unaffected status. Both parts carry EAR99 export classification and MSL Level 1 (Unlimited) moisture sensitivity rating.

Q: Does packaging format affect electrical performance? A: No. Tube packaging (TLP785(F)) and standard packaging (TLP785) contain identical die and internal circuitry. Packaging differences relate only to supply chain logistics and inventory management.

Q: What is the current transfer ratio specification and its significance? A: Current transfer ratio ranges from 50% to 600% at 5mA input current. This parameter defines the relationship between input LED current and output transistor current, determining the isolation amplification characteristics for signal transmission across the galvanic barrier.
