TLP785(D4,F) Equivalent & Substitute Parts

Part Overview

The TLP785(D4,F) is an optoisolator with transistor output manufactured by Toshiba Semiconductor and Storage. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 4-DIP through-hole package. The device is designed for applications requiring high-voltage isolation with DC input and transistor output switching capabilities. As an active product with 754 units in stock, the TLP785(D4,F) remains available; however, alternative packaging options and inventory levels may necessitate substitute part evaluation for procurement flexibility and supply chain optimization.

Substitute Part Grouping Explanation

Substitution eligibility for the TLP785(D4,F) is determined by strict equivalence across the following critical parameters:

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

The TLP785(F) qualifies as a parametric equivalent substitute. This variant maintains identical electrical specifications and mechanical form factor while differing only in packaging configuration (Tube packaging versus the standard packaging of the main part).

Parameter Comparison

Engineering Selection Recommendations

Both the TLP785(D4,F) and TLP785(F) are active products from Toshiba Semiconductor and Storage with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

Inventory Availability: The TLP785(D4,F) has 754 units in stock, while the TLP785(F) has 2332 units in stock. For applications with higher volume requirements or extended lead time considerations, the TLP785(F) offers greater inventory depth.

Packaging Configuration: The TLP785(D4,F) uses standard packaging, while the TLP785(F) is supplied in Tube packaging. Tube packaging is suitable for automated assembly processes and high-volume production environments. Standard packaging may be preferred for manual assembly or lower-volume applications.

Compliance Status: The TLP785(F) carries explicit RoHS3 compliance and REACH unaffected certifications. Both parts are classified under ECCN EAR99 and HTSUS 8541.49.8000. For applications requiring documented compliance certifications, the TLP785(F) provides additional regulatory documentation.

Functional Equivalence: All critical electrical parameters—isolation voltage, current transfer ratio, output voltage and current ratings, timing characteristics, and operating temperature range—are identical between both parts. Direct substitution is electrically valid for any application designed for the TLP785(D4,F).

Frequently Asked Questions (FAQ)

Q: Can the TLP785(F) be used as a direct replacement for the TLP785(D4,F)?

A: Yes. The TLP785(F) is a parametric equivalent with identical electrical specifications and mechanical form factor. Both parts are 4-DIP through-hole optoisolators with 5000Vrms isolation, single-channel transistor output, and matching current transfer ratios, output voltage/current ratings, and operating temperature ranges. The only difference is packaging configuration (Tube versus standard).

Q: What is the difference between the TLP785(D4,F) and TLP785(F) packaging?

A: The TLP785(D4,F) uses standard packaging, while the TLP785(F) is supplied in Tube packaging. Tube packaging is optimized for automated pick-and-place assembly and high-volume manufacturing. Standard packaging is suitable for manual assembly and lower-volume applications. Both maintain the same 4-DIP (0.300", 7.62mm) physical dimensions and through-hole mounting configuration.

Q: Are there any compliance differences between these parts?

A: The TLP785(F) explicitly lists RoHS3 compliance and REACH unaffected status in its documentation. Both parts are classified as EAR99 and fall under HTSUS code 8541.49.8000. For applications requiring documented regulatory compliance certifications, the TLP785(F) provides explicit compliance statements.

Q: What are the critical parameters that determine substitution eligibility?

A: Substitution eligibility is determined by equivalence in isolation voltage (5000Vrms), number of channels (1), output type (transistor), current transfer ratio range (50% to 600% @ 5mA), maximum output voltage (80V), maximum output current per channel (50mA), operating temperature range (-55°C to 110°C), package type (4-DIP), and mounting method (through-hole). Any deviation in these parameters disqualifies a part as a direct substitute.

Q: Which part should be selected for new designs?

A: Both parts are active and suitable for new designs. Selection should be based on procurement requirements: choose TLP785(F) for higher inventory availability, automated assembly processes, or when explicit RoHS3/REACH documentation is required. Choose TLP785(D4,F) for standard packaging preferences or when current inventory levels are sufficient.
