TLP785F(D4-GR,F Optoisolator Transistor Output Equivalent & Substitute Parts

Part Overview

The TLP785F(D4-GR,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 part is currently active in production status with 1025 units available in new original stock. Alternative part numbers are necessary when the primary variant is unavailable or when specific packaging requirements differ between procurement channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP785F(D4-GR,F is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 5000Vrms
• Number of channels: 1
• Output type: Transistor
• Current transfer ratio range: 100% to 300% @ 5mA
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Package type: 4-DIP through-hole configuration
• Switching characteristics: Turn on/off time 3µs, rise/fall time 2µs/3µs
• Operating temperature range: -55°C to 110°C

The TLP785F(GR,F variant meets all parametric requirements for direct substitution. The primary difference is packaging format (tube versus the original packaging specification), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the TLP785F(D4-GR,F and TLP785F(GR,F are active production parts from Toshiba Semiconductor and Storage. Selection between these variants is based on procurement and inventory requirements rather than electrical performance differences.

The TLP785F(D4-GR,F is suitable for applications requiring the original packaging specification with 1025 units currently in stock. The TLP785F(GR,F in tube packaging is suitable for high-volume procurement with 1044 units available and carries ROHS3 compliance certification. Both parts are classified under ECCN EAR99 and HTSUS 8541.49.8000.

Frequently Asked Questions (FAQ)

Q: Can TLP785F(GR,F replace TLP785F(D4-GR,F in existing designs?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. The difference is packaging format (tube versus original specification). Pin configuration, package dimensions (4-DIP 0.400" / 10.16mm), and mounting type (through-hole) are identical.

Q: What determines substitution eligibility for TLP785 optoisolators?

A: Substitution is valid when the alternative part maintains identical specifications for isolation voltage (5000Vrms), channel count (1), output type (transistor), current transfer ratio range (100-300% @ 5mA), maximum output voltage (80V), maximum output current (50mA), switching times (3µs on/off, 2µs/3µs rise/fall), and operating temperature range (-55°C to 110°C).

Q: Are there compliance differences between the two variants?

A: The TLP785F(GR,F carries explicit ROHS3 compliance and REACH unaffected status certifications. Both parts are classified as ECCN EAR99 and share the same HTSUS code. Verify compliance requirements for your specific application and region.

Q: What is the significance of the packaging difference?

A: Tube packaging affects handling, storage, and automated assembly processes but does not alter electrical performance or pin compatibility. Selection depends on your procurement workflow and assembly equipment specifications.
