TLP701F(TP,F) Equivalent & Substitute Parts

Part Overview

The TLP701F(TP,F) is a 600mA gate driver optical coupler manufactured by Toshiba Semiconductor and Storage, designed for high-voltage isolation applications requiring 5000Vrms isolation rating. This component integrates optical coupling technology in a 6-SDIP gull wing surface mount package, operating across a temperature range of -40°C to 100°C with output supply voltage specifications of 10V to 30V.

The TLP701F(TP,F) is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP701F(TP,F) is determined by the following critical parameters that must remain compatible:

Core Functional Parameters:

• Optical coupling technology for galvanic isolation
• Single-channel gate driver configuration
• 5000Vrms isolation voltage rating
• 600mA peak output current capability
• 10V to 30V output supply voltage range
• Surface mount technology

Performance Parameters:

• Common mode transient immunity minimum of 10kV/µs
• Propagation delay specifications not exceeding 700ns for both rising and falling edges
• Operating temperature range of -40°C to 100°C

The TLP5701(TP4,E) qualifies as a direct substitute based on these parameters. Both devices share identical isolation voltage, channel count, peak output current, output supply voltage range, and mounting technology. The substitute part demonstrates enhanced performance characteristics while maintaining functional compatibility with the original design.

Parameter Comparison

Engineering Selection Recommendations

The TLP5701(TP4,E) is the manufacturer-recommended substitute for the obsolete TLP701F(TP,F). This substitution is supported by the following engineering considerations:

Functional Compatibility: The substitute part maintains all critical functional parameters required for gate driver applications: identical isolation voltage (5000Vrms), channel configuration (1 channel), peak output current (600mA), and output supply voltage range (10V to 30V). Both devices employ optical coupling technology for galvanic isolation in surface mount packages.

Performance Enhancement: The TLP5701(TP4,E) provides improved performance specifications across multiple parameters. Common mode transient immunity increases from 10kV/µs to 20kV/µs, and propagation delay decreases from 700ns to 500ns for both rising and falling edges. Operating temperature range extends to 110°C, providing additional thermal margin.

Compliance and Certification: The substitute part holds active product status with comprehensive approval agency certifications including CQC, CSA, cUL, UL, and VDE. The original part lists TUV and UR approvals. The substitute's expanded certification portfolio supports broader application requirements.

Package Considerations: Both devices utilize 6-SOIC surface mount packages. The substitute package width increases from 6.80mm to 7.50mm. PCB layout verification is required to confirm footprint compatibility within existing designs, though both packages remain within the 6-SOIC family standard.

Supply Availability: The substitute part is currently in active production with documented inventory availability, addressing the supply discontinuation of the obsolete original part.

Frequently Asked Questions (FAQ)

Q: Can the TLP5701(TP4,E) directly replace the TLP701F(TP,F) in existing designs?

A: The TLP5701(TP4,E) is functionally compatible as a direct substitute for the TLP701F(TP,F) based on identical isolation voltage, channel count, peak output current, and output supply voltage specifications. PCB layout verification is required due to package width differences (6.80mm versus 7.50mm), though both are 6-SOIC packages.

Q: What are the key differences between these two parts?

A: The substitute part provides enhanced performance with improved common mode transient immunity (20kV/µs versus 10kV/µs), faster propagation delay (500ns versus 700ns), and extended operating temperature range (-40°C to 110°C versus -40°C to 100°C). The substitute is in active production status, whereas the original is obsolete.

Q: Are there any electrical parameter mismatches that would prevent substitution?

A: No electrical parameter mismatches exist that would prevent substitution. All critical functional parameters—isolation voltage, channel configuration, peak output current, and output supply voltage—are identical between the two parts.

Q: What packaging considerations apply to this substitution?

A: Both parts use 6-SOIC surface mount packages. The substitute package width is 7.50mm compared to 6.80mm for the original. Designers must verify that existing PCB layouts accommodate the slightly wider package footprint. Both packages are compatible with standard surface mount assembly processes.

Q: Does the substitute part require design re-qualification?

A: The substitute part maintains functional compatibility with identical core specifications. However, design verification should confirm PCB layout compatibility due to package width differences and validate performance improvements in the specific application context.

Q: What is the moisture sensitivity level of the substitute part?

A: The TLP5701(TP4,E) has a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
