Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TLP701(D4-TP,F) is determined by the following critical parameters:

Isolation Voltage: Both the main part and substitute must maintain 5000Vrms isolation rating to preserve electrical safety and regulatory compliance in high-voltage applications.

Number of Channels: Single-channel configuration is required to match the original design topology.

Output Current Capability: Peak output current of 600mA must be maintained to ensure gate driver functionality and load-switching performance.

Supply Voltage Range: The 10V to 30V supply voltage window must be supported by the substitute to ensure compatibility with existing power supply designs.

Operating Temperature Range: The substitute must support the -40°C to 100°C operating window or exceed it to maintain thermal performance across all application conditions.

Surface Mount Packaging: The substitute must be surface mount to maintain PCB assembly compatibility.

Optical Coupling Technology: The substitute must utilize optical isolation technology to preserve the electrical isolation mechanism.

The TLP5701(D4-TP,E) meets all these substitution criteria and is classified as an active product with enhanced performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the TLP5701(D4-TP,E) be used as a direct replacement for the TLP701(D4-TP,F)?

A: Yes. The TLP5701(D4-TP,E) meets all critical electrical and mechanical parameters required for substitution. Both components feature identical isolation voltage (5000Vrms), output current (600mA), supply voltage range (10V–30V), and surface mount packaging. The substitute provides equal or superior performance across all specified parameters.

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

A: The primary differences are product status and performance enhancements. The TLP701(D4-TP,F) is obsolete, while the TLP5701(D4-TP,E) is an active product. The substitute offers improved common mode transient immunity (20kV/µs versus 10kV/µs), faster propagation delay (500ns versus 700ns), extended operating temperature range (-40°C to 110°C versus -40°C to 100°C), and RoHS compliance.

Q: Are there package or pinout differences?

A: Both components use 6-SOIC surface mount packages. The TLP701(D4-TP,F) specifies 0.268" (6.80mm) width, while the TLP5701(D4-TP,E) specifies 0.295" (7.50mm) width. This dimensional difference is within standard SOIC package tolerance variations and does not affect PCB footprint compatibility or pinout alignment.

Q: What is the isolation voltage rating, and does it remain the same?

A: Both the TLP701(D4-TP,F) and TLP5701(D4-TP,E) maintain a 5000Vrms isolation rating. This specification is critical for high-voltage gate driver applications and is preserved in the substitute part.

Q: Does the substitute support the same operating temperature range?

A: The TLP5701(D4-TP,E) supports an extended operating temperature range of -40°C to 110°C, compared to the original -40°C to 100°C. This provides additional thermal margin and is fully compatible with applications designed for the original temperature specification.

Q: What certifications does the substitute carry?

A: The TLP5701(D4-TP,E) is RoHS compliant. The original TLP701(D4-TP,F) carries CSA, cUL, UL, and VDE approvals. Certification details for the substitute should be verified through the manufacturer's current documentation.

Q: Is the output current capability identical?

A: Yes. Both components provide 600mA peak output current and 400mA continuous output current capability, ensuring equivalent gate driver performance in switching applications.

Q: What is the common mode transient immunity specification?

A: The TLP701(D4-TP,F) specifies 10kV/µs minimum CMTI, while the TLP5701(D4-TP,E) specifies 20kV/µs. The substitute's superior CMTI rating provides enhanced noise immunity in high-speed switching environments.
