Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP701HF(TP,F) is based on the following critical parameters:

Isolation Voltage: Both the main part and substitute maintain 5000Vrms isolation, meeting the same high-voltage isolation requirements.

Optical Coupling Technology: Both components use optical coupling technology, ensuring compatible signal isolation methodology.

Output Supply Voltage Range: Both operate within 10V ~ 30V, maintaining compatibility with existing power supply designs.

Operating Temperature Range: Both support -40°C ~ 125°C operation, ensuring thermal compatibility.

Surface Mount Packaging: Both use surface mount technology, compatible with standard PCB assembly processes.

Regulatory Approvals: Both hold UL, CSA, and VDE certifications, meeting industrial safety standards.

The primary difference is channel configuration: the TLP701HF(TP,F) provides 2 channels, while the TLP5771H(D4TP4,E provides 1 channel. The TLP5771H(D4TP4,E offers superior performance in propagation delay, common mode transient immunity, and output current capability, with active product status and extended availability.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The TLP701HF(TP,F) is classified as obsolete. The TLP5771H(D4TP4,E is an active product with confirmed long-term availability and higher inventory levels (2281 pcs vs. 858 pcs), making it suitable for new designs and ongoing production support.

For Regulatory Compliance: Both components hold UL, CSA, and VDE certifications. The TLP5771H(D4TP4,E additionally holds CQC certification, expanding compliance coverage for international markets.

For Channel Configuration: Applications requiring 2-channel isolation must evaluate circuit redesign or parallel implementation of single-channel devices. The TLP5771H(D4TP4,E single-channel configuration may require circuit topology modifications.

For Performance Characteristics: The TLP5771H(D4TP4,E demonstrates superior electrical performance across propagation delay (150ns vs. 700ns), common mode transient immunity (35kV/µs vs. 20kV/µs), and output current capability (1A vs. 600mA peak). These improvements provide enhanced system performance margins.

For Package Compatibility: Both components use 6-SOIC surface mount packages with slightly different body widths (6.80mm vs. 7.50mm). PCB layout verification is required to confirm footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the TLP5771H(D4TP4,E directly replace the TLP701HF(TP,F) in existing designs?

A: Direct replacement requires circuit evaluation. The primary difference is channel count: TLP701HF(TP,F) provides 2 channels while TLP5771H(D4TP4,E provides 1 channel. Applications using both channels must implement parallel devices or redesign the isolation topology. Package dimensions differ slightly (6.80mm vs. 7.50mm width), requiring PCB footprint verification.

Q: What are the key electrical advantages of the TLP5771H(D4TP4,E?

A: The TLP5771H(D4TP4,E offers three primary electrical improvements: propagation delay reduced from 700ns to 150ns, common mode transient immunity increased from 20kV/µs to 35kV/µs, and peak output current increased from 600mA to 1A. These enhancements provide faster signal transmission, improved noise immunity, and higher drive capability.

Q: Are both components suitable for the same isolation voltage applications?

A: Yes. Both components provide 5000Vrms isolation voltage and operate within the same 10V ~ 30V output supply range, making them suitable for equivalent high-voltage isolation applications.

Q: What is the impact of the package dimension difference?

A: Both use 6-SOIC surface mount packages, but the TLP5771H(D4TP4,E has a slightly wider body (7.50mm vs. 6.80mm). PCB layout must be verified to confirm the footprint accommodates the larger package width without trace or component interference.

Q: Why is the TLP5771H(D4TP4,E recommended over the obsolete TLP701HF(TP,F)?

A: The TLP5771H(D4TP4,E is an active product with higher inventory availability (2281 pcs vs. 858 pcs), ensuring long-term supply continuity. It also provides superior electrical performance and expanded regulatory certifications (CQC added), making it the preferred choice for new designs and production support.

Q: Are regulatory certifications equivalent between the two parts?

A: Both hold UL, CSA, and VDE certifications. The TLP5771H(D4TP4,E additionally holds CQC certification. For applications requiring specific regional compliance, verify that the substitute meets all required certifications for the target market.
