Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TLP371(LF1,F) is determined by alignment across the following critical parameters:

• Manufacturer Consistency: Toshiba Semiconductor and Storage maintains product line continuity through the TLP627 series
• Component Category: All substitutes remain classified as optoisolators
• Isolation Voltage: Minimum 5000Vrms isolation rating required for equivalent functionality
• Output Configuration: Single-channel optoisolator output architecture
• Compliance & Certification: ECCN EAR99 and HTSUS 8541.49.8000 classification maintained across all alternatives
• Moisture Sensitivity: MSL 1 (Unlimited) rating preserved for storage and handling compatibility

The TLP627M(LF1,E) series represents the primary active substitute line, offering enhanced performance characteristics while maintaining backward compatibility with the isolation and channel requirements of the original TLP371 design.

Parameter Comparison

Engineering Selection Recommendations

The TLP371(LF1,F) is classified as obsolete, necessitating transition to active product lines for new procurement and long-term system support. The TLP627M(LF1,E) is the designated substitute, maintaining Toshiba manufacturer continuity and optoisolator category classification. Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) compliance codes, ensuring regulatory alignment for export and tariff purposes.

The TLP627M(LF1,E) provides enhanced specifications including 5000Vrms isolation voltage, Darlington output configuration, and surface-mount packaging in 4-SMD format. The active product status of the TLP627M series ensures ongoing availability, technical support, and supply chain reliability compared to the obsolete TLP371 line.

Selection of the TLP627M(LF1,E) substitute is supported by matching MSL 1 (Unlimited) moisture sensitivity classification, enabling direct replacement in existing assembly and storage protocols without additional environmental controls.

Frequently Asked Questions (FAQ)

Q: Why is the TLP371(LF1,F) being discontinued? A: The TLP371(LF1,F) is classified as obsolete by Toshiba Semiconductor and Storage. The TLP627M series represents the active product line continuation for single-channel optoisolator applications.

Q: What are the key differences between TLP371(LF1,F) and TLP627M(LF1,E)? A: The TLP627M(LF1,E) features a Darlington output configuration, 5000Vrms isolation voltage rating, 150mA output current capability, and surface-mount 4-SMD packaging. Both maintain identical compliance classifications and MSL 1 moisture sensitivity ratings.

Q: Are there packaging considerations when substituting to TLP627M(LF1,E)? A: The TLP627M(LF1,E) uses surface-mount 4-SMD Gull Wing packaging. Verify that your PCB assembly process and footprint design accommodate this package type before implementation.

Q: Do both components share the same regulatory compliance codes? A: Yes. Both the TLP371(LF1,F) and TLP627M(LF1,E) are classified under ECCN EAR99 and HTSUS 8541.49.8000, ensuring consistent export and tariff treatment.

Q: Is the TLP627M(LF1,E) available in alternative packaging options? A: The TLP627 base product number includes variants such as TLP627M(LF5,E), TLP627MF(LF4,E), TLP627MF(E), and TLP627M(D4-LF5,E), offering different packaging and lead configurations within the same product family.

Q: What is the moisture sensitivity level for both components? A: Both the TLP371(LF1,F) and TLP627M(LF1,E) carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.
