Substitute Part Grouping Explanation

The TLP2719(E) qualifies as a functional substitute based on the following alignment criteria:

Common Classification Parameters:

• Category: Optoisolators (both single-channel isolation devices)
• Manufacturer: Toshiba Semiconductor and Storage (same manufacturer ecosystem)
• Moisture Sensitivity Level: 1 (Unlimited) — identical environmental rating
• ECCN Classification: EAR99 — matching export control designation
• HTSUS Code: 8541.49.8000 — identical tariff classification
• Number of Channels: 1 (both single-channel configurations)
• Input/Output Configuration: 1 input channel, 0 secondary inputs (matched topology)

The TLP2719(E) maintains the core isolation function of the obsolete TLP550(PP,F) while providing active product status and enhanced electrical performance specifications suitable for direct substitution in isolation circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(E) is the designated substitute for the obsolete TLP550(PP,F) based on product lifecycle status and regulatory compliance alignment. Both components share identical MSL ratings and export control classifications, ensuring compatibility within existing supply chain and compliance frameworks. The TLP2719(E) maintains active product status with established manufacturing continuity, eliminating obsolescence risk associated with the TLP550(PP,F).

Selection of the TLP2719(E) is supported by matching isolation category, single-channel topology, and identical environmental/regulatory designations. The active product status of the TLP2719(E) provides assured long-term availability and technical support compared to the obsolete TLP550(PP,F).

Frequently Asked Questions (FAQ)

Q: Why is the TLP550(PP,F) being phased out? A: The TLP550(PP,F) is classified as obsolete. The TLP2719(E) represents the active product line continuation from Toshiba Semiconductor and Storage for single-channel optoisolator applications.

Q: Are the TLP550(PP,F) and TLP2719(E) pin-compatible? A: Pin compatibility is not specified in the available technical parameters. Physical package verification is required during design integration. The TLP550(PP,F) uses unspecified packaging, while the TLP2719(E) uses 6-SOIC (0.295", 7.50mm Width) surface mount configuration.

Q: What are the key isolation specifications of the TLP2719(E)? A: The TLP2719(E) provides 5000Vrms isolation voltage with 10kV/µs common mode transient immunity, supporting 1MBd data rate operation with open collector output configuration.

Q: Are both parts subject to the same export controls? A: Yes. Both the TLP550(PP,F) and TLP2719(E) carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring consistent regulatory treatment.

Q: What is the moisture sensitivity rating for these components? A: Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
