Substitute Part Grouping Explanation

The TLP2719(E) qualifies as a substitute for the TLP550 based on the following critical parameters:

• Category Match: Both components are optoisolators within the same product family
• Manufacturer Consistency: Both manufactured by Toshiba Semiconductor and Storage
• Regulatory Compliance: Identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)
• Single Channel Configuration: Both provide 1-channel optoisolation
• Product Status Advantage: TLP2719(E) is Active, providing long-term availability

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(E) is the designated substitute for the obsolete TLP550. Selection is based on:

• Product Status: TLP2719(E) maintains Active status, ensuring continued manufacturing and supply chain availability
• Regulatory Alignment: Both components share identical ECCN and HTSUS classifications, maintaining compliance requirements
• Manufacturer Continuity: Both components originate from Toshiba Semiconductor and Storage, ensuring design consistency and technical support
• Moisture Sensitivity Equivalence: Identical MSL 1 rating eliminates moisture-related handling and storage concerns

Frequently Asked Questions (FAQ)

Q: Why is the TLP550 being replaced? A: The TLP550 is classified as obsolete. The TLP2719(E) is an active product from the same manufacturer, providing equivalent functionality with assured long-term availability.

Q: Are the TLP550 and TLP2719(E) pin-compatible? A: Pin compatibility is not specified in the available technical parameters. Physical package verification is required during design integration.

Q: What is the isolation voltage rating for substitution purposes? A: The TLP2719(E) provides 5000Vrms isolation voltage. Confirmation that this meets system requirements is necessary before implementation.

Q: Can the TLP2719(E) operate across the same temperature range as the TLP550? A: The TLP2719(E) operates from -40°C to 100°C. System temperature requirements must be verified against this specification.

Q: What packaging format does the TLP2719(E) use? A: The TLP2719(E) is supplied in 6-SOIC (0.295", 7.50mm Width) surface mount package format, differing from the TLP550 package type which is not specified in available data.
