Key Parameters

Substitute Part Grouping Explanation

The TLP2719 qualifies as a substitute for the TLP550 based on the following criteria:

• Both devices are optoisolators manufactured by Toshiba Semiconductor and Storage
• Both share identical Moisture Sensitivity Level (MSL) classification of 1 (Unlimited)
• Both carry the same export control classification (ECCN: EAR99) and tariff code (HTSUS: 8541.49.8000)
• The TLP2719 maintains functional compatibility as a logic output optoisolator with enhanced isolation voltage and data rate specifications
• The TLP2719 holds active product status, ensuring long-term availability and supply chain continuity

Parameter Comparison

Engineering Selection Recommendations

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

• Compliance alignment: Both parts share identical MSL, ECCN, and HTSUS classifications, ensuring regulatory and supply chain compatibility
• Product lifecycle: The TLP2719 maintains active status, providing assured long-term availability and manufacturing support
• Manufacturer continuity: Both devices originate from Toshiba Semiconductor and Storage, maintaining design consistency and quality standards
• Functional capability: The TLP2719 delivers enhanced isolation voltage (5000Vrms) and common mode transient immunity (10kV/µs), supporting modern system requirements

Frequently Asked Questions (FAQ)

Q: Can the TLP2719 directly replace the TLP550 in existing designs?

A: The TLP2719 is functionally compatible as an optoisolator substitute. However, physical package differences must be evaluated. The TLP2719 uses 6-SOIC surface mount packaging, whereas the TLP550 package type is not specified in available documentation. PCB layout and footprint compatibility must be confirmed before implementation.

Q: What are the key differences between these parts?

A: The TLP2719 provides specified isolation voltage (5000Vrms), common mode transient immunity (10kV/µs), and data rate (1MBd) capabilities. The TLP550, being obsolete, lacks detailed electrical specifications in current documentation. The TLP2719 is surface mount only, which may differ from the original TLP550 mounting configuration.

Q: Are there compliance or export considerations?

A: Both parts carry identical export control (ECCN: EAR99) and tariff classifications (HTSUS: 8541.49.8000), eliminating compliance barriers for substitution.

Q: What is the moisture sensitivity implication?

A: Both devices are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Why is the TLP550 obsolete?

A: The TLP550 has reached end-of-life status. The TLP2719 represents Toshiba's current optoisolator offering with active production and support.
