Key Parameters

Substitute Part Grouping Explanation

The TLP2719(E) qualifies as a substitute for the TLP550(LF1,F) based on the following alignment criteria:

Common Classification Parameters:

• Both components are optoisolators manufactured by Toshiba Semiconductor and Storage
• Both share identical Moisture Sensitivity Level (MSL 1 - Unlimited)
• Both carry the same ECCN classification (EAR99)
• Both fall under the same HTSUS commodity code (8541.49.8000)
• Both provide electrical isolation functionality

Substitution Basis: The TLP2719(E) represents an active product with enhanced isolation voltage specification (5000Vrms) and defined performance characteristics including 1MBd data rate, 10kV/µs common mode transient immunity, and open collector output configuration. These specifications establish functional equivalence for applications requiring optoisolation with the electrical parameters provided by this component family.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The TLP550(LF1,F) is classified as obsolete. The TLP2719(E) is an active product from the same manufacturer, ensuring ongoing availability, manufacturing support, and compliance with current industry standards.

Compliance & Certification: Both components share identical regulatory classifications (ECCN: EAR99, HTSUS: 8541.49.8000) and moisture sensitivity levels (MSL 1), confirming compatibility within regulated supply chains and storage environments.

Package & Mounting Compatibility: The TLP2719(E) is specified as a 6-SOIC surface mount component. Design integration requires verification that the target application accommodates this package footprint and surface mount assembly process. The TLP550(LF1,F) package specifications are not provided; therefore, physical compatibility assessment must be conducted against actual component datasheets and PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Why is the TLP2719(E) considered equivalent to the TLP550(LF1,F)?

A: Both components are optoisolators from Toshiba Semiconductor and Storage with identical regulatory classifications and moisture sensitivity levels. The TLP2719(E) is the active product offering from the same manufacturer, providing defined isolation voltage (5000Vrms) and performance specifications suitable for optoisolation applications.

Q: What are the key differences between these components?

A: The primary differences are product status (TLP550 is obsolete; TLP2719(E) is active) and specified performance parameters. The TLP2719(E) provides documented electrical characteristics including 1MBd data rate, 10kV/µs CMTI, and open collector output configuration. The TLP550(LF1,F) detailed specifications are not provided in this reference.

Q: Are there package compatibility considerations?

A: Yes. The TLP2719(E) is specified as a 6-SOIC surface mount package (0.295", 7.50mm width). The TLP550(LF1,F) package type is not specified. PCB layout, footprint, and assembly process compatibility must be verified against actual component datasheets and design requirements before implementation.

Q: Can the TLP2719(E) be used in existing designs without modification?

A: Package and pinout compatibility must be confirmed through detailed datasheet comparison. While both components share the same regulatory and moisture sensitivity classifications, physical and electrical interface differences may require PCB redesign or component placement adjustments.

Q: What supply chain advantages does the TLP2719(E) offer?

A: As an active product, the TLP2719(E) benefits from ongoing manufacturing support, current inventory availability, and compliance with contemporary industry standards. The obsolete status of the TLP550(LF1,F) limits future procurement options and technical support.
