• Isolation Voltage: TLP785 provides 5000Vrms isolation, meeting or exceeding typical application requirements for optoisolator circuits
• Output Configuration: TLP785 features transistor output with single channel architecture, compatible with standard optoisolator circuit topologies
• Compliance Standards: Both components carry EAR99 ECCN classification and identical HTSUS coding (8541.49.8000)
• Product Status: TLP785 maintains active product status, ensuring long-term availability and supply reliability

Parameter Comparison

Engineering Selection Recommendations

The TLP785(GR-LF6,F) is the appropriate substitute for the obsolete TLP732(GR-LF1,F) based on the following factors:

• Product Lifecycle: The TLP785 maintains active product status, ensuring continued availability, technical support, and manufacturing consistency. The TLP732 obsolescence status creates supply risk and limits long-term design viability.
• Regulatory Compliance: The TLP785 carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for component procurement and end-product distribution.
• Export Classification: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring no change to export control or tariff treatment.
• Functional Specifications: The TLP785 provides defined electrical parameters including 5000Vrms isolation voltage, transistor output configuration, and specified operating temperature range, enabling precise circuit design and validation.

Frequently Asked Questions (FAQ)

Q: Can the TLP785(GR-LF6,F) be used as a direct pin-for-pin replacement for the TLP732(GR-LF1,F)?

A: The TLP785 is functionally equivalent as an optoisolator transistor output device. However, physical package compatibility must be verified against the original design documentation. The TLP785 is specified in 4-SMD, Gull Wing package format. Confirm that the PCB footprint and mounting requirements align with the original TLP732 implementation.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by isolation voltage rating (5000Vrms for TLP785), output type (transistor configuration), number of channels (1 channel), maximum output voltage (80V), and maximum output current per channel (50mA). These parameters must satisfy the circuit requirements of the original application.

Q: Does the TLP785 meet current environmental and regulatory standards?

A: Yes. The TLP785(GR-LF6,F) is ROHS3 compliant and carries EAR99 export classification, meeting current environmental regulations and export control requirements. The TLP732, as an obsolete component, may not meet current compliance standards.

Q: Are there any supply chain or availability differences between these components?

A: The TLP732 is obsolete with limited remaining inventory. The TLP785 maintains active product status with established supply chains through Toshiba Semiconductor and Storage, ensuring reliable long-term procurement and consistent manufacturing quality.

Q: What packaging considerations apply to the TLP785 substitute?

A: The TLP785(GR-LF6,F) is supplied in 4-SMD, Gull Wing surface mount package format. Verify that your manufacturing process supports surface mount assembly and that the PCB design accommodates the specified package dimensions and lead configuration.
