Substitute Part Grouping Explanation

The TLP785(GR-LF6,F) qualifies as a substitute for the TLP732(GR-LF4,F) based on the following alignment criteria:

Common Classification Parameters:

• Category: Both are optoisolators
• Manufacturer: Both manufactured by Toshiba Semiconductor and Storage
• Functional Type: Both feature transistor output configurations
• Isolation Voltage: Both rated at 5000Vrms isolation
• ECCN Classification: Both classified as EAR99
• HTSUS Code: Both assigned 8541.49.8000

Substitution Logic: The TLP785(GR-LF6,F) maintains electrical and functional compatibility through shared isolation voltage rating, transistor output topology, and regulatory classification. The substitute part is currently in active production status, providing supply continuity for the obsolete TLP732 base product line.

Parameter Comparison

Engineering Selection Recommendations

For Obsolete Part Replacement: The TLP785(GR-LF6,F) is the designated substitute for the obsolete TLP732(GR-LF4,F). Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring regulatory compliance continuity. The TLP785 maintains active production status, providing long-term supply security compared to the obsolete TLP732.

Compliance Considerations: Both parts comply with RoHS3 standards where applicable. The TLP785(GR-LF6,F) carries explicit RoHS3 Compliant certification. Regulatory classification alignment ensures that substitution does not introduce compliance complications in export or procurement workflows.

Stock Availability: While the TLP732 maintains 1,070 units in current inventory, the TLP785 is actively produced with 801 units available. For new designs or long-term production requirements, the TLP785 is the recommended selection due to its active status and continued manufacturing support.

Frequently Asked Questions (FAQ)

Q: Why is the TLP732(GR-LF4,F) being phased out? A: The TLP732 is classified as obsolete. The TLP785(GR-LF6,F) represents the active product line continuation from Toshiba Semiconductor and Storage for this optoisolator category.

Q: Are the TLP732 and TLP785 electrically interchangeable? A: Both components are classified as optoisolators with transistor output configurations and share the same 5000Vrms isolation voltage rating. They maintain identical regulatory classifications (EAR99, HTSUS 8541.49.8000), supporting functional substitution within the specified parameter set.

Q: What are the packaging differences? A: The TLP732(GR-LF4,F) packaging is not specified in available documentation. The TLP785(GR-LF6,F) is supplied in 4-SMD, Gull Wing surface mount package configuration. Physical footprint verification is required before substitution in existing PCB designs.

Q: Can I use remaining TLP732 stock in new designs? A: The TLP732 is obsolete with limited remaining stock (1,070 units). For new product development, the TLP785(GR-LF6,F) is recommended to ensure long-term supply continuity and manufacturing support.

Q: Are there regulatory compliance differences between the two parts? A: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. The TLP785 explicitly carries RoHS3 Compliant certification. No compliance complications arise from substitution.

Q: What isolation voltage rating applies to both parts? A: Both the TLP732 and TLP785 are rated for 5000Vrms isolation voltage, supporting equivalent electrical performance in isolation-critical applications.
