Key Parameters

Substitute Part Grouping Explanation

The TLP785(BL,F) qualifies as a substitute for the TLP632(BL,F) based on the following alignment criteria:

Common Classification Parameters:

• Category: Both are optoisolators (photocouplers)
• Manufacturer: Both manufactured by Toshiba Semiconductor and Storage
• Moisture Sensitivity Level: Both rated MSL 1 (Unlimited)
• Export Classification: Both classified as ECCN EAR99
• Tariff Code: Both assigned HTSUS 8541.49.8000

Functional Compatibility:

• Number of Channels: Both feature single-channel configuration
• Output Type: Both utilize transistor output architecture
• Input Type: Both accept DC input

The TLP785(BL,F) is an active product, providing ongoing availability and support compared to the obsolete TLP632(BL,F).

Parameter Comparison

Engineering Selection Recommendations

For Active Production and New Designs: The TLP785(BL,F) is the appropriate selection. As an active product with current manufacturing support, it provides supply chain continuity and compliance with ongoing component lifecycle management. Both parts share identical export classification (ECCN EAR99) and tariff coding (HTSUS 8541.49.8000), ensuring regulatory consistency.

For Legacy System Maintenance: The TLP632(BL,F) remains available in inventory (755 units) for applications requiring exact original component replacement. However, transition planning to the TLP785(BL,F) is recommended for long-term sustainability, given the obsolete status of the TLP632(BL,F).

Compliance Considerations: Both components carry MSL 1 (Unlimited) moisture sensitivity rating, indicating no moisture-related handling restrictions during storage, transport, or assembly.

Frequently Asked Questions (FAQ)

Q: Can the TLP785(BL,F) directly replace the TLP632(BL,F) in existing designs?

A: Both components are single-channel optoisolators with transistor output architecture from the same manufacturer. Substitution is valid based on shared functional classification. However, verify that the TLP785(BL,F) electrical specifications (isolation voltage 5000Vrms, output current 50mA, operating temperature -55°C ~ 110°C) meet or exceed the requirements of your specific application.

Q: What is the difference in packaging between these parts?

A: The TLP785(BL,F) is supplied in Tube packaging. The TLP632(BL,F) packaging specification is not provided in the available data. Confirm packaging compatibility with your assembly process and equipment.

Q: Why is the TLP632(BL,F) listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production and support. The TLP785(BL,F) represents the active equivalent within Toshiba's optoisolator product line.

Q: Are there any export or tariff considerations when substituting these parts?

A: Both components share identical export classification (ECCN EAR99) and tariff code (HTSUS 8541.49.8000). No change in regulatory or customs treatment occurs when substituting between these parts.

Q: What inventory considerations should I account for?

A: The TLP632(BL,F) has 755 units in stock, while the TLP785(BL,F) has 908 units available. For ongoing production, the TLP785(BL,F) offers greater supply availability and long-term sourcing stability due to its active product status.
