Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP331(BV-LF1,F) are identified based on the following critical parameters that define functional equivalence within the optoisolator category:

• Manufacturer: Toshiba Semiconductor and Storage (same manufacturer ensures design continuity and reliability standards)
• Category: Optoisolators (maintains functional classification)
• Moisture Sensitivity Level: 1 (Unlimited) (ensures equivalent handling and storage requirements)
• Export Classification: EAR99 (maintains regulatory compliance)
• HTSUS Code: 8541.49.8000 (confirms tariff classification alignment)

The TLP383(BL,E) qualifies as a substitute part based on these core parameters. While the TLP383 is an active product with enhanced specifications (transistor output configuration, 5000Vrms isolation voltage, and defined electrical performance metrics), it maintains the same manufacturer, category classification, moisture sensitivity level, and regulatory compliance framework as the obsolete TLP331.
