Substitute Part Grouping Explanation

Substitution of the obsolete TLP512 is based on the following criteria derived from the provided specifications:

Primary Substitution Criteria:

• Category classification: Optoisolators
• Manufacturer: Toshiba Semiconductor and Storage (same manufacturer preferred for design consistency)
• Product Status: Active (to ensure ongoing availability)
• Regulatory compliance: ECCN EAR99 and HTSUS 8541.49.8000 classification maintained
• Moisture Sensitivity Level: MSL 1 (Unlimited) for equivalent handling requirements

The TLP2719(TP,E represents an active substitute within the Toshiba optoisolator product line, maintaining the same regulatory classification and moisture sensitivity characteristics while offering enhanced specifications for modern applications.

Parameter Comparison

Engineering Selection Recommendations

The TLP2719(TP,E is the designated substitute for the obsolete TLP512 based on the following engineering factors:

Product Status and Availability: The TLP512 is obsolete with no ongoing manufacturing. The TLP2719(TP,E is an active product with confirmed inventory of 4820 pieces, ensuring supply chain continuity for both new designs and field service requirements.

Regulatory and Compliance Alignment: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining export control and tariff compliance. The TLP2719(TP,E achieves ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards.

Moisture Sensitivity Consistency: Both parts maintain MSL 1 (Unlimited) classification, requiring no changes to handling, storage, or assembly procedures.

Functional Compatibility: The TLP2719(TP,E operates as a logic output optoisolator with specified isolation voltage of 5000Vrms, common mode transient immunity of 10kV/µs, and open collector output configuration suitable for digital isolation applications.

Frequently Asked Questions (FAQ)

Q: Can the TLP2719(TP,E directly replace the TLP512 in existing designs?

A: Substitution feasibility depends on the specific electrical requirements of the original design. The TLP2719(TP,E provides documented specifications including 5000Vrms isolation, 1MBd data rate, and open collector output. Verify that these parameters meet or exceed the original design requirements before implementation.

Q: What are the key differences in package configuration?

A: The TLP2719(TP,E is supplied in 6-SOIC (0.295", 7.50mm Width) surface mount package with Tape & Reel (TR) packaging. Confirm PCB layout compatibility with this package geometry and surface mount assembly process requirements.

Q: Are there any compliance considerations for substitution?

A: Both components maintain identical ECCN and HTSUS classifications. The TLP2719(TP,E additionally provides ROHS3 compliance and REACH unaffected status, which may be required for applications subject to environmental regulations.

Q: What is the supply status for the TLP2719(TP,E?

A: The TLP2719(TP,E is an active product with 4820 pieces in current inventory, providing reliable long-term availability compared to the obsolete TLP512.

Q: How do the electrical specifications compare?

A: The TLP2719(TP,E specifies 1 channel, 8 mA output current, 1.6V typical forward voltage, 25 mA maximum DC forward current, and operating temperature range of -40°C to 100°C. Confirm these parameters align with circuit design requirements.
