Substitute Part Grouping Explanation

Substitution of the TLP2768(D4-TP,F) is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Isolation voltage: 5000Vrms
• Common mode transient immunity: 20kV/µs minimum
• Data rate: 20MBd
• Output configuration: Open collector, Schottky clamped
• Output current capability: 25 mA per channel
• Propagation delay: 60ns maximum (both rising and falling edges)
• Supply voltage range: 2.7V to 5.5V
• Operating temperature range: -40°C to 125°C

Mechanical Equivalence Criteria:

• Mounting type: Surface mount
• Package family: 6-pin SOIC variants

The TLP2768A(D4-TP,E) qualifies as a direct substitute based on identical electrical specifications and compatible surface mount packaging. The primary distinction is product status: the substitute part is active and available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TLP2768A(D4-TP,E) is the direct substitute for the obsolete TLP2768(D4-TP,F). Both parts are manufactured by Toshiba Semiconductor and Storage and share identical electrical specifications across all critical parameters including isolation voltage, CMTI, data rate, output configuration, and timing characteristics.

Selection Basis:

1. Product Status: The TLP2768A(D4-TP,E) is active and currently in production, ensuring long-term availability and supply chain continuity. The original TLP2768(D4-TP,F) is obsolete and subject to discontinuation.

2. Electrical Compatibility: All functional parameters are identical, enabling direct functional replacement without circuit redesign or performance degradation.

3. Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining compliance with export and tariff requirements.

4. Packaging Compatibility: Both parts use 6-pin SOIC surface mount packages. The TLP2768A(D4-TP,E) features a slightly wider body (7.50mm versus 6.80mm), which remains compatible with standard 6-SOIC footprints used in PCB designs.

5. Moisture Sensitivity: The TLP2768A(D4-TP,E) specifies MSL 1 (Unlimited), indicating superior moisture handling characteristics compared to the original part.

For new designs and production applications, the TLP2768A(D4-TP,E) is the appropriate selection. For field replacements of existing TLP2768(D4-TP,F) installations, the TLP2768A(D4-TP,E) provides functional equivalence without requiring circuit modifications.

Frequently Asked Questions (FAQ)

Q: Can the TLP2768A(D4-TP,E) be used as a direct replacement for the TLP2768(D4-TP,F) in existing designs?

A: Yes. The TLP2768A(D4-TP,E) is electrically and functionally equivalent to the TLP2768(D4-TP,F) across all specified parameters. No circuit modifications are required for substitution.

Q: What is the difference between the two package designations (6-SDIP Gull Wing versus 6-SO)?

A: Both designations refer to 6-pin SOIC surface mount packages. The TLP2768(D4-TP,F) uses a 6-SDIP Gull Wing package with 6.80mm body width, while the TLP2768A(D4-TP,E) uses a standard 6-SO package with 7.50mm body width. Both are compatible with standard 6-SOIC PCB footprints.

Q: Why is the TLP2768(D4-TP,F) classified as obsolete?

A: The TLP2768(D4-TP,F) has been discontinued by the manufacturer. The TLP2768A(D4-TP,E) represents the active replacement in the product line.

Q: Are the isolation voltage and CMTI specifications identical between the two parts?

A: Yes. Both parts provide 5000Vrms isolation voltage and 20kV/µs common mode transient immunity. These critical parameters are unchanged between the original and substitute part.

Q: What is the significance of the MSL 1 rating on the TLP2768A(D4-TP,E)?

A: MSL 1 (Unlimited) indicates that the substitute part has no moisture sensitivity limitations and does not require special handling or storage conditions. This improves manufacturing flexibility and reduces component handling costs.

Q: Are the propagation delay and rise/fall time specifications the same?

A: Yes. Both parts specify maximum propagation delay of 60ns for both rising and falling edges, and typical rise/fall times of 30ns. Timing performance is identical.

Q: Can both parts operate across the same supply voltage range?

A: Yes. Both the TLP2768(D4-TP,F) and TLP2768A(D4-TP,E) operate with supply voltages from 2.7V to 5.5V and across the same temperature range of -40°C to 125°C.
