Engineering Selection Recommendations

The TLP2766A(E) is the direct manufacturer-recommended substitute for the obsolete TLP2766(F). Both components share identical electrical specifications, isolation ratings, and functional characteristics. The TLP2766A(E) carries active product status from Toshiba Semiconductor and Storage, ensuring ongoing availability and manufacturing support.

Both parts maintain equivalent compliance classifications under ECCN EAR99 and HTSUS 8541.49.8000, confirming regulatory alignment for procurement and export purposes.

The primary distinction between these components lies in packaging format and rise/fall time performance. The TLP2766(F) utilizes a 6-SDIP gull wing package with 15ns typical rise and fall times, while the TLP2766A(E) employs a 6-SO package with improved 5ns and 4ns rise and fall times respectively. Both packages are surface mount configurations suitable for automated assembly processes.

For new designs or system replacements, the TLP2766A(E) is the appropriate selection due to its active product status and superior timing characteristics.

Frequently Asked Questions (FAQ)

Q: Can the TLP2766A(E) directly replace the TLP2766(F) in existing designs?

A: Yes. The TLP2766A(E) meets all critical electrical and functional specifications of the TLP2766(F), including isolation voltage, CMTI rating, data rate, output current, and supply voltage range. Both components are single-channel optoisolators with identical push-pull totem pole output configurations.

Q: What is the difference between the 6-SDIP and 6-SO packages?

A: The 6-SDIP gull wing package measures 0.268 inches (6.80mm) in width, while the 6-SO package measures 0.295 inches (7.50mm) in width. Both are surface mount packages. PCB layout and footprint designs must accommodate the specific package geometry of the selected component.

Q: Are there timing differences between these parts?

A: Propagation delay specifications are identical at 55ns maximum for both rising and falling edges. However, the TLP2766A(E) exhibits faster rise and fall times (5ns and 4ns typical) compared to the TLP2766(F) (15ns typical for both). This represents improved performance in the substitute part.

Q: Why is the TLP2766(F) classified as obsolete?

A: The TLP2766(F) has been superseded by the TLP2766A(E) in Toshiba's active product portfolio. The manufacturer recommends transitioning to the TLP2766A(E) for new applications and ongoing support.

Q: Are the forward voltage specifications identical?

A: The TLP2766(F) specifies 1.55V typical forward voltage, while the TLP2766A(E) specifies 1.8V maximum forward voltage. Both operate within the same 2.7V to 5.5V supply voltage range and maintain equivalent DC forward current limits of 25mA maximum.

Q: What is the moisture sensitivity level of the TLP2766A(E)?

A: The TLP2766A(E) carries MSL 1 (Unlimited) classification, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do both parts support the same operating temperature range?

A: Yes. Both the TLP2766(F) and TLP2766A(E) operate across the -40°C to 125°C temperature range.
