• Both maintain MSL rating of 1 (Unlimited), indicating identical moisture sensitivity handling
• The TLP2768A(E) provides active product status, ensuring long-term availability and supply chain continuity
• Single-channel isolation architecture maintained across both parts
• Surface mount packaging enables direct integration into modern PCB designs

Parameter Comparison

Engineering Selection Recommendations

The TLP2768A(E) is the designated substitute for the obsolete TLP552 based on manufacturer alignment, regulatory compliance, and product lifecycle status. Both components share identical MSL classification and export control designations, ensuring equivalent handling and compliance requirements. The TLP2768A(E) maintains active product status with ROHS3 compliance and REACH unaffected certification, providing regulatory assurance for new designs and legacy system updates. Surface mount packaging in 6-SOIC format enables direct PCB integration without requiring design modifications beyond footprint verification.

Frequently Asked Questions (FAQ)

Q: Can the TLP2768A(E) directly replace the TLP552 in existing designs?

A: Direct replacement requires footprint compatibility verification. The TLP2768A(E) uses 6-SOIC (0.295", 7.50mm Width) surface mount packaging. Original TLP552 packaging specifications are not provided; physical layout confirmation is necessary before implementation.

Q: What are the key differences between these optoisolators?

A: The TLP2768A(E) specifies 5000Vrms isolation voltage, open collector output with Schottky clamping, and 20MBd data rate capability. The TLP552 detailed electrical specifications are not available in the provided documentation. Functional validation against application requirements is required.

Q: Are there compliance differences between the two parts?

A: Both components share identical MSL (1 - Unlimited), ECCN (EAR99), and HTSUS (8541.49.8000) classifications. The TLP2768A(E) adds ROHS3 compliance and REACH unaffected certification, providing enhanced regulatory coverage for modern applications.

Q: Why is the TLP552 obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The TLP2768A(E) represents the active equivalent within Toshiba's optoisolator portfolio, ensuring continued supply chain access and technical support.

Q: What supply chain considerations apply to this substitution?

A: The TLP552 is obsolete with no ongoing production. The TLP2768A(E) maintains active status with 961 pieces in current inventory, providing immediate availability for component procurement and system integration.
