Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLPN137(TP1,S) is based on the following critical parameters derived from the provided specifications:

• Manufacturer Continuity: Toshiba Semiconductor and Storage maintains product line compatibility within its optoisolator portfolio
• Functional Category: Logic output optoisolator with high-speed isolation capability
• Isolation Voltage Class: Devices must support equivalent or higher isolation voltage ratings
• Channel Configuration: Single-channel architecture
• Output Type: Logic-level output suitable for digital circuit interfacing
• Compliance Status: RoHS and REACH compliance for modern procurement requirements

The TLP2768A(TP,E) qualifies as a direct substitute based on these parameters, offering active product status with enhanced specifications within the same functional category.

Engineering Selection Recommendations

The TLP2768A(TP,E) is the qualified substitute for the obsolete TLPN137(TP1,S) based on the following engineering criteria:

• Product Status Alignment: The TLP2768A(TP,E) maintains active product status, ensuring long-term availability and manufacturing support from Toshiba Semiconductor and Storage
• Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS classifications. The TLP2768A(TP,E) carries explicit RoHS3 compliance and REACH unaffected status, meeting modern procurement and environmental standards
• Functional Compatibility: Both devices operate as single-channel optoisolators within the Toshiba logic output optoisolator family, maintaining functional equivalence for isolation applications
• Moisture Sensitivity: Identical MSL rating of 1 (Unlimited) ensures equivalent handling and storage requirements
• Supply Chain Continuity: Current inventory of 3943 units of TLP2768A(TP,E) supports immediate procurement, compared to the obsolete status of the original part

Frequently Asked Questions (FAQ)

Q: Can the TLP2768A(TP,E) directly replace the TLPN137(TP1,S) in existing designs?

A: The TLP2768A(TP,E) is functionally equivalent as a single-channel logic output optoisolator from the same manufacturer. However, package differences must be verified. The TLP2768A(TP,E) uses a 6-SOIC package; confirm that your PCB layout accommodates this form factor before implementation.

Q: What are the key differences between these two parts?

A: The primary differences are product status (obsolete vs. active) and explicit specification documentation. The TLP2768A(TP,E) provides detailed electrical parameters including 5000Vrms isolation voltage, 20kV/µs CMTI, and 20MBd data rate. The TLPN137(TP1,S) specifications are not fully documented in available references, making the TLP2768A(TP,E) the recommended active alternative.

Q: Are there any compliance concerns with substitution?

A: No. Both parts share identical ECCN and HTSUS classifications. The TLP2768A(TP,E) carries explicit RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for new designs and procurement.

Q: What packaging format is the TLP2768A(TP,E) available in?

A: The TLP2768A(TP,E) is supplied in Tape & Reel (TR) format with a 6-SOIC surface mount package measuring 0.295" × 7.50mm width. Verify compatibility with your assembly process and equipment specifications.

Q: Is the moisture sensitivity level the same for both parts?

A: Yes. Both the TLPN137(TP1,S) and TLP2768A(TP,E) carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions and identical handling requirements.
