TLP550 Equivalent & Substitute Parts

Part Overview

The TLP550 is an optoisolator manufactured by Toshiba Semiconductor and Storage, designed for photocoupler applications requiring electrical isolation between input and output circuits. The product is classified as obsolete, necessitating identification of active equivalent components for continued system design and maintenance. Substitute parts must maintain functional compatibility across isolation voltage, channel configuration, and output characteristics.

Key Parameters

Substitute Part Grouping Explanation

The TLP2719 is identified as a substitute for the TLP550 based on the following substitution criteria:

• Both components are optoisolators manufactured by Toshiba Semiconductor and Storage
• Both fall under HTSUS classification 8541.49.8000
• Both maintain MSL rating of 1 (Unlimited)
• Both comply with ECCN EAR99 export classification
• The TLP2719 provides active product status with documented electrical specifications suitable for isolation applications

Substitution is valid when system requirements align with the TLP2719 electrical and mechanical specifications, particularly isolation voltage rating, channel count, and output type.

Parameter Comparison

Engineering Selection Recommendations

The TLP2719 is suitable as a substitute for the TLP550 based on regulatory and compliance alignment. Both components share identical MSL classification, ECCN designation, and HTSUS coding, ensuring consistency in supply chain documentation and export compliance.

The TLP2719 maintains active product status with documented availability, addressing the obsolescence of the TLP550. Selection of the TLP2719 requires verification that system design accommodates the specified electrical parameters: 5000Vrms isolation voltage, single-channel configuration, open-collector output topology, and 6-SOIC surface-mount packaging.

Frequently Asked Questions (FAQ)

Q: Why is the TLP550 being replaced? A: The TLP550 is classified as obsolete. The TLP2719 provides an active alternative from the same manufacturer with documented electrical specifications and current inventory availability.

Q: What are the key compatibility criteria between TLP550 and TLP2719? A: Both components are optoisolators with identical MSL, ECCN, and HTSUS classifications. The TLP2719 specifies 5000Vrms isolation voltage, single-channel configuration, and open-collector output. System design must accommodate these electrical characteristics.

Q: Does the TLP2719 require different PCB layout considerations? A: The TLP2719 uses 6-SOIC surface-mount packaging. Design verification is required to confirm compatibility with existing PCB footprints and assembly processes.

Q: Are there any supply chain or compliance differences? A: Both components maintain identical regulatory classifications (ECCN EAR99, HTSUS 8541.49.8000) and MSL ratings. No additional compliance documentation is required for substitution.
