Key Parameters

Substitute Part Grouping Explanation

The TLP627M(TP1,E) series qualifies as a functional substitute based on the following alignment criteria:

Common Classification Parameters:

• Category: Optoisolators (both single-channel isolation devices)
• Manufacturer: Toshiba Semiconductor and Storage (same manufacturer ecosystem)
• Moisture Sensitivity Level: 1 (Unlimited) — identical environmental rating
• ECCN Classification: EAR99 — matching export control designation
• HTSUS Code: 8541.49.8000 — identical tariff classification

Substitution Logic: The TLP627M series represents an active product line within Toshiba's optoisolator portfolio. While the TLP571 is obsolete, the TLP627M maintains equivalent isolation functionality and environmental specifications, making it suitable for replacement in applications where the TLP571 was previously specified. Both parts share identical MSL ratings and regulatory classifications, ensuring compliance continuity.

Engineering Selection Recommendations

Primary Substitute: TLP627M(TP1,E)

The TLP627M(TP1,E) is the recommended substitute for the obsolete TLP571(TP1,F). Selection is based on:

• Product Status Alignment: TLP627M is an active product with confirmed inventory availability (722 Pcs New Original In Stock), ensuring long-term procurement viability compared to the obsolete TLP571.
• Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining compliance requirements without modification.
• Environmental Rating: Identical MSL 1 (Unlimited) rating ensures equivalent moisture sensitivity handling and storage requirements.
• Manufacturer Continuity: Both parts originate from Toshiba Semiconductor and Storage, maintaining design ecosystem consistency.

Packaging Consideration:

The TLP627M(TP1,E) is supplied in Tape & Reel (TR) packaging with 4-SMD, Gull Wing configuration. Design integration requires verification that surface-mount assembly processes and PCB layout accommodate this package type.

Frequently Asked Questions (FAQ)

Q: Why is the TLP571(TP1,F) being replaced?
