Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP570(HITM,F) is determined by the following critical parameters:

• Category Alignment: Both the main part and substitute must function as optoisolators within the same product category
• Number of Channels: Single-channel configuration requirement
• Manufacturer Consistency: Toshiba Semiconductor and Storage maintains design compatibility across the TLP series
• Isolation Voltage: Electrical isolation capability must meet or exceed application requirements
• Output Configuration: Output type and maximum voltage/current ratings must support the intended circuit topology
• Packaging and Mounting: Physical form factor and mounting method must be compatible with existing PCB designs
• Regulatory Compliance: ECCN and HTSUS classifications ensure consistent export and trade compliance

The TLP627M(E) qualifies as a substitute based on shared manufacturer origin, single-channel optoisolator architecture, and compatible electrical isolation specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLP627M(E) is an active-status substitute for the obsolete TLP570(HITM,F). Both components share identical manufacturer origin, regulatory classification (ECCN EAR99, HTSUS 8541.49.8000), and moisture sensitivity specifications. The TLP627M(E) provides documented electrical specifications including 5000Vrms isolation voltage, Darlington output configuration, and 150mA maximum output current per channel, supporting single-channel optoisolation requirements.

Selection of the TLP627M(E) as a replacement is justified by:

• Active product status ensuring ongoing availability and supply chain continuity
• Consistent regulatory compliance and trade classification
• Single-channel architecture matching the original design requirement
• Through-hole 4-DIP packaging compatible with legacy PCB layouts
• Documented thermal operating range of -55°C to 110°C

Frequently Asked Questions (FAQ)

Q: Why is the TLP570(HITM,F) marked as obsolete?

A: The TLP570(HITM,F) has reached end-of-life status with Toshiba Semiconductor and Storage. The TLP627M(E) represents the active-status equivalent within the TLP optoisolator product line, ensuring continued design support and component availability.

Q: Are the TLP570(HITM,F) and TLP627M(E) pin-compatible?

A: Both components use 4-DIP through-hole packaging. Pin compatibility must be verified against detailed pinout documentation for your specific application circuit topology.

Q: What is the isolation voltage difference between these parts?

A: The TLP627M(E) specifies 5000Vrms isolation voltage. The TLP570(HITM,F) isolation voltage is not provided in available documentation. Application requirements must be evaluated against the TLP627M(E) specification.

Q: Can I use the TLP627M(E) in all applications where the TLP570(HITM,F) was used?

A: Substitution feasibility depends on your specific circuit requirements including isolation voltage, output current, and output type (Darlington configuration). Verify that the TLP627M(E) electrical specifications meet or exceed your application demands.

Q: What is the current transfer ratio of the TLP627M(E)?

A: The TLP627M(E) specifies a maximum current transfer ratio of 1000% at 1mA input current, with typical turn-on and turn-off times of 110µs and 30µs respectively.

Q: Are both parts subject to the same export regulations?

A: Yes. Both the TLP570(HITM,F) and TLP627M(E) share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, ensuring consistent regulatory treatment in procurement and export compliance.
