Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP700AF(F) is determined by strict equivalence across the following critical parameters:

Isolation Voltage: Both the main part and substitute must maintain 5000Vrms isolation rating to preserve system safety margins and regulatory compliance.

Channel Configuration: Single-channel topology is required to match the original circuit interface.

Common Mode Transient Immunity: The 20kV/µs minimum specification ensures the substitute can handle rapid voltage transitions without false triggering.

Propagation Delay: Maximum specifications of 200ns for both rising and falling edges must be met to maintain timing-critical gate drive performance.

Output Current Capability: Peak output current of 2.5A is the baseline requirement for gate driver functionality.

Supply Voltage Range: The 15V to 30V operating range must be supported by the substitute.

Temperature Range: Operating temperature limits of -40°C to 110°C define the thermal operating envelope.

Package Type: Surface mount 6-SOIC packaging ensures mechanical and thermal compatibility with existing PCB designs.

The TLP5702(LF4,E) meets all these criteria and is classified as an active product, providing long-term availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The TLP5702(LF4,E) is the direct functional equivalent for the obsolete TLP700AF(F). Both devices are manufactured by Toshiba Semiconductor and Storage and share identical electrical specifications across all critical parameters including isolation voltage, propagation delay, common mode transient immunity, and operating temperature range.

Product Status Advantage: The TLP5702(LF4,E) is classified as an active product with confirmed inventory of 942 pieces in stock. This ensures long-term availability, ongoing manufacturing support, and compliance with current industry standards. The TLP700AF(F), being obsolete, presents supply chain risk and potential end-of-life discontinuation.

Package Compatibility: Both devices use 6-SOIC surface mount packaging. The TLP5702(LF4,E) has a slightly wider body (7.50mm versus 6.80mm), but this remains within standard 6-SOIC tolerance specifications and is compatible with existing PCB layouts designed for 6-SOIC footprints.

Regulatory Compliance: The TLP700AF(F) carries multiple approval agencies (CQC, CSA, cUL, UL, VDE). While specific certifications for the TLP5702(LF4,E) are not provided in the available data, both parts share the same manufacturer and base product lineage, indicating equivalent compliance standards.

Moisture Sensitivity: The TLP5702(LF4,E) is rated MSL 1 (Unlimited), indicating superior moisture handling characteristics compared to typical optoisolators.

Selection of the TLP5702(LF4,E) for new designs and obsolescence replacement is supported by complete electrical equivalence and active product status.

Frequently Asked Questions (FAQ)

Q: Can the TLP5702(LF4,E) directly replace the TLP700AF(F) in existing designs?

A: Yes. The TLP5702(LF4,E) meets all electrical specifications of the TLP700AF(F) including isolation voltage, propagation delay, CMTI, output current, and operating temperature range. Both use 6-SOIC surface mount packaging. The package width difference (7.50mm versus 6.80mm) remains within standard 6-SOIC specifications and is compatible with existing PCB footprints.

Q: What is the primary reason for substitution?
