TLP620F-2(F) Equivalent & Substitute Parts

Part Overview

The TLP620F-2(F) is an optoisolator (photocoupler) manufactured by Toshiba Semiconductor and Storage, designed for high-voltage isolation applications. This component features a single channel with 5000Vrms isolation rating and is packaged in an 8-DIP through-hole configuration. The device is classified as obsolete, making identification of suitable substitute components essential for ongoing design support, maintenance, and new production requirements. The TLP620F-2(F) provides galvanic isolation between input and output circuits while maintaining signal integrity across the isolation barrier.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP620F-2(F) is determined by the following critical electrical and mechanical parameters:

Isolation Voltage: The substitute must maintain the 5000Vrms isolation rating to preserve circuit safety and regulatory compliance.

Number of Channels: Single-channel configuration is required to match the original design topology.

Current Transfer Ratio Range: The substitute must operate within the 50% to 600% @ 5mA range to ensure compatible signal transfer characteristics.

Output Current Capability: The substitute must support 50mA output current per channel to meet load requirements.

Operating Temperature Range: The substitute must cover the -55°C to 100°C operating window or exceed it.

Mounting Type and Package Compatibility: Through-hole mounting is specified; however, package form factor changes may be accommodated if electrical parameters remain compatible and circuit board layout permits physical substitution.

Regulatory Compliance: Both ECCN EAR99 and HTSUS 8541.49.8000 classifications must be maintained.

The TLP620MF(E) is identified as a manufacturer-recommended substitute based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The TLP620MF(E) is the manufacturer-recommended substitute for the obsolete TLP620F-2(F). Both components are manufactured by Toshiba Semiconductor and Storage and share identical isolation voltage (5000Vrms), channel count (1), and current transfer ratio specifications (50% to 600% @ 5mA).

Product Status Consideration: The TLP620F-2(F) is classified as obsolete, while the TLP620MF(E) maintains active product status. This transition ensures continued availability and manufacturing support for new designs and production requirements.

Regulatory Compliance: Both parts carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, confirming equivalent export control and tariff treatment.

Electrical Compatibility: The TLP620MF(E) provides enhanced performance characteristics, including higher maximum output voltage (80V versus 55V) and extended operating temperature range (-55°C to 125°C versus -55°C to 100°C). These improvements ensure the substitute operates within or exceeds the original design envelope.

Package Consideration: The substitute uses a 4-DIP package (0.400", 10.16mm) compared to the original 8-DIP package (0.300", 7.62mm). Circuit board layout modification is required to accommodate this package change. Both maintain through-hole mounting technology.

Input/Output Characteristics: The TLP620MF(E) specifies transistor output type with defined switching characteristics (3µs turn-on/off time, 2µs/3µs rise/fall time) and accepts both AC and DC input signals, providing enhanced design flexibility compared to the original part.

Frequently Asked Questions (FAQ)

Q: Can the TLP620MF(E) directly replace the TLP620F-2(F) without circuit modifications?

A: Electrical substitution is valid based on isolation voltage, channel count, and current transfer ratio specifications. However, the package change from 8-DIP to 4-DIP requires circuit board layout modification. Pin-to-pin functional compatibility must be verified against the specific application schematic.

Q: What is the significance of the package size difference between these components?

A: The TLP620F-2(F) uses an 8-DIP package (0.300" width), while the TLP620MF(E) uses a 4-DIP package (0.400" width). The 4-DIP package is more compact in terms of pin count but has a larger body width. Circuit board routing and component placement must be re-evaluated for the substitute part.

Q: Are there any electrical performance differences that affect circuit design?

A: The TLP620MF(E) provides higher maximum output voltage (80V versus 55V) and extended operating temperature range (-55°C to 125°C versus -55°C to 100°C). These represent performance improvements that do not negatively impact designs specified for the original part. The substitute's maximum forward current is 50mA versus 60mA for the original; this difference is within typical design margins for 50mA output current applications.

Q: Why is the TLP620F-2(F) classified as obsolete?

A: Obsolescence reflects the manufacturer's decision to discontinue production. The TLP620MF(E) represents the active product line continuation, offering equivalent or superior electrical characteristics with ongoing manufacturing support.

Q: Are regulatory certifications identical between these parts?

A: Yes. Both the TLP620F-2(F) and TLP620MF(E) carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, confirming equivalent regulatory treatment for export control and tariff purposes.

Q: What input signal types does the substitute support?

A: The TLP620MF(E) accepts both AC and DC input signals, providing greater design flexibility than the original part specification. This capability does not restrict operation in DC-only applications.

Q: Is the 5000Vrms isolation rating maintained in the substitute?

A: Yes. The TLP620MF(E) maintains the 5000Vrms isolation voltage specification, preserving the high-voltage isolation capability required for safety-critical applications.
