TLP626(FUJI,F) Equivalent & Substitute Parts

Part Overview

The TLP626(FUJI,F) is an optoisolator with transistor output manufactured by Toshiba Semiconductor and Storage. This component provides galvanic isolation up to 5000Vrms with a single channel configuration in a 4-DIP through-hole package. The device accepts both AC and DC input signals and delivers transistor-based output suitable for switching applications up to 50mA per channel.

The TLP626(FUJI,F) is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where this component is specified in existing designs.

Substitute Part Grouping Explanation

Substitution of the TLP626(FUJI,F) is determined by the following critical parameters:

Isolation Voltage: The substitute must maintain 5000Vrms isolation rating to preserve galvanic separation in the application circuit.

Package Configuration: The substitute must use the same 4-DIP through-hole package (0.300", 7.62mm) to ensure mechanical and electrical compatibility with existing PCB layouts and socket configurations.

Output Type: The substitute must provide transistor output to maintain functional equivalence with the original switching behavior.

Current Capacity: The substitute must support a minimum of 50mA output current per channel to handle the load requirements of the original design.

Input Signal Type: The substitute must accept both AC and DC input signals to support the full range of input conditions specified for the original component.

Operating Temperature: The substitute must cover the operating temperature range or provide a superset of the original range (-55°C ~ 100°C).

The TLP620M(E) meets all these substitution criteria and is classified as an active product, providing long-term availability and supply chain stability.

Engineering Selection Recommendations

The TLP620M(E) is the qualified substitute for the TLP626(FUJI,F) based on the following engineering criteria:

Functional Equivalence: Both components share identical isolation voltage (5000Vrms), channel count (1), output type (transistor), and output current capacity (50mA). The package footprint and mounting method are identical, enabling direct replacement without PCB redesign.

Product Status Advantage: The TLP626(FUJI,F) is obsolete, creating supply chain risk. The TLP620M(E) is classified as active, ensuring continued availability and manufacturing support from Toshiba Semiconductor and Storage.

Performance Enhancement: The TLP620M(E) provides superior electrical characteristics including lower Vce saturation (300mV versus 400mV), higher maximum output voltage (80V versus 55V), and extended operating temperature range (-55°C ~ 125°C versus -55°C ~ 100°C). These improvements provide design margin and enhanced reliability without introducing compatibility issues.

Regulatory Compliance: Both components carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining compliance with export control and tariff requirements.

Frequently Asked Questions (FAQ)

Q: Can the TLP620M(E) be used as a direct replacement for the TLP626(FUJI,F) in existing designs?

A: Yes. Both components share the same 4-DIP package footprint, isolation voltage, channel configuration, and output current rating. No PCB modifications are required for substitution.

Q: What are the key differences between these two optoisolators?

A: The primary differences are product status and performance characteristics. The TLP620M(E) is an active product with improved Vce saturation (300mV versus 400mV), higher maximum output voltage (80V versus 55V), and extended temperature range (-55°C ~ 125°C versus -55°C ~ 100°C).

Q: Does the higher maximum output voltage of the TLP620M(E) create compatibility issues?

A: No. A higher maximum output voltage rating indicates the substitute can handle higher voltage levels without degradation. This provides additional design margin and does not create incompatibility with circuits designed for the original 55V specification.

Q: Is the extended operating temperature range of the TLP620M(E) a concern?

A: No. The extended range (-55°C ~ 125°C versus -55°C ~ 100°C) provides additional operational capability. Applications operating within the original temperature range experience no adverse effects.

Q: Are there any package or pinout differences between these components?

A: No. Both components use identical 4-DIP (0.300", 7.62mm) through-hole packages with the same pinout configuration. Socket and PCB compatibility is maintained.

Q: What is the supply status of the TLP626(FUJI,F)?

A: The TLP626(FUJI,F) is classified as obsolete. The TLP620M(E) is an active product with ongoing manufacturing support, providing long-term supply chain stability.

Q: Do both components accept the same input signal types?

A: Yes. Both the TLP626(FUJI,F) and TLP620M(E) accept AC and DC input signals, maintaining full functional compatibility.
