Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLP630(GB-TP1,F) is determined by the following critical parameters:

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

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

Current Transfer Ratio: The substitute must support the 100% to 600% @ 5mA range to ensure consistent signal transfer characteristics.

Output Type and Switching Characteristics: The substitute must provide equivalent turn-on/turn-off times (3µs typical) and rise/fall times (2µs, 3µs typical) to maintain circuit timing performance.

Input Type: AC and DC input compatibility must be preserved.

Current and Voltage Ratings: Output current of 50mA and maximum output voltage specifications must be met or exceeded.

Operating Temperature Range: The substitute must support the -55°C to 100°C operating window or provide an extended range.

Mounting and Package: Surface mount configuration with compatible footprint dimensions is required for PCB integration.

The TLP620M(GB-TP1,E) qualifies as a substitute based on these parameters while offering active product status and enhanced specifications.

Parameter Comparison

Engineering Selection Recommendations

The TLP620M(GB-TP1,E) serves as the primary substitute for the obsolete TLP630(GB-TP1,F). Both components are manufactured by Toshiba Semiconductor and Storage and share identical isolation voltage, current transfer ratio specifications, and switching characteristics essential for optoisolator functionality.

The TLP620M(GB-TP1,E) offers the following advantages:

Active Product Status: The substitute is actively produced, ensuring long-term availability and supply chain continuity.

Enhanced Electrical Performance: The substitute provides a higher maximum output voltage rating (80V versus 55V) and lower saturation voltage (300mV versus 400mV), delivering improved performance margins in most applications.

Extended Operating Temperature Range: Support for -55°C to 125°C operation provides additional thermal margin compared to the original -55°C to 100°C range.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications, maintaining export and import compliance.

Package Consideration: The substitute uses a 4-SMD package versus the original 6-SMD package. PCB layout modification is required to accommodate the different pin configuration, though the 0.300" (7.62mm) pitch remains consistent.

Output Configuration Difference: The TLP620M(GB-TP1,E) provides standard transistor output without base connection. Applications utilizing the base output of the original device require circuit redesign to accommodate the standard transistor configuration.

Frequently Asked Questions (FAQ)

Q: Can the TLP620M(GB-TP1,E) directly replace the TLP630(GB-TP1,F) without PCB modification?

A: No. The TLP620M(GB-TP1,E) uses a 4-SMD package compared to the 6-SMD package of the original part. PCB footprint redesign is required. However, the 0.300" (7.62mm) pitch dimension is identical, simplifying layout adaptation.

Q: What is the primary difference between these two optoisolators?

A: The main functional difference is the output configuration. The TLP630(GB-TP1,F) provides transistor output with base connection, while the TLP620M(GB-TP1,E) provides standard transistor output without base access. Applications requiring base control must be redesigned.

Q: Are the isolation voltage ratings identical?

A: Yes. Both components provide 5000Vrms isolation voltage, meeting identical safety and regulatory requirements.

Q: Does the substitute support the same input and output current specifications?

A: The current transfer ratio specifications are identical (100% to 600% @ 5mA), and both support 50mA output current per channel. The substitute's maximum forward current is rated at 50mA versus the original 60mA, which is acceptable for most applications.

Q: Is the operating temperature range compatible?

A: The substitute supports an extended range (-55°C to 125°C) compared to the original (-55°C to 100°C). This provides additional thermal margin and is fully compatible with applications designed for the original temperature range.

Q: Are switching characteristics preserved?

A: Yes. Turn-on/turn-off times (3µs typical) and rise/fall times (2µs, 3µs typical) are identical between both components, ensuring equivalent circuit timing performance.

Q: What are the regulatory compliance implications?

A: Both components share identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. No compliance changes are introduced by substitution.

Q: Can the higher output voltage rating of the substitute cause compatibility issues?

A: No. The substitute's 80V maximum output rating exceeds the original 55V rating, providing improved performance margin. Applications designed for 55V operation remain fully compatible.

Q: What is the significance of the lower saturation voltage in the substitute?

A: The substitute's 300mV saturation voltage (versus 400mV in the original) represents improved switching efficiency and reduced power dissipation, providing performance enhancement without compatibility concerns.
