Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TLP620SM are identified based on strict equivalence of critical electrical and mechanical parameters. The substitution criteria are:

• Single-channel optoisolator configuration
• 5300Vrms isolation voltage rating
• Current transfer ratio range: 50% to 600% @ 5mA
• Transistor output type with 55V maximum output voltage
• 50mA maximum output current per channel
• 4µs and 3µs rise and fall times
• AC and DC input capability
• 4-SMD, Gull Wing surface mount package
• Operating temperature range: -30°C to 100°C
• RoHS3 compliance and MSL Level 1 rating

All identified substitute parts maintain these parameters without deviation, ensuring functional and mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TLP620SM, TLP620XGBSM, and ISP620-1XSM—are Active status components manufactured by Isocom Components 2004 LTD with identical electrical and mechanical specifications. Selection between these parts may be based on inventory availability and supply chain considerations. All parts maintain RoHS3 compliance and MSL Level 1 rating, meeting regulatory and environmental requirements for industrial and commercial applications. The 4-SMD, Gull Wing package format ensures compatibility with standard surface mount assembly processes.

Frequently Asked Questions (FAQ)

Q: Can TLP620XGBSM or ISP620-1XSM be used as direct replacements for TLP620SM?

A: Yes. Both parts maintain identical electrical parameters including isolation voltage, current transfer ratio, output voltage and current ratings, and timing characteristics. The 4-SMD, Gull Wing package format is identical across all three parts, enabling direct PCB footprint compatibility.

Q: What are the key parameters that define substitution eligibility for this optoisolator?

A: Substitution is determined by equivalence in isolation voltage (5300Vrms), single-channel configuration, current transfer ratio range (50% to 600% @ 5mA), transistor output type, maximum output voltage (55V), maximum output current (50mA), rise and fall times (4µs and 3µs), AC/DC input capability, and 4-SMD, Gull Wing surface mount package.

Q: Are there differences in series designation between TLP620SM and ISP620-1XSM?

A: The parts belong to different series designations (TLP620 versus ISP620-1) but maintain identical electrical and mechanical parameters. Series designation does not affect functional compatibility in circuit applications.

Q: Do all substitute parts have the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -30°C to 100°C, ensuring consistent performance across environmental conditions.

Q: What is the significance of MSL Level 1 rating for these components?

A: MSL Level 1 indicates unlimited moisture sensitivity, meaning these components do not require special moisture control during storage, handling, or assembly processes.
