Parameter Comparison

Engineering Selection Recommendations

All three parts—TLP620-2SM, TLP620-2XSM, and ISP620-2XSM—are functionally equivalent and maintain active production status. Selection between these optoisolators should be based on inventory availability and supply chain considerations:

• TLP620-2SM: 673 units in stock
• TLP620-2XSM: 791 units in stock
• ISP620-2XSM: 1059 units in stock

All parts comply with ROHS3 requirements and carry REACH Unaffected status, meeting regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

Frequently Asked Questions (FAQ)

Q: Can TLP620-2XSM and ISP620-2XSM be used as direct replacements for TLP620-2SM?

A: Yes. All three parts share identical electrical specifications, isolation voltage, current transfer ratios, timing characteristics, and mechanical packaging. They are functionally equivalent and can be substituted directly in circuit designs without modification.

Q: Are there differences in the package designation between these parts?

A: No. All three parts use the same 8-SMD, Gull Wing surface-mount package with identical pin configurations and mechanical dimensions, enabling direct PCB placement compatibility.

Q: What is the significance of the "X" designation in TLP620-2XSM?

A: The "X" designation indicates a variant within the TLP620-2 series. However, the electrical and mechanical parameters remain identical to the TLP620-2SM, maintaining full substitution compatibility.

Q: Do all three parts meet the same compliance standards?

A: Yes. All parts are ROHS3 Compliant, REACH Unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.49.8000) classifications. They meet the same regulatory and environmental requirements.

Q: Which part should be selected based on availability?

A: ISP620-2XSM offers the highest inventory level at 1059 units, followed by TLP620-2XSM at 791 units, and TLP620-2SM at 673 units. Selection should prioritize supply chain continuity and lead time requirements.

Q: Are there any thermal or operating condition differences between these parts?

A: No. All three parts operate across the identical temperature range of -30°C to 100°C with matching thermal characteristics and performance specifications.
