All substitute parts listed below meet these criteria without deviation.

Parameter Comparison

Engineering Selection Recommendations

All three parts—TLP620-4G, TLP620-4XG, and ISP620-4XG—are functionally equivalent optoisolators with identical electrical and mechanical specifications. Selection between these parts is based on the following factors:

Product Availability: ISP620-4XG has the highest inventory level at 1197 units, followed by TLP620-4XG at 986 units, and TLP620-4G at 868 units. For applications requiring immediate procurement or high-volume orders, inventory availability may influence part selection.

Series Designation: TLP620-4G and TLP620-4XG belong to the TLP620-4 series, while ISP620-4XG belongs to the ISP620-4 series. Both series are manufactured by Isocom Components 2004 LTD and meet identical performance criteria.

Compliance Certification: All three parts are ROHS3 compliant and carry MSL rating 1 (Unlimited), making them suitable for regulated industries and applications with stringent environmental requirements.

Active Production Status: All parts maintain active production status, ensuring long-term availability and supply chain stability for ongoing production requirements.

For direct pin-for-pin replacement in existing designs, any of these three parts can be substituted without circuit modification or re-qualification.

Frequently Asked Questions (FAQ)
