Key Parameters

Substitute Part Grouping Explanation

Substitution of the ISP620-1G is determined by strict equivalence across the following critical parameters:

• Isolation voltage rating: 5300Vrms
• Number of channels: 1
• Output configuration: Transistor output
• Current transfer ratio range: 50% to 600% @ 5mA
• Maximum output voltage: 55V
• Maximum output current per channel: 50mA
• Package type: 4-DIP through-hole
• Operating temperature range: -30°C to 100°C
• Compliance certifications: ROHS3, REACH Unaffected

The ISP620-1XG meets all these criteria and is classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both ISP620-1G and ISP620-1XG are active production parts from the same manufacturer with identical electrical specifications and mechanical packaging. Selection between these parts is based on inventory availability and supply chain requirements rather than technical performance differences. Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The 4-DIP through-hole package is suitable for standard PCB assembly processes without design modification.

Frequently Asked Questions (FAQ)

Q: Can ISP620-1XG replace ISP620-1G in existing designs? A: Yes. The ISP620-1XG is a parametric equivalent with identical electrical characteristics, isolation voltage, output specifications, and 4-DIP package configuration. No circuit modifications are required.

Q: Are there any differences in compliance or certifications? A: No. Both parts carry identical ROHS3 compliance and REACH unaffected status. Regulatory requirements are met by either part.

Q: What determines substitution eligibility for optoisolators in this series? A: Substitution is valid when isolation voltage, channel count, output type, current transfer ratio range, maximum output voltage and current, package type, and operating temperature range are identical. All these parameters match between ISP620-1G and ISP620-1XG.

Q: Is the 4-DIP package compatible with automated assembly? A: Yes. The 4-DIP through-hole package is standard for automated insertion equipment and does not require special handling or modified assembly processes.

Q: Can these parts be used interchangeably in AC and DC input applications? A: Yes. Both ISP620-1G and ISP620-1XG support AC and DC input types with identical specifications for both modes of operation.
