IS852G Optoisolator Darlington Output Equivalent & Substitute Parts

Part Overview

The IS852G is a single-channel optoisolator with Darlington output manufactured by Isocom Components 2004 LTD. This 4-DIP through-hole component provides galvanic isolation up to 5300Vrms and is designed for DC input applications requiring high current transfer ratios. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance can be maintained across the same product category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the IS852G are identified based on strict electrical and mechanical parameter matching within the optoisolator Darlington output category. The substitution criteria are:

• Single-channel configuration
• Isolation voltage of 5300Vrms
• Current transfer ratio range: 1000% to 15000% @ 1mA
• Darlington output type
• Maximum output voltage of 300V
• Output current capacity of 150mA per channel
• Vce saturation maximum of 1.2V
• Operating temperature range of -30°C to 100°C
• 4-DIP through-hole package (0.400", 10.16mm)
• RoHS3 compliance
• Active product status

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

All three parts—IS852G, IS627G, and IS852XG—are direct parametric equivalents with identical electrical specifications and mechanical compatibility. Selection between these parts is based on availability and supply chain considerations rather than technical differentiation.

IS852G and IS852XG are both members of the IS852 series, while IS627G belongs to the IS627 series. Despite the series designation difference, IS627G meets all electrical and mechanical requirements for direct substitution. All three parts maintain active product status and full RoHS3 compliance, ensuring regulatory consistency across component selection.

Frequently Asked Questions (FAQ)

Q: Can IS627G be used as a direct replacement for IS852G?

A: Yes. IS627G meets all electrical parameters, isolation voltage, current transfer ratio specifications, output characteristics, and package requirements. The series designation difference does not affect functional compatibility.

Q: Are there any differences in the 4-DIP package between these parts?

A: No. All three parts use identical 4-DIP through-hole packaging (0.400", 10.16mm) with the same pin configuration and mounting requirements.

Q: Do all substitute parts have the same compliance certifications?

A: Yes. IS852G, IS627G, and IS852XG are all RoHS3 compliant with REACH unaffected status and EAR99 export classification.

Q: What is the basis for substitution between IS852G and IS852XG?

A: Both parts are from the IS852 series with identical electrical specifications, isolation voltage, current transfer ratios, output voltage and current ratings, saturation characteristics, and operating temperature range. They are mechanically and electrically interchangeable.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. All three parts share the same 4-DIP through-hole package footprint and pin configuration, allowing direct PCB-level substitution without layout modifications.
