IS205G Optoisolator Equivalent & Substitute Parts

Part Overview

The IS205G is an optoisolator with transistor output manufactured by Isocom Components 2004 LTD. This 6-pin DIP component provides galvanic isolation up to 5300Vrms with a single channel transistor output configuration. The part is currently in active production status with 1030 units available in stock. Substitute parts may be required due to supply constraints, regional availability, or inventory management in production environments.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IS205G is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following key areas:

Isolation voltage (5300Vrms), single channel configuration, transistor output topology, current transfer ratio minimum (100% @ 10mA), rise and fall time characteristics (2µs each), maximum output voltage (30V), output current per channel (50mA), forward voltage (1.2V typical), maximum forward current (60mA), saturation voltage (400mV maximum), operating temperature range (-55°C to 100°C), and 6-DIP through-hole package format.

All substitute parts must also maintain compliance with RoHS3, REACH, and MSL Level 1 specifications to ensure regulatory and environmental compatibility.

Parameter Comparison

Engineering Selection Recommendations

The IS205XG is a parametric equivalent substitute for the IS205G. Both parts are manufactured by Isocom Components 2004 LTD within the IS205 series and maintain identical electrical and mechanical specifications across all critical parameters.

Selection between IS205G and IS205XG is based on availability and supply chain requirements. Both parts carry active product status, ROHS3 compliance, REACH unaffected designation, and MSL Level 1 rating. The parts are pin-compatible and functionally interchangeable in 6-DIP through-hole applications requiring 5300Vrms isolation with single-channel transistor output.

Frequently Asked Questions (FAQ)

Q: Can IS205XG replace IS205G in existing designs? A: Yes. The IS205XG is a parametric equivalent with identical electrical specifications, isolation voltage, output characteristics, and 6-DIP package format. Direct substitution is supported without circuit modification.

Q: Are there differences in compliance or certifications between IS205G and IS205XG? A: No. Both parts maintain identical RoHS3 compliance, REACH unaffected status, and MSL Level 1 rating.

Q: What determines substitution eligibility for IS205 series optoisolators? A: Substitution is determined by matching isolation voltage (5300Vrms), channel count (1), output type (transistor), current transfer ratio (100% @ 10mA), timing characteristics (2µs rise/fall), output voltage rating (30V), output current (50mA), forward voltage (1.2V), saturation voltage (400mV), temperature range (-55°C to 100°C), and package format (6-DIP through-hole).

Q: Is the 6-DIP package identical between both parts? A: Yes. Both IS205G and IS205XG use the same 6-DIP (0.400", 10.16mm) through-hole package with identical pin configuration and mechanical dimensions.

Q: Can these parts be used in high-temperature applications? A: Both parts support the operating temperature range of -55°C to 100°C as specified. Applications requiring operation outside this range are not supported.
