IS5G Optoisolator Transistor Equivalent & Substitute Parts

Part Overview

The IS5G is an optoisolator transistor with base output manufactured by Isocom Components 2004 LTD. This 6-pin high-density transistor detector operates at 5300Vrms isolation voltage and is designed for applications requiring galvanic isolation with transistor output control. The part is currently active in production with 674 units in stock. Substitute parts are identified when identical electrical and mechanical parameters are maintained across isolation voltage, current transfer ratio, output voltage rating, channel configuration, and package specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IS5G is determined by strict equivalence across the following critical parameters:

• Voltage - Isolation: 5300Vrms
• Number of Channels: 1
• Output Type: Transistor with Base
• Current Transfer Ratio range: 50% (Min) to 400% (Max) @ 10mA
• Voltage - Output (Max): 70V
• Current - Output / Channel: 50mA
• Package / Case: 6-DIP (0.400", 10.16mm)
• Mounting Type: Through Hole

The IS5XG meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical specifications, isolation ratings, output characteristics, and physical packaging, enabling direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both IS5G and IS5XG are active production parts manufactured by Isocom Components 2004 LTD with full ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on availability and inventory requirements. The IS5XG currently has higher inventory availability (1133 units) compared to the IS5G (674 units). Both parts meet identical electrical, thermal, and mechanical specifications, making them fully interchangeable for 5300Vrms isolation applications requiring single-channel transistor output with base control in 6-DIP through-hole packages.

Frequently Asked Questions (FAQ)

Q: Can IS5XG replace IS5G in existing designs? A: Yes. Both parts are parametric equivalents with identical isolation voltage (5300Vrms), current transfer ratio (50%-400% @ 10mA), output voltage rating (70V max), output current (50mA), and 6-DIP package specifications. Direct substitution is supported without circuit modification.

Q: Are there differences in isolation performance between IS5G and IS5XG? A: No. Both parts maintain 5300Vrms isolation voltage rating and identical input/output electrical characteristics across the specified operating temperature range of -25°C to 100°C.

Q: What determines substitution eligibility for optoisolator transistors? A: Substitution requires matching isolation voltage rating, number of channels, output type (transistor with base), current transfer ratio range, maximum output voltage, maximum output current per channel, package type, and mounting configuration. All these parameters are identical between IS5G and IS5XG.

Q: Are both parts suitable for high-temperature applications? A: Both IS5G and IS5XG operate across -25°C to 100°C. Applications requiring operation beyond this range require alternative part selection.

Q: What is the significance of the 6-DIP package specification? A: The 6-DIP (0.400", 10.16mm) package ensures mechanical and electrical compatibility with standard through-hole PCB layouts. Both IS5G and IS5XG use identical package dimensions, enabling direct board-level substitution without layout modifications.
