Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IS204G is determined by strict equivalence across the following critical parameters:

• Isolation Voltage: 5300Vrms (exact match required)
• Number of Channels: 1 (exact match required)
• Current Transfer Ratio Range: 200% to 400% @ 10mA (exact match required)
• Output Type: Transistor (exact match required)
• Maximum Output Voltage: 70V (exact match required)
• Maximum Output Current: 50mA (exact match required)
• Package Configuration: 6-DIP (0.400", 10.16mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -25°C ~ 100°C (exact match required)

Parts meeting all these criteria are classified as parametric equivalents and may be substituted in applications where the IS204G is specified.

Parameter Comparison

Engineering Selection Recommendations

The IS204XG is a parametric equivalent to the IS204G. Both components are manufactured by Isocom Components 2004 LTD within the IS20 series and share identical electrical and mechanical specifications. Both parts maintain Active product status, carry ROHS3 compliance certification, and are REACH unaffected. Selection between these parts may be based on inventory availability and lead time considerations, as all technical parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can IS204XG replace IS204G in existing designs? A: Yes. The IS204XG meets all electrical and mechanical parameter requirements specified for the IS204G, including isolation voltage, current transfer ratio, output characteristics, and package configuration.

Q: Are there any differences in compliance or regulatory status? A: No. Both parts carry identical RoHS3 compliance, REACH unaffected status, and Moisture Sensitivity Level 1 (Unlimited) designation.

Q: What determines substitution eligibility for optoisolators in this category? A: Substitution requires exact matching of isolation voltage, channel count, current transfer ratio range, output type, maximum output voltage and current, package dimensions, mounting type, and operating temperature range.

Q: Is the 6-DIP package footprint identical between both parts? A: Yes. Both IS204G and IS204XG use the 6-DIP (0.400", 10.16mm) package with Through Hole mounting, ensuring PCB layout compatibility.

Q: Can these parts be used interchangeably in high-voltage isolation applications? A: Yes. Both parts provide 5300Vrms isolation rating and are suitable for applications requiring this isolation level.
