Frequently Asked Questions (FAQ)

Q: What determines if IS203XG can substitute for IS203G?

A: Substitution is valid when all electrical parameters match: isolation voltage (5300Vrms), current transfer ratio (225-450% @ 10mA), output voltage (70V max), output current (50mA), and saturation voltage (400mV max). Both parts must also share identical package configuration (6-DIP through-hole) and operating temperature range (-25°C to 100°C).

Q: Are there any package or pinout differences between IS203G and IS203XG?

A: No. Both components use the 6-DIP (0.400", 10.16mm) through-hole package with identical pinout and mechanical specifications.

Q: Do both parts meet the same compliance standards?

A: Yes. IS203G and IS203XG are both ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

Q: Can IS203XG be used in existing designs specified for IS203G?

A: Yes. The IS203XG is a parametric equivalent with identical electrical and mechanical specifications, making it suitable for direct substitution in applications designed for IS203G.

Q: What is the difference between these substitute parts?

A: Both parts are functionally and electrically identical. Differences exist only in manufacturer part number designation and inventory availability.
