Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISQ202G are identified based on strict equivalence across all critical electrical and mechanical parameters. The substitution criteria include:

• Isolation voltage rating: 5300Vrms
• Current transfer ratio range: 125% to 250% @ 10mA
• Output type: Transistor
• Maximum output voltage: 70V
• Maximum output current per channel: 50mA
• Vce saturation: 400mV maximum
• Operating temperature range: -25°C to 100°C
• Package type: 16-DIP through-hole
• Compliance certifications: ROHS3 Compliant

Parts meeting all these parameters are classified as parametric equivalents and may be used as direct substitutes without circuit redesign.

The ISQ202G currently has 1053 units in stock, while the ISQ202XG has 866 units available.

Frequently Asked Questions (FAQ)

Q: Can ISQ202XG replace ISQ202G in existing designs? A: Yes. The ISQ202XG meets all electrical and mechanical specifications of the ISQ202G, including isolation voltage, current transfer ratio, output characteristics, and package dimensions. Direct substitution is possible without circuit modification.

Q: Are there any differences in compliance or certifications? A: No. Both parts carry identical RoHS3 compliance status and REACH Unaffected designation. Both are rated for the same operating temperature range and moisture sensitivity level.

Q: What determines compatibility between these optoisolators? A: Compatibility is determined by matching isolation voltage (5300Vrms), current transfer ratio range (125-250% @ 10mA), output type (transistor), maximum output voltage (70V), maximum output current (50mA), saturation voltage (400mV), operating temperature range (-25°C to 100°C), and package type (16-DIP through-hole).

Q: Are there any package or pinout differences? A: No. Both parts use identical 16-DIP (0.400", 10.16mm) through-hole packaging with the same pinout configuration.

Q: Which part should be selected based on availability? A: Selection may be based on inventory status. The ISQ202G has higher current stock levels (1053 units) compared to the ISQ202XG (866 units). Both parts maintain active production status.
