Engineering Selection Recommendations

Both IS660G and IS660XG are active production components with full compliance to ROHS3 and REACH regulations. Selection between these parts should be based on availability and supply chain considerations. The IS660XG currently has 992 units in stock compared to 842 units for the IS660G. Both components are suitable for applications requiring high-voltage isolation in 6-DIP through-hole configurations. No performance differentiation exists between these parts based on provided specifications.

Frequently Asked Questions (FAQ)

Q: Can IS660XG be used as a direct replacement for IS660G? A: Yes. The IS660XG is a parametric equivalent with identical electrical specifications, output characteristics, isolation voltage, current ratings, and package form factor. Direct substitution is supported without circuit modification.

Q: Are there any differences in compliance or certifications between IS660G and IS660XG? A: No. Both parts carry identical ROHS3 compliance status and REACH Unaffected designation. Moisture sensitivity level is equivalent at MSL 1 (Unlimited).

Q: What determines the substitution relationship between these parts? A: Substitution is based on matching all critical parameters: isolation voltage (5300Vrms), current transfer ratio (1000% @ 1mA), output type (Darlington), maximum output voltage (200V), output current (150mA), saturation voltage (1.2V), operating temperature range (-25°C ~ 100°C), and package specifications (6-DIP through-hole).

Q: Are there any package or pinout differences? A: No. Both parts use identical 6-DIP packaging with 0.400" (10.16mm) spacing and through-hole mounting technology.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection may be based on current inventory availability or supplier preference, as both maintain active production status with equivalent performance characteristics.
