1. Substitution Conclusion for 6N135S(TA)-V
The substitution is feasible and can serve as a direct replacement. The two devices are identical in all key specifications, including isolation voltage, current transfer ratio (CTR), input/output types, and primary electrical parameters. The main distinction is that the Everlight part explicitly specifies its switching time parameters (Ton/Toff 350ns/500ns), while the original manufacturer's datasheet lacks this data. In applications demanding higher dynamic performance, such as switching signal isolation, the 6N135S(TA)-V offers a clear performance guarantee. This is preferable to the unspecified parameters of the original part, providing greater certainty in the design phase.
2. Substitution Conclusion for 6N135S(TB)-V
The substitution is feasible and can serve as a direct replacement. Its characteristics are identical to the 6N135S(TA)-V, with no parametric differences between the two Everlight variants. Compared to the original part, all core static parameters are fully matched. The key difference, again, is the explicit specification of switching characteristics (Ton/Toff 350ns/500ns). Post-substitution, engineers can design or verify circuit timing based on its defined switching speed. This eliminates the uncertainty caused by the missing parameters in the original part's documentation, making the substitution both safe and more transparent from an information standpoint.
