Original Part
General Purpose Digital Isolator 3750Vrms 1 Channel 150Mbps 35kV/µs CMTI 8-SOIC (0.154", 3.90mm Width)
Alternative Part
General Purpose Digital Isolator 3000Vrms 1 Channel 100Mbps 85kV/µs CMTI 8-SOIC (0.154", 3.90mm Width)
General Purpose Digital Isolator 3000Vrms 1 Channel 100Mbps 85kV/µs CMTI 8-SOIC (0.154", 3.90mm Width)
1. ISO7710FDR Substitution Conclusion
The ISO7710FDR can serve as a replacement for the original part provided that the package is compatible; however, careful evaluation under specific application conditions is required. Key differences include: isolation voltage is reduced from 3750 Vrms to 3000 Vrms, which may affect industrial or medical applications demanding high isolation; data rate drops from 150 Mbps to 100 Mbps, limiting high‑speed signal transmission capability. On the other hand, the CMTI is improved from 35 kV/µs to 85 kV/µs, significantly enhancing noise immunity and making the device more suitable for high‑noise environments such as motor drives. The supply voltage range is slightly widened (2.25 V–5.5 V), offering broader compatibility, though low‑voltage end compatibility should be verified.
2. ISO7710D Substitution Conclusion
The ISO7710D shares identical electrical parameters with the ISO7710FDR, leading to the same substitution conclusion. Both devices belong to the same TI product family, differing only in packaging or ordering codes (e.g., tape‑and‑reel vs. tube), with no variation in electrical characteristics or reliability. In applications where the ISO7710FDR is deemed acceptable, the ISO7710D can be used as a direct drop‑in replacement, provided that supply‑chain availability and mechanical compatibility with PCB layout are taken into account.
