The FMAT7626-10 can serve as a full drop-in replacement for the original part SA6S10W-10, as both share identical key specifications including attenuation (10 dB), power handling (10 W), impedance (50 Ω), and package (SMA in-line module). The only difference lies in the frequency range: the FMAT7626-10 supports DC to 18 GHz, whereas the original part is rated only for DC to 6 GHz. With its wider bandwidth, the new part offers improved performance in higher‑frequency applications while fully covering the operational range of the original part. Therefore, substitution is fully feasible without compromising existing functionality, and may provide additional advantages in terms of cost or when extended high‑frequency capability is required.
