1. SA6S5W-06 Substitution Conclusion
Not feasible, or only viable under strictly limited conditions. The SA6S5W-06 is identical to the original FMAT7623-6 in attenuation value, power rating, and connector interface. However, its core difference lies in its frequency range, which is limited to 0-6 GHz—significantly lower than the original's 0-18 GHz. If your circuit operates above 6 GHz (e.g., in common microwave bands such as C, X, or Ku), this part will introduce insertion loss and mismatch substantially higher than the design values. This will lead to severe signal degradation, degraded system performance, or even failure. Therefore, it generally cannot serve as a direct substitute.
2. FMAT7460-6 Substitution Conclusion
Conditionally feasible, requiring evaluation based on the actual application frequency. The FMAT7460-6 matches the original FMAT7623-6 in attenuation value, power rating, impedance, and connector interface. Its difference is a maximum frequency of 12.4 GHz, falling short of the original's 18 GHz. Within the 0-12.4 GHz range (covering L, S, C, X, and part of the Ku band), it can serve as a direct, performance-equivalent replacement. However, if your application involves frequencies between 12.4 GHz and 18 GHz (such as the upper Ku band or K band), its performance will degrade and it is not suitable. The substitution decision entirely depends on whether the system's maximum operating frequency is within 12.4 GHz.
