1. SA6-10 Substitution Conclusion Substitution is not recommended. While its attenuation value, power handling, impedance, and connector type are identical to the original part, the key technical deviation lies in its operational frequency range, which is limited to 0–6 GHz—significantly lower than the original part’s 0–18 GHz range. When used in applications above 6 GHz (such as C‑, X‑, or Ku‑band), the performance of this attenuator in terms of attenuation accuracy and VSWR cannot be guaranteed. This may lead to signal distortion, increased reflection, and potential damage to preceding circuitry due to impedance mismatch. Therefore, it is only suitable for low‑frequency applications and cannot meet the full‑bandwidth requirements of the original part.

2. FMAT7466‑10 Substitution Conclusion Conditional substitution—subject to evaluation based on the actual application frequency. This part matches the original part in core parameters (attenuation, power rating, impedance, and interface). The difference is its frequency range of 0–12 GHz, which falls short of the original part’s upper limit of 18 GHz. Within the 12–18 GHz range, its performance may deviate from specified values (e.g., variation in attenuation, degradation in VSWR). If the system operates at or below 12 GHz, it can serve as a drop‑in replacement with equivalent performance. However, it is not suitable for applications involving the 12–18 GHz band.
