1. SA6S10W-30 Substitution Conclusion
The SA6S10W-30 matches the original part FMAT7626-30 in key parameters including attenuation (30 dB), power rating (10 W), and impedance (50 Ω). However, its frequency range is limited to DC–6 GHz, which is significantly narrower than the original’s DC–18 GHz. The SA6S10W-30 is only suitable for low‑frequency applications (e.g., communication or test systems below 6 GHz). If substituted into higher‑frequency circuits (such as microwave or millimeter‑wave systems), it may exhibit unstable attenuation performance, increased insertion loss, or thermal damage due to overheating. Therefore, substitution feasibility depends entirely on whether the actual operating frequency remains within 6 GHz; beyond this range, the substitution is not viable.
2. FMAT7463-30 Substitution Conclusion
The FMAT7463-30 aligns with the original FMAT7626-30 in attenuation (30 dB), power rating (10 W), and impedance (50 Ω). Its frequency range, however, is DC–12.4 GHz, which is narrower than the original’s DC–18 GHz. This part can cover mid‑ to high‑frequency applications (e.g., RF links or instrument calibration up to 12.4 GHz). If used at higher frequencies (such as 18 GHz radar or satellite systems), insufficient frequency response may lead to signal distortion, reduced attenuation accuracy, or bandwidth limitations. Hence, substitution feasibility hinges on whether the system’s maximum operating frequency does not exceed 12.4 GHz. Within this limit, the part can be safely substituted; otherwise, its use is not recommended.
