1. SA6S10W-30 Substitution Conclusion Direct substitution is not recommended. While this part matches the original (FMAT7463-30) in attenuation value, power rating, impedance, and connector interface, its maximum operating frequency is only 6 GHz, which is significantly lower than the original's 12.4 GHz. When operating within the 6 GHz to 12.4 GHz high-frequency range, the SA6S10W-30 may suffer severe degradation or even failure in attenuation accuracy, impedance matching, and power handling capability. Therefore, it is only suitable for low-frequency applications not exceeding 6 GHz and cannot serve as a full-band equivalent replacement.

2. FMAT7626-30 Substitution Conclusion This part can serve as an ideal substitute. It fully matches the original in all key parameters (30 dB attenuation, 10 W power rating, 50 Ω impedance, SMA connectors). Moreover, its operating frequency range (0 Hz to 18 GHz) completely covers and exceeds the original's upper limit of 12.4 GHz. The FMAT7626-30 maintains its specified performance across the entire operational bandwidth of the original unit, while offering additional margin for wider bandwidth applications and potential higher-frequency expansion. It is electrically and mechanically compatible for a direct drop-in replacement.
