1. FMAT7461-10 Substitution Conclusion Given that the core electrical parameters—attenuation (10 dB), power rating (5 W), impedance (50 Ω), and connector type—are fully identical, the FMAT7461-10 can serve as a replacement for the original part FMAT7624-10, with one critical limitation: its maximum operating frequency is 12.4 GHz, which is lower than the original part’s 18 GHz. The substitute can only be safely and reliably applied in systems or links where the operating frequency does not exceed 12.4 GHz. If the original application involves the frequency range between 12.4 GHz and 18 GHz, substitution will lead to loss of signal attenuation functionality or degraded performance, and is therefore not feasible. Under the condition that the system’s maximum operating frequency is confirmed to be ≤12.4 GHz, direct replacement is permissible; otherwise, substitution is not recommended.
