1. FMAT7624-30 Substitution Conclusion The FMAT7624-30 can fully replace the original part SA6N5WA-30. Both attenuators share identical key specifications—30 dB attenuation, 5 W power handling, 50 Ω impedance, N‑type connectors, and module form factor—ensuring complete electrical and mechanical compatibility. The difference lies in the frequency range: the original part covers 0–6 GHz, whereas the FMAT7624‑30 extends to 0–18 GHz. The newer part offers broader applicability at higher frequencies and, due to its wider bandwidth design, typically provides improved frequency‑response flatness and stability at frequencies below 6 GHz. Therefore, the substitution will not degrade performance; instead, it may enhance system margin in wideband applications.
