1. FMAT7461-30 Substitution Conclusion The FMAT7461-30 can fully replace the SA3N5W-30, as both share identical core parameters: 30 dB attenuation, 5 W power handling, 50 Ω impedance, and connector type. The key difference lies in the frequency range: the FMAT7461-30 extends to 12.4 GHz, significantly higher than the original part’s 3 GHz. This gives it superior broadband performance in high‑frequency applications such as microwave communications and radar systems. For systems originally operating below 3 GHz, this difference does not affect basic functionality and instead provides additional frequency margin.

2. SA6N5WA-30 Substitution Conclusion The SA6N5WA-30 is also a viable substitute for the SA3N5W-30, with matching key specifications: 30 dB attenuation, 5 W power, 50 Ω impedance, and N‑type connectors. The main variation is its frequency range, which is rated up to 6 GHz—higher than the original 3 GHz but lower than the FMAT7461-30’s 12.4 GHz. This makes it suitable for mid‑to‑high frequency applications such as WLAN and intermediate RF links. It can be directly substituted in systems originally requiring ≤3 GHz operation, offering wider frequency adaptability. However, if future system upgrades demand operation above 6 GHz, this substitute may become limiting.
