1. FMAT7461-30 Substitution Conclusion Substitution is feasible but carries the risk of limited frequency range. The FMAT7461-30 has an upper operating frequency limit of 12.4 GHz, which is significantly lower than the original part’s 18 GHz. If the system operates between 12.4 GHz and 18 GHz, this substitute part will either fail to function or exhibit severe performance degradation—such as failing to meet specifications for attenuation value, VSWR, and other key parameters. Within the 12.4 GHz and below range, both parts share identical attenuation, power handling capability, and connector type, allowing for direct replacement.

2. SA6N5WA-30 Substitution Conclusion Substitution is only viable for low-frequency applications due to severe frequency compatibility limitations. The SA6N5WA-30 has a maximum frequency of only 6 GHz, far below the original part’s 18 GHz. This critical restriction means it can only be used in systems operating at or below 6 GHz; beyond this range, the device will be completely ineffective. Within the 6 GHz band, its 30 dB attenuation, 5 W power rating, and N-type connector match the original specifications. However, this substitution eliminates the system’s high-frequency capability and substantially narrows its applicable range.
