1. SA18SS-03 Substitution Conclusion
The SA18SS-03 is identical to the original FMAT1010 in key parameters including core attenuation, power handling, and impedance. Its operational frequency range (0–18 GHz) fully covers and significantly exceeds the original part's 0–6 GHz, making it a high-performance substitute from an electrical performance perspective. The critical distinction lies in its interface type: the description "SSMA" indicates the use of a super-subminiature connector. This is physically and mechanically incompatible with the original part's standard SMA interface, preventing direct plug-and-play mating. An adapter or replacement cable would be required. If modification of the connection interface is acceptable, it is an electrically superior alternative. If an identical interface is mandatory, it is not a direct substitute.
2. FMAT7467-3 Substitution Conclusion
The FMAT7467-3 matches the original part in core specifications such as attenuation, power, and impedance. Its frequency range (0–12 GHz) also fully covers the original's 0–6 GHz, meeting all electrical requirements. However, its configuration is described as "JACK-PLUG" (female-male), which is the reverse of the original FMAT1010's "PLUG-JACK" (male-female) configuration. The connector gender sequence is inverted. Direct substitution in a system would therefore prevent mating with existing cables or ports. Despite compliant electrical parameters, the mechanical interface gender incompatibility precludes its use as a drop-in replacement.
