1. SA18T5W-10 Substitution Conclusion The SA18T5W-10 is a fully qualified direct replacement for the original FMAT7625-10 part from both electrical and mechanical compatibility perspectives. Key electrical parameters—including attenuation (10 dB), impedance (50 Ω), power rating (5 W)—and the interface form (TNC In‑Line Module) are identical. The frequency range also matches, covering 0–18 GHz. Potential differences are limited to mechanical details suggested by the part number (e.g., “SS” may indicate a stainless‑steel housing) or internal construction, which typically do not affect functionality or performance in standard RF links. The substitution can be safely implemented.

2. FMAT7462-10 Substitution Conclusion The FMAT7462-10 matches the original part in attenuation, impedance, power rating, and interface form. However, its frequency range is limited to 0–12.4 GHz, which is lower than the original’s 18 GHz upper limit. If the application operates above 12.4 GHz, the FMAT7462-10 is unsuitable; forced substitution would degrade performance (e.g., increased attenuation error, higher VSWR) and could lead to damage. If the system’s maximum operating frequency is confirmed not to exceed 12.4 GHz, the FMAT7462-10 can serve as a viable alternative.
