1. FMAT7624-2 Substitution Conclusion The FMAT7624-2 can fully replace the original part SA6N5WA-02, as their key parameters—attenuation (2 dB), power rating (5 W), impedance (50 Ω), and package (N‑type in‑line module)—are identical, ensuring equivalent electrical performance. The difference lies in the frequency range: the FMAT7624‑2 supports 0 Hz to 18 GHz, while the original part only covers 0 Hz to 6 GHz. The wider operating bandwidth of the FMAT7624‑2 not only ensures backward compatibility with all low‑frequency applications of the original part but also extends usability to higher‑frequency scenarios, such as millimeter‑wave communications or test systems, thereby improving versatility and future‑readiness. Additionally, the FMAT7624‑2 is described with “N‑TYPE MAL” (N‑type male), whereas the original part is listed as “PLUG‑JACK”; this may indicate a connector‑gender difference, though it generally does not affect mechanical compatibility for in‑line modules—simply verify interface matching during actual installation. From a technical‑specification standpoint, substitution is feasible and recommended, particularly for applications requiring higher‑frequency performance or design upgrades.
