1. SA6N5WA-30 Substitution Conclusion The SA6N5WA-30 is fully compatible with the original FMAT7461-30 in terms of attenuation value (30 dB), power rating (5 W), impedance (50 Ω), and connector type (N‑type inline module). However, its frequency range is limited to 0 Hz–6 GHz, whereas the original part supports 0 Hz–12.4 GHz. In applications where the operating frequency exceeds 6 GHz (e.g., C‑band and higher microwave systems), this part will introduce additional insertion loss or reflection due to insufficient bandwidth, degrading signal integrity. Therefore, it is only suitable for scenarios where the operating frequency is ≤6 GHz and cannot be directly substituted in high‑frequency applications.

2. SA3N5W-30 Substitution Conclusion The SA3N5W-30 also matches the original part in attenuation, power, impedance, and interface specifications, but its frequency range is further reduced to 0 Hz–3 GHz. This limitation restricts its use to low‑frequency or mid‑low‑frequency bands (such as UHF and portions of S‑band). In a wideband system originally designed for 12.4 GHz, this part would significantly constrain system bandwidth and may cause high‑frequency signal distortion. Consequently, it is only appropriate for applications with frequency requirements ≤3 GHz and cannot cover the full‑frequency‑range applications of the original part.
