Original Part
Alternative Part
1. AT-107V Substitution Conclusion
The AT-107V matches the original FMAT7467-7 in all key parameters—attenuation (7 dB), power rating (2 W), impedance (50 Ω), and package (SMA In‑Line Module)—while extending the frequency range to 0–18 GHz, compared to the original 0–12 GHz. This gives the AT-107V wider bandwidth coverage in high‑frequency applications. If the original system operates only below 12 GHz, the difference does not affect basic functionality and instead provides additional frequency margin and future upgrade flexibility. However, note that the manufacturer differs (Hirose Electric Co Ltd); practical implementation should verify mechanical interface compatibility and long‑term reliability to ensure a seamless drop‑in replacement. From a technical specification standpoint, the AT-107V is a viable direct substitute.
2. M3933/25-33S Substitution Conclusion
The M3933/25-33S is identical to the original FMAT7467-7 in critical metrics—attenuation, power handling, impedance, and package—but similarly improves the frequency range to 0–18 GHz versus the original 12 GHz upper limit. This part offers superior RF performance, supporting higher‑frequency signal processing and making it suitable for broader high‑frequency or wideband systems. If the original design is intended for operation below 12 GHz, substitution introduces no technical conflict and may even enhance high‑frequency stability. Due to the change in manufacturer (Amphenol SV Microwave), factors such as supply‑chain availability, cost, and mechanical footprint compatibility with the existing circuit layout should be evaluated. In summary, the M3933/25-33S is technically feasible as a replacement.
