1. FMAT7466-8 Substitution Conclusion The FMAT7466-8 matches the original AT-108V part in all key specifications, including attenuation, power handling, impedance, and connector interface. However, its operational frequency range (0–12 GHz) is significantly narrower than the original's 0–18 GHz range. Therefore, if your application operates at or below 12 GHz, the FMAT7466-8 can serve as a direct drop-in replacement. For applications requiring operation between 12 GHz and 18 GHz, this part is unsuitable due to the performance mismatch, and substitution is not feasible.

2. FMAT7467-8 Substitution Conclusion The FMAT7467-8 shares identical technical parameters with the FMAT7466-8. Its key deviation from the original AT-108V also lies in the frequency range (0–12 GHz versus 0–18 GHz). Consequently, the substitution feasibility is the same as for the FMAT7466-8: it is a valid replacement only for full-band applications up to 12 GHz and is not qualified for use in higher-frequency scenarios. Minor descriptive differences (e.g., "SS," likely referring to housing material) typically do not affect primary electrical performance.
