1. FMAT7626-10 Substitution Conclusion The FMAT7626-10 is fully aligned with the original part FMAT7463-10 in key parameters—attenuation (10 dB), impedance (50 Ω), power handling (10 W), and package type—thus meeting the fundamental requirements for direct substitution. The primary difference lies in the frequency range: the FMAT7626-10 supports 0–18 GHz, whereas the original part is limited to 0–12.4 GHz. The FMAT7626-10 offers extended operation up to 18 GHz. If the original application operates at or below 12.4 GHz, substitution poses no performance risk and may even improve system bandwidth margin. However, if the original design specifically requires suppression or has compatibility constraints above 12.4 GHz, the actual requirements should be verified. In summary, for typical RF signal chains, the FMAT7626-10 can serve as a compatible replacement for the FMAT7463-10, with its wider bandwidth potentially enabling broader application flexibility.
