1. SA26B-08 Substitution Conclusion The SA26B-08 can fully replace the original part LCAT1006-08. The key difference is its extended frequency range of 0 Hz to 26 GHz, which exceeds the original part’s upper limit of 18 GHz. The SA26B-08 maintains the specified attenuation accuracy and performance even within the 18 GHz to 26 GHz band, making it suitable for higher-frequency RF systems. It fully covers the operational range of the original part and represents a direct performance upgrade.

2. FMAT7466-8 Substitution Conclusion The FMAT7466-8 can substitute for the original part LCAT1006-08 under specific conditions, but with a critical limitation. Its frequency range is limited to 0 Hz to 12 GHz, which is lower than the original part’s 18 GHz. If the application frequency exceeds 12 GHz—such as in Ku-band or certain radar/communication systems—this attenuator may introduce additional insertion loss or performance degradation. Therefore, it is only suitable for applications where the operating frequency does not exceed 12 GHz, constituting a downgraded substitution.
