1. SA26B-09 Substitution Conclusion
The SA26B-09 can serve as a full and direct replacement for the original part number FMAT7620-9. Both devices are identical in their core electrical parameters (9 dB attenuation, 2W power handling, 50Ω impedance) and mechanical package (SMA In-Line Module). The key difference is that the SA26B-09 offers an extended frequency range of 0-26 GHz, compared to the original part's 0-18 GHz. The SA26B-09 maintains its specified attenuation accuracy and performance up to 26 GHz, demonstrating superior high-frequency characteristics and wider bandwidth. For applications below 18 GHz, it provides a direct drop-in replacement with additional performance margin. Therefore, the substitution is highly feasible and typically constitutes a performance upgrade.
2. SA18E-09 Substitution Conclusion
The SA18E-09 is a fully compatible replacement for the original FMAT7620-9. All critical technical specifications are identical, including attenuation (9 dB), frequency range (0-18 GHz), power handling (2W), impedance (50Ω), and package type (SMA In-Line Module). Any differences are likely limited to the part numbering scheme, internal construction, or manufacturing process iterations, none of which affect electrical or mechanical compatibility. The SA18E-09 is a direct performance equivalent to the original part, with no concerns regarding frequency response or power matching. This represents the highest feasibility for substitution and is classified as a direct replacement type.
