1. FMAT7466-9 Substitution Conclusion The FMAT7466-9 is technically a fully viable substitute for the original FMAT1013, as it matches the original in attenuation value, power handling, impedance, and package type. The key difference lies in its extended frequency range of 0 Hz to 12 GHz, compared to the original’s 6 GHz limit. Within the original application range (0–6 GHz), the FMAT7466-9 delivers identical electrical performance and compatibility, enabling a seamless drop-in replacement. Additionally, the wider frequency coverage allows it to support high-frequency applications up to 12 GHz, enhancing system scalability and flexibility for future upgrades with no performance degradation. However, potential trade-offs include slightly higher cost or physical dimensions—note the described "SS" stainless-steel construction and length difference (1.35″ vs. 1.22″). Mechanical compatibility should be verified prior to implementation.

2. SA26B-09 Substitution Conclusion The SA26B-09 is also technically feasible as a replacement for the original FMAT1013, with identical attenuation, power rating, impedance, and package type. Its frequency range, however, is significantly broader—extending from 0 Hz to 26 GHz, far exceeding the original’s 6 GHz capability. For applications below 6 GHz, the SA26B-09 maintains equivalent electrical characteristics and can be directly substituted without performance loss. The extended frequency coverage also makes it suitable for very high-frequency scenarios such as millimeter-wave applications, improving device versatility and future upgrade potential. This enhancement may come with increased manufacturing cost or slightly larger physical size (e.g., length 1.4″ vs. 1.22″). Cost-effectiveness and spatial compatibility should be evaluated during substitution, especially in size-constrained designs.
