1. SA18E-07 Substitution Conclusion The SA18E-07 can fully replace the original part FMAT7467-7. Both devices are identical in key specifications—attenuation (7 dB), impedance (50 Ω), power rating (2 W), and package style. The most critical distinction is that the SA18E-07 offers a wider frequency range (DC‑18 GHz) compared to the original part’s DC‑12 GHz. The SA18E-07 maintains its specified attenuation accuracy and impedance matching up to 18 GHz, fully covering and exceeding the operating range of the original component. Substitution will therefore provide improved high‑frequency performance or additional margin. One note: the connector gender (Plug‑Jack) of the SA18E-07 may be opposite to that of the original part (Jack‑Plug); installation should verify mechanical compatibility.

2. SA6H-07 Substitution Conclusion The SA6H-07 is not a drop‑in replacement for the original FMAT7467-7. Although their basic parameters—attenuation, impedance, power rating, and package—are the same, the SA6H-07 has a significantly narrower frequency range (DC‑6 GHz) versus the original part’s DC‑12 GHz. If the system operates between 6 GHz and 12 GHz, using the SA6H-07 will degrade performance: attenuation may deviate from the nominal value, VSWR may increase, and signal integrity cannot be guaranteed, potentially leading to system failure. Substitution is acceptable only if the application is strictly limited to frequencies below 6 GHz; otherwise, its use must be avoided.
