1. SA6H-01 Substitution Conclusion The SA6H-01 has limited feasibility as a substitute, primarily due to its frequency range (0–6 GHz) being significantly narrower than the original part’s upper limit of 18 GHz. Within the 6–18 GHz band, this attenuator cannot guarantee the specified attenuation accuracy and impedance matching, which may lead to increased signal distortion or reflection. Therefore, it is only suitable for low-frequency applications (such as certain wireless communications or testing). Direct substitution is not recommended if the system operates above 6 GHz.

2. FMAT7467-1 Substitution Conclusion The FMAT7467-1 is conditionally viable as a substitute. Its frequency range (0–12 GHz), although still lower than the original part’s 18 GHz, covers most common RF application bands. If the actual system’s maximum operating frequency is ≤12 GHz and the requirements for attenuation flatness are not extremely stringent, this part can serve as a temporary or downgraded replacement. However, for scenarios requiring full-band 0–18 GHz performance (such as high-frequency testing, satellite communications, etc.), substitution carries risk due to unverified performance in the 12–18 GHz range.
