1. SA3S5W-06 Substitution Conclusion
This part is not a reliable or direct substitute. The core discrepancy lies in its frequency range, which is limited to 0-3 GHz, whereas the original part supports 0-6 GHz. If the system operates above 3 GHz (e.g., within the 5-6 GHz C-band or Wi-Fi 5/6 bands), the SA3S5W-06's critical performance parameters—such as attenuation accuracy and VSWR—will degrade significantly or become unguaranteed. This could lead to signal distortion, system mismatch, or even potential damage. Therefore, it is only suitable for applications where the operating frequency is confirmed to remain consistently below 3 GHz.
2. FMAT7623-6 Substitution Conclusion
This part is an excellent direct substitute in terms of electrical performance. Its key advantage is an extended frequency range of 0-18 GHz, which fully covers and exceeds the original part's 0-6 GHz requirement. Across all frequencies of the original design, its attenuation accuracy, matching performance (VSWR), and power handling capability are fully ensured. Furthermore, it provides headroom for potential future system upgrades (e.g., extension into the Ku-band). Both parts are identical in attenuation value, power rating, and interface form factor. Consequently, it can be directly replaced and is expected to perform equal to or better than the Original Part.
