1. SA6-07 Substitution Conclusion The SA6-07 is not a fully compatible substitute for the original FMAT7620-7. The primary discrepancy lies in its operational frequency range, which is limited to 0–6 GHz, whereas the original component supports 0–18 GHz. In the high-frequency band from 6 GHz to 18 GHz, the SA6-07 will either fail to operate or exhibit severe degradation in signal attenuation performance. Consequently, it is only suitable for low-frequency applications where the operating frequency is confirmed not to exceed 6 GHz. Direct substitution in systems requiring full-band coverage carries significant risk.

2. SA18E-07 Substitution Conclusion The SA18E-07 is a fully compatible substitute for the original FMAT7620-7. Its key parameters—attenuation value (7 dB), frequency range (0–18 GHz), power handling capacity (2 W), and impedance (50 Ω)—are identical to those of the original part. Furthermore, the interface configuration is the same: an in-line SMA Plug-to-Jack module. The SA18E-07 is electrically equivalent and mechanically compatible with the original part, allowing for direct replacement without any compromise to system performance or modification to the interconnection scheme.
