Original Part
Alternative Part
1. SA18SS-06 Substitution Conclusion
The SA18SS-06 is electrically identical to the original part FMAT1011 in key parameters (6 dB attenuation, 2 W power handling, 50 Ω impedance), but offers an extended frequency range of 0–18 GHz compared to the original’s 0–6 GHz, enabling support for higher-frequency applications. The critical difference lies in the connector type: the SA18SS-06 uses an SSMA interface (specified as SSMA SS 1.6), whereas the original part employs an SMA connector. This mechanical incompatibility prevents direct plug‑and‑play replacement. Forced substitution without an adapter would result in physical connection failure. Therefore, the SA18SS‑06 can only serve as a performance‑enhanced alternative if the host system interface permits or a suitable adapter is available; otherwise, substitution is not feasible.
2. FMAT7467‑6 Substitution Conclusion
The FMAT7467‑6 matches the original FMAT1011 in core specifications—attenuation, power rating, and impedance—while extending the frequency range to 0–12 GHz (versus 0–6 GHz for the original). Moreover, its package and connector are both SMA type (specified as SMA 1.35), ensuring full mechanical compatibility. The FMAT7467‑6 can be directly swapped with the original part without any additional adaptation. It fully covers all application scenarios of the original (e.g., systems up to 6 GHz) and provides additional headroom for future higher‑frequency use. The FMAT7467‑6 is a viable and recommended upgrade substitute.
