Original Part
Alternative Part
1. FMAT7467-6 Substitution Conclusion
The FMAT7467-6 matches the original part SA18SS-06 in key parameters such as attenuation, power handling, and impedance. However, its frequency range (0–12 GHz) is narrower than that of the original part (0–18 GHz). Additionally, the connector type has been changed from SSMA (external thread compatible with SSMA) to standard SMA. Note that mechanical compatibility between SSMA and SMA may be limited due to differences in gender configuration.
If the application operates below 12 GHz and the mechanical interface compatibility is acceptable (or can be resolved with an adapter), the FMAT7467-6 can serve as a substitute. For high‑frequency applications between 12–18 GHz, its performance may not meet specifications. Furthermore, the connector mismatch could lead to reliability issues or impedance discontinuities.
2. FMAT1012 Substitution Conclusion
The FMAT1012 also aligns with the original part in attenuation, power rating, and impedance. However, its frequency range (0–6 GHz) is significantly lower than the original (0–18 GHz), and the connector has similarly been changed to standard SMA (mechanical compatibility with the original SSMA interface must also be verified).
This substitute is only suitable for low‑frequency applications (≤6 GHz) and cannot cover the high‑frequency band of the original part. If the system operates above 6 GHz, substitution with the FMAT1012 may result in abnormal signal attenuation or functional failure. Moreover, the connector difference could introduce additional reflection loss or connection instability.
