1. SA6N5W-03 Substitution Conclusion
The SA6N5W-03 cannot serve as a full drop-in replacement for the original FMAT7624-3. The core discrepancy lies in its operational frequency range, which is limited to 0 Hz to 6 GHz, whereas the original part covers up to 18 GHz. In the high-frequency band from 6 GHz to 18 GHz, the SA6N5W-03 will either fail to function or exhibit severe degradation in key performance parameters such as attenuation and VSWR. This could lead to signal distortion or degraded system performance. Substitution should only be considered if the application is definitively confined to frequencies below 6 GHz; otherwise, it is not a viable alternative.
2. SA18N5WA-03 Substitution Conclusion
The SA18N5WA-03 is a fully acceptable electrical substitute for the original FMAT7624-3. All critical specifications are identical: attenuation (3 dB), frequency range (0–18 GHz), rated power (5W), and impedance (50Ω). The connector types are also the same. This indicates functional equivalence in core RF performance areas including bandwidth, power handling, and impedance matching, allowing for direct replacement without impacting system RF performance. When substituting, it is only necessary to verify that its physical dimensions, weight, and other mechanical specifications are compatible with the installation requirements.
