1. SA18S5W-03 Substitution Conclusion
From the perspective of core electrical performance and mechanical interface, the SA18S5W-03 is a fully viable substitute for the original FMAT7460-3 part. Key parameters, including attenuation value (3dB), power handling capacity (5W), characteristic impedance (50Ω), and interface configuration (SMA feed-through module), are identical between the two. The primary distinction lies in the frequency range: the SA18S5W-03 offers a significantly wider bandwidth (0-18 GHz) compared to the original part's 0-12.4 GHz. This grants the substitute broader applicability and greater performance margin in the higher frequency spectrum. Within the original operational band up to 12.4 GHz, the SA18S5W-03 enables seamless replacement without introducing any performance degradation.
2. FMAT7623-3 Substitution Conclusion
The FMAT7623-3 is functionally capable of replacing the original FMAT7460-3 part. Both share identical core specifications: 3dB attenuation, 5W power rating, 50Ω impedance, and SMA feed-through module packaging. The key difference, again, is the frequency range. The FMAT7623-3 supports 0-18 GHz, covering and exceeding the original part's 12.4 GHz upper limit. Within the original design's intended frequency band, the substitute provides equivalent attenuation performance and power handling capability. Furthermore, its wider bandwidth offers hardware compatibility for potential system frequency expansion, making it a performance-upward-compatible alternative.
