1. FMAT1010 Substitution Conclusion
Direct substitution is not recommended. The primary discrepancy lies in the frequency range: the original part supports DC to 32 GHz, whereas the FMAT1010 is limited to DC to 6 GHz. In frequency bands above 6 GHz—such as the common microwave C, X, Ku, and Ka bands—the FMAT1010 will either fail to operate or exhibit severely degraded performance, potentially leading to signal distortion or system failure. Substitution may only be considered if the entire system’s operating frequency is strictly confirmed to remain below 6 GHz; otherwise, significant risk is present.
2. FMAT7466-3 Substitution Conclusion
Conditional substitution is possible, subject to application frequency evaluation. The key differentiator remains the frequency range: the FMAT7466-3 supports DC to 12 GHz, which, while superior to the FMAT1010, still falls well short of the original part’s 32 GHz bandwidth. This part is not suitable for use within the 12 GHz to 32 GHz range, which includes important bands such as Ku, K, and Ka. If the maximum operating frequency in your specific application—for instance, many point-to-point radio links or certain radar bands—does not exceed 12 GHz, and microwave performance parameters such as attenuation accuracy and VSWR have been verified at 12 GHz, then the FMAT7466-3 can serve as a cost-reducing or availability-improving alternative. Otherwise, substitution is not advised.
