1. AT-110V Substitution Conclusion
The AT-110V can serve as a replacement for the original part under limited conditions. The key difference lies in its frequency range (0–18 GHz), which is significantly narrower than the original part's 0–32 GHz. This device is only suitable for applications up to 18 GHz; operation above 18 GHz will result in performance degradation or failure. Additionally, the manufacturer has changed from Amphenol SV Microwave—which specializes in military-grade microwave components—to Hirose. This shift may imply unstated differences in parameters such as temperature stability under extreme conditions, phase linearity, or long-term reliability. For demanding applications such as test and measurement or aerospace/defense systems, thorough evaluation and validation are required.
2. 32AS102-K10S3 Substitution Conclusion
Similar to the AT-110V, the 32AS102-K10S3 is a conditional substitute. Its primary limitation is also the frequency range (0–18 GHz versus 0–32 GHz), which restricts its use in millimeter-wave applications (18–32 GHz). Another critical difference is the change in manufacturer to Rosenberger. While Rosenberger is well-regarded in RF connector design, its attenuator products may exhibit subtle variations in microwave performance—such as VSWR and attenuation flatness at higher frequencies—compared to the original part. For general commercial applications below 18 GHz where power handling (2W) and interface matching (SMA) are adequate, substitution is feasible. However, in broadband or high-performance RF links, it is essential to conduct actual measurements to verify that performance meets system requirements across the entire operating band.
