1. M3933/30-21S Substitution Conclusion From the perspective of core electrical and mechanical parameters, the M3933/30-21S is a fully viable direct replacement for the original part. Its key frequency range (DC-32 GHz) is notably superior to the original part's DC-18 GHz specification. This part not only covers the entire operational bandwidth of the original but also provides additional capability to support higher frequency applications, such as millimeter-wave front-ends, resulting in superior performance metrics. With all other critical parameters (10dB attenuation, 2W power handling, 50Ω impedance, SMA interface) being identical, this part constitutes a performance-upward compatible, drop-in replacement. The substitution feasibility is high and may offer additional frequency band margin for the system.

2. 32AS102-K10S3 Substitution Conclusion The 32AS102-K10S3 is a complete technical parameter match for the original part and can serve as a direct substitute. All its core specifications—10dB attenuation, DC-18 GHz frequency range, 2W power rating, 50Ω impedance—as well as the physical interface (SMA In-Line Module) are identical to the original part LCAT1005-10, with no performance deviation. The two parts are electrically and mechanically interchangeable, making the 32AS102-K10S3 a standard, equivalent, and parametrically identical substitute. Disregarding brand preference and supply chain considerations, this part offers the highest degree of feasibility and directness for replacement.
