1. AT-106V Substitution Conclusion
The AT-106V can partially substitute the M3933/30-13S, with its key limitation being a frequency range of only 0 Hz to 18 GHz, compared to the original part’s support up to 32 GHz. The AT-106V cannot be used in any applications requiring operation between 18 GHz and 32 GHz, such as certain millimeter-wave communications or high‑end test systems. For frequencies below 18 GHz, its attenuation, power handling, and interface configuration are consistent with the original part, allowing direct substitution. However, note that the manufacturer changes from Amphenol SV Microwave to Hirose, which may introduce slight variations in RF performance (e.g., VSWR, temperature stability) or mechanical specifications. It is recommended to verify performance within the actual frequency band before implementation.
2. M3933/25‑32S Substitution Conclusion
The M3933/25‑32S can be considered a same‑brand downgrade alternative to the M3933/30‑13S within a limited frequency range, with its upper frequency limit also capped at 18 GHz—significantly lower than the original part’s 32 GHz. This part is only suitable for applications within the Ku‑band and below, and cannot support system requirements in the Ka‑band or higher frequency ranges. Aside from the frequency limitation, both parts share identical attenuation, power rating, impedance, and package form, and are manufactured by the same supplier (Amphenol SV Microwave). Therefore, they exhibit high electrical and mechanical compatibility up to 18 GHz and can be directly interchanged. However, it is essential to strictly confirm that the system’s maximum operating frequency does not exceed 18 GHz; otherwise, performance degradation or even damage may occur.
