1. 53AS105-K30N3 Substitution Conclusion
In terms of core parameters, the 53AS105-K30N3 is identical to the original part FMAT7624-30 in attenuation value, power rating, impedance, and connector interface, providing a fundamental basis for substitution. The critical difference lies in its upper operating frequency limit of 10 GHz, whereas the original part supports up to 18 GHz. Consequently, if your application or system operates above 10 GHz, using this part will result in excessive signal attenuation or even loss, failing to meet high-frequency performance requirements. Therefore, it is only suitable for applications where the operating frequency is ≤10 GHz and is not a viable substitute otherwise.
2. SA18N5WA-30 Substitution Conclusion
The SA18N5WA-30 and the original part FMAT7624-30 are products from the same manufacturer (Fairview Microwave). Their nominal key technical parameters—including 30 dB attenuation, 0-18 GHz frequency range, 5W power rating, 50-ohm impedance, and N-type connector interface—are completely identical. This indicates a high degree of direct electrical and mechanical interchangeability between the two. Although the part description mentions "PLUG-JACK TYPE N 1.35," which typically refers to the specific coupling nut style (1.35 hex nut) of its N-type connector, this is one of the industry-standard formats compatible with most N-type ports. Thus, it can be considered a direct substitute in the vast majority of applications. However, for scenarios with extremely stringent mechanical compatibility requirements, it is advisable to verify the nut specification of the mating port.
