1. FMAT7624-2 Substitution Conclusion The FMAT7624-2 can fully replace the original part SA18N5WA-02, as both share identical key electrical parameters: 2 dB attenuation, 0 Hz to 18 GHz frequency range, 5 W power handling, 50 Ω impedance, and N‑Type In‑Line Module package. This ensures equivalent RF performance and application coverage. The only distinction lies in the connector designation within the description: the original part is noted as “PLUG‑JACK TYPE N,” which may imply a combination of plug and jack configuration, while the FMAT7624‑2 is specified as “N‑TYPE MAL,” clearly indicating an N‑type male connector. During physical interconnection, connector gender matching should be considered; however, since both are N‑type in‑line modules from the same manufacturer and share identical packaging, this difference generally does not affect electrical characteristics or basic interconnect compatibility. In most practical installations, the two parts can be used interchangeably without modification.
