1. FMAT7462-3 Substitution Conclusion
The FMAT7462-3 matches the original FMAT7625-3 exactly in key parameters: attenuation (3dB), power rating (5W), impedance (50Ω), and package (TNC In-Line Module). However, its frequency range is limited to 0 Hz to 12.4 GHz, compared to the original's 0 Hz to 18 GHz. For applications where the operating frequency does not exceed 12.4 GHz (common in mid-to-low frequency bands for microwave communications or test systems), the FMAT7462-3 can be safely substituted without performance impact. If the system involves high-frequency operation between 12.4 GHz and 18 GHz (e.g., satellite communications or high-end radar applications), this part is unsuitable due to insufficient frequency coverage. Using it in such scenarios could lead to inaccurate signal attenuation or potential device damage.
2. SA18T5W-03 Substitution Conclusion
The SA18T5W-03 is identical to the original FMAT7625-3 in all critical specifications: attenuation (3dB), frequency range (0 Hz to 18 GHz), power rating (5W), impedance (50Ω), and package (TNC In-Line Module). There are no technical deviations. From a specification standpoint, the SA18T5W-03 provides a direct, fully compatible drop-in replacement suitable for all original application scenarios (e.g., broadband testing, high-frequency RF systems). No performance degradation or adaptation issues are expected. The only difference is the part number designation, making it an electrically equivalent substitute.
