B82721S0562A030 is the strongest kept candidate by current and DCR, but it still needs footprint, pinout and impedance review.
Best Alternatives to ACM4520-901-2P-t000
ACM4520-901-2P-t000 replacements require caution because no supplied candidate proves the same 4-pin SMD footprint, pinout and 900Ω impedance.
