Offers higher current in the same package, but impedance differs significantly.
WCM4532F2SF-601T15 is a 1.5A, 600Ω common mode choke in a 4532 (1812) package. When searching for replacements, key parameters like impedance, current rating, and package size are critical for maintaining circuit performance.
Impedance vs. frequency curve must match the application's needs.
Many alternatives exist in the standard 4532 (1812) package.
No verified pin-to-pin replacement is available, but YLM4532-601T is a strong candidate requiring engineering review of the datasheet.
YLM4532-601T appears to be a strong functional alternative with closely matching key specifications.
The primary risk is selecting a part with incorrect impedance, which will alter the circuit's noise filtering characteristics.
