YLM2012-900T is a 90Ω, 400mA, 2-line 2012 common mode choke. Listed alternatives need electrical and pinout review.

AI replacement insight

Electrical riskhigh

All kept parts are 300mA, not 400mA.

Package riskmedium

2012 package matches, pinout is not verified.

Firmware risklow

Passive EMI part; no firmware impact shown.

Sourcing riskmedium

Lifecycle fields are limited.

Can it be replaced directly?

Direct replacement for YLM2012-900T should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

Check YLM2012-261T first only if 300mA and 260Ω are acceptable.

Main risk

Lower current rating and higher impedance may affect margin and signal integrity.
