Same-size TDK ACT1210 option with different impedance and lower current.
ACT1210-510-2P-TL00 is an automotive 3225 common-mode choke. Reviewed alternatives need FAE checks before use.
Impedance, inductance, current, or DCR differ.
ACT45B uses 4532, not 3225.
Passive part; no firmware impact expected.
Some lifecycle fields are dash values.
Direct replacement for ACT1210-510-2P-TL00 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Start with TDK ACT1210-101 or ACT1210-110 only if the EMI and current margins are acceptable.
Common-mode impedance curve and pinout are not fully verified.
