Is there a pin-compatible replacement for MLG1005S4N7CT000?

Yes, candidates like VHF100505HQ4N7ST and LQG15HS4N3B02D use the same 1005 (0402) package and pinout. However, as they are not from the same series, they are classified as functional alternates requiring electrical review.

What risks should I check before replacing MLG1005S4N7CT000?

Key risks include differences in inductance value, self-resonant frequency (SRF), and DC resistance (DCR). Always verify these parameters against your circuit's requirements, especially in tuned RF applications.

MLG1005S4N7CT000 Alternatives, Datasheet & Cross Reference | TDK Electronics AG
