Is there a pin-compatible replacement for MLG1005S2N0BTD25?

Yes, several 0402 inductors are pin-compatible, such as Murata's LQG15HS series. However, none of the identified candidates match the target's AEC-Q200 automotive rating, so they are not drop-in replacements for automotive applications.

What risks should I check before replacing MLG1005S2N0BTD25?

First, verify if your application requires an AEC-Q200 qualified component. Also check for differences in Self-Resonant Frequency (SRF), inductance tolerance, and DC Resistance (DCR) to ensure circuit performance is not compromised.

TDK's MLG1005S2N0BTD25 is a 2nH, 900mA automotive-grade (AEC-Q200) inductor in an 0402 package for high-frequency circuits. Finding a replacement requires matching its RF performance and automotive rating.

AI replacement insight

Sourcing riskhigh

Finding a replacement with an AEC-Q200 rating is the main challenge.

Electrical riskmedium

SRF, tolerance, and DCR may differ, requiring circuit validation.

Package risklow

The 0402 package is a standard, ensuring physical compatibility.

Can it be replaced directly?

No direct, drop-in replacement has been verified. The closest candidates lack the target's AEC-Q200 automotive qualification, a critical feature for reliability in automotive systems.

Best replacement path

Find an AEC-Q200 rated, 2nH, 900mA inductor in an 0402 package. Murata's LQG15HS2N0B02D is a strong parametric match but requires validation as it lacks the automotive rating.

Main risk

The primary risk is substituting a non-automotive grade component into a system requiring AEC-Q200 compliance, potentially affecting long-term reliability.

Recommended alternatives

Strong parametric match for non-automotive use; inductance and current match, but lacks AEC-Q200 rating.
