Is there a pin-compatible replacement for FNR6028S100MT?

Yes, other inductors in the cjiang FNR6028S series, such as FNR6028S180MT and FNR6028S220MT, share the same 6028 package and are pin-compatible. However, their electrical characteristics are not identical.

What risks should I check before replacing FNR6028S100MT?

Before replacing, check three key risks: 1) Lower Current Rating (Irms/Isat) may cause overheating or saturation. 2) Inductance Mismatch can alter the circuit's frequency response or stability. 3) Higher DC Resistance (DCR) will increase power loss and heat.

FNR6028S100MT is a 10µH, 2.4A shielded power inductor in a 6x6mm SMD package. While no direct drop-in replacements are available, alternatives within the same FNR6028S family exist but require careful review of their different electrical parameters.

AI replacement insight

Package risklow

Alternatives from the same series share the 6028 package, ensuring form and fit.

Electrical riskmedium

Candidates have lower current ratings, higher DCR, and different inductance. Circuit validation is mandatory.

Can it be replaced directly?

No direct, drop-in replacement was identified. All potential alternatives have different inductance values and lower current ratings, requiring engineering review.

Best replacement path

The best path is to select another part from the cjiang FNR6028S series, which shares the same package. However, all options require careful validation of electrical parameters.

Main risk

The primary risk is the lower current handling capability and different inductance values of available alternatives, which can impact circuit performance and reliability.

Recommended alternatives

Same package and family, but has higher inductance (18µH) and lower current rating (1.6A).
