Is there a pin-compatible replacement for NCE6005AR?

Diodes Inc. DMN6068SE uses the same SOT-223 package and has a compatible pinout (G-D-S). However, it is not a direct drop-in due to different electrical characteristics.

What risks should I check before replacing NCE6005AR?

When replacing NCE6005AR, check the Vds (must be ≥60V) and Id (must be ≥5A). Also, verify the Rds(on), as a higher value will increase heat and lower efficiency.

Finding a replacement for the NCE6005AR 60V N-Channel MOSFET requires matching its SOT-223 package and key electrical ratings like Vds, Id, and Rds(on).

AI replacement insight

Electrical riskmedium

Higher Rds(on) increases power loss and heat, impacting efficiency and thermal stability.

Package risklow

The SOT-223 package is standard and the pinout is compatible.

Can it be replaced directly?

No direct, drop-in replacement with identical or better performance was found. DMN6068SE is a functional alternative with caveats.

Best replacement path

The best path is to find a MOSFET in a SOT-223 package with Vds ≥ 60V, Id ≥ 5A, and Rds(on) ≤ 35mΩ. DMN6068SE is a functional downgrade to consider if a better match is unavailable.

Main risk

The primary risk is thermal performance due to candidates having higher on-resistance (Rds(on)).

Recommended alternatives

A functional alternative in a compatible SOT-223 package, but with significantly higher on-resistance.
