Is there a pin-compatible replacement for NCEP0178AK?

While several parts like NCE0130KA share the TO-252 package and are likely pin-compatible, none match the critical electrical ratings of NCEP0178AK. They represent a significant electrical downgrade.

What risks should I check before replacing NCEP0178AK?

The primary risks are overheating and failure due to higher on-resistance (RDS(on)) and lower continuous current rating (ID). Always verify the thermal performance and ensure the substitute can handle your application's load.

NCEP0178AK is a 100V, 78A N-Channel MOSFET in a TO-252 package, notable for its very low 7.2mΩ on-resistance. Finding a suitable replacement requires matching these high-performance electrical characteristics to avoid circuit failure.

AI replacement insight

Electrical riskhigh

Substitutes have much higher RDS(on) and lower ID, leading to high power loss and potential failure.

Package risklow

The TO-252 package is standard, but pinout must always be verified via datasheet.

Can it be replaced directly?

No direct 1:1 replacement was identified. All reviewed options present a significant downgrade in current handling and on-resistance.

Best replacement path

Seek a modern trench MOSFET with VDS ≥ 100V, ID ≥ 78A, and RDS(on) ≤ 7.2mΩ in a TO-252 package.

Main risk

Thermal overload and circuit failure due to the much higher on-resistance and lower current rating of any potential alternative.

Recommended alternatives

A lower-spec alternative with matching package and voltage, but much lower current and higher resistance.
