AI replacement insight

Electrical riskhigh

Most alternatives have significantly lower voltage and/or current ratings.

Package risklow

The 2.54mm 2x5 straight header is a very common form factor.

Can it be replaced directly?

No direct, fully-equivalent replacement has been verified. All candidates require engineering review due to differences in electrical ratings.

Best replacement path

Use a part with a matching footprint like A2541WV-2x5P, but only if the application can tolerate a lower voltage rating of 250V.

Main risk

The primary risk is using a substitute with a lower voltage or current rating, which could compromise circuit safety and reliability.

Recommended alternatives

Similar form factor and current rating, but a significantly lower voltage rating requires careful review.
