AI replacement insight

Package risklow

Form, fit, and pitch are standard and alternatives are available.

Electrical riskmedium

Downgrades in contact plating (Gold to Tin) and temperature range require application-specific review.

Can it be replaced directly?

No direct drop-in replacement with identical specifications was found. All viable alternatives have downgrades in contact plating or temperature range that must be reviewed.

Best replacement path

TE Connectivity 640456-4 offers the best form-fit match but requires accepting tin plating instead of gold.

Main risk

Contact plating downgrade from Gold to Tin, impacting long-term reliability and contact resistance.

Recommended alternatives

A form-fit compatible header from TE Connectivity, but with Tin-plated contacts instead of Gold.
