Needs validationlow risk
A strong functional alternative from the JST VH series with matching pitch, pin count, and mounting style.
Best Alternatives to 640445-2
The TE Connectivity 640445-2 is a 2-position, 3.96mm pitch through-hole header. When seeking alternatives, focus on cross-vendor VH-series compatible connectors with matching mechanical dimensions and current ratings.
AI replacement insight
Package riskmedium
Footprint is standard, but shroud dimensions and pin length can vary.
Electrical risklow
Most alternatives have similar or better voltage/current ratings, but some may be lower.
Sourcing risklow
This is a common connector style with many suppliers.
Can it be replaced directly?
No confirmed direct drop-in replacement is available without manual datasheet review. Several form-fit-function alternatives exist but require engineering verification.
Best replacement path
Cross-vendor VH-series compatible headers.
Main risk
Mechanical incompatibility (footprint, height, pin length) and potential differences in current rating.
