TE Connectivity
Needs validationmedium risk
A very strong alternative from the same TE Connectivity MTA-100 series; likely differs only in a minor detail like pin length.
Best Alternatives to 640454-2
The TE Connectivity 640454-2 is a standard 2-position, 2.54mm pitch male header. Several form, fit, and functional alternatives are available from TE and other manufacturers, offering flexibility in sourcing.
AI replacement insight
Package riskmedium
While pitch and mounting type match, pin length and housing dimensions must be verified from datasheets to ensure proper fit.
Electrical risklow
Most alternatives have similar or better voltage/current ratings, but these should be confirmed for the specific application.
Sourcing risklow
This is a common connector type with multiple vendors, suggesting good sourcing availability.
Can it be replaced directly?
Direct replacement for 640454-2 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
The TE Connectivity part 3-644456-2 is the most promising alternative as it belongs to the same MTA-100 product series. Other strong options include WF-1A254A2P from BXCONN and RE-H022TD-1190(LF)(SN) from JST.
Main risk
The primary risk is a mismatch in mechanical dimensions, specifically pin length and housing height, which could affect PCB assembly and mating with the corresponding female connector.
