WF-1B254A4P
BXCONN
Needs validationhigh risk
Functionally similar with matching orientation, but requires PCB redesign due to different mounting (Through-Hole vs SMT).
Best Alternatives to UK-2.54-4AWT
UK-2.54-4AWT is a 4-pin, 2.54mm pitch, right-angle male header designed for Surface Mount (SMT) applications. Finding a replacement requires matching the SMT footprint, orientation, and key electrical ratings.
AI replacement insight
Package riskhigh
All candidates require a different PCB footprint (Through-Hole vs. SMT), necessitating a board redesign.
Electrical risklow
Key electrical parameters like voltage, current, and pitch are well-matched across candidates.
Sourcing risklow
Multiple manufacturers produce functionally similar through-hole headers, but SMT versions must be sourced separately.
Can it be replaced directly?
No, a direct SMT replacement for UK-2.54-4AWT was not found in this review. All candidates are through-hole and mechanically incompatible.
Best replacement path
Search for alternative 4-pin, 2.54mm pitch, Surface Mount (SMT), right-angle headers. The candidates reviewed here are only functional matches and require board changes.
Main risk
The primary risk is the mechanical mismatch between the target's Surface Mount (SMT) package and the candidates' Through-Hole (TH) packages.
