Is there a pin-compatible replacement for UK-2.54-2AWT?

No, a direct pin-compatible SMT replacement for UK-2.54-2AWT was not found in the provided candidates. All reviewed parts have a different mounting style (Through-Hole) that requires a different PCB footprint.

What risks should I check before replacing UK-2.54-2AWT?

The main risk is the package mismatch. The target is a Surface Mount (SMT) part, while alternatives are Through-Hole (TH). This requires a complete PCB layout change and a different soldering process, which has significant design and manufacturing implications.

AI replacement insight

Package riskhigh

Requires changing PCB layout and assembly process from SMT to Through-Hole.

Electrical risklow

Key electrical ratings like voltage and current match on functional alternatives.

Can it be replaced directly?

No, there are no direct SMT replacements for UK-2.54-2AWT in this list. All candidates are through-hole and require board redesign.

Best replacement path

Consider through-hole alternatives like ZX-XH2.54-2PWZ-R if a PCB layout change from SMT to through-hole is feasible.

Main risk

The primary risk is the mechanical incompatibility; the target is Surface Mount (SMT) while all viable alternatives are Through-Hole (TH).

Recommended alternatives

Functionally similar with same pitch and ratings, but requires a board change from SMT to Through-Hole.
