KEFA
Needs validationhigh risk
Functionally equivalent with identical electrical ratings, but has a different 5.08mm pitch.
Best Alternatives to KF103-5.0-2P
KEFA KF103-5.0-2P is a 2-position, 5.0mm pitch screw terminal block rated for 250V/24A. While no direct drop-in replacements have been identified, several functional alternatives with similar electrical ratings or form factors are available for consideration.
AI replacement insight
Package riskhigh
Many candidates have a 5.08mm pitch, which is incompatible with the target's 5.0mm PCB layout.
Electrical riskhigh
Candidates with the correct pitch have a significantly lower current rating (15A vs 24A).
Sourcing risklow
All candidates are from the same manufacturer, KEFA, and are listed as Active.
Can it be replaced directly?
No direct drop-in replacement has been identified. All candidates have critical differences in mechanical pitch or electrical current rating.
Best replacement path
For a board revision, use KF128L-5.08-2P for identical electricals. For existing boards, consider KF127-5.0-2P but verify the lower 15A current rating.
Main risk
Mechanical incompatibility due to pitch mismatch or electrical failure due to current rating downgrade.
