Is there a pin-compatible replacement for KF128-5.0-2P?

No, a direct pin-compatible replacement has not been confirmed. The most similar parts found have a 5.08mm pitch, while the original has a 5.0mm pitch. This small difference prevents it from being a guaranteed drop-in fit.

What risks should I check before replacing KF128-5.0-2P?

The main risk is the mechanical fit due to the pitch difference (5.0mm vs 5.08mm). Always verify your PCB footprint. For other candidates, check for lower current ratings or smaller supported wire gauges, which could pose electrical or safety risks.

KF128-5.0-2P Alternatives, Datasheet & Cross Reference | CIXI KEFA ELECTRONICS CO., LTD.

Finding a substitute for the KEFA KF128-5.0-2P screw terminal involves checking physical and electrical parameters. While functional matches exist, the key challenge is the 5.0mm pitch, as many alternatives use a 5.08mm pitch.

AI replacement insight

Package riskhigh

Pitch mismatch (5.0mm vs 5.08mm) may prevent assembly without PCB modification.

Electrical risklow

The top candidate matches all key electrical ratings, but others are downgrades.

Can it be replaced directly?

No direct, drop-in replacement with a matching 5.0mm pitch and identical ratings has been identified. All close candidates have a 5.08mm pitch.

Best replacement path

The closest option is KF128-5.08-2P-AA, which is electrically identical but has a 5.08mm pitch. This requires verifying if the PCB footprint can accommodate the 0.08mm difference.

Main risk

The primary risk is physical incompatibility due to the pitch mismatch between the target's 5.0mm and candidates' 5.08mm spacing.

Recommended alternatives

Functionally identical but has a 5.08mm pitch; requires PCB layout verification.
