Is there a pin-compatible replacement for JK60-050?

Yes, parts like JK60-075 and JK130-025 share the same radial package with 5.1mm lead spacing, making them physically compatible. However, their electrical characteristics, especially hold current, differ and must be reviewed.

What risks should I check before replacing JK60-050?

The primary risk is mismatched hold current. A higher hold current (e.g., JK60-075) reduces protection, while a lower one (e.g., JK130-025) may cause nuisance tripping. Always verify the candidate's voltage rating is at least 60V.

AI replacement insight

Electrical riskmedium

Hold current differences require engineering validation.

Package risklow

Candidates with matching radial packages are available.

Can it be replaced directly?

No direct 1-to-1 replacement is identified. All close alternatives require reviewing the change in hold current, which affects circuit protection.

Best replacement path

JK60-075 is the closest option within the same product family, but requires accepting a higher hold current.

Main risk

Mismatched hold current, which can either reduce circuit protection (if higher) or cause nuisance tripping (if lower).

Recommended alternatives

A form-fit alternative from the same series with identical voltage but a higher hold current of 0.75A.
