Is there a pin-compatible replacement for DB301V-5.0-3P-BU-S?

Several terminal blocks share the same 3-pin, 5.0mm pitch footprint, making them mechanically compatible. However, no direct pin-to-pin replacement with identical electrical ratings has been identified; all candidates require review.

What risks should I check before replacing DB301V-5.0-3P-BU-S?

The main risk is electrical stress. Verify the candidate's current rating (Amps) is sufficient for your design, as many similar parts have a lower rating. Also confirm mechanical dimensions and wire entry orientation.

Finding a substitute for the DORABO DB301V-5.0-3P-BU-S terminal block involves matching its 3-position, 5.0mm pitch, and electrical ratings. Several alternatives exist, but require careful review of current ratings.

AI replacement insight

Electrical riskmedium

Most candidates have a slightly lower current rating (15A vs 16A), requiring application review.

Package risklow

The 5.0mm pitch, 3-pin vertical package is a common standard with many mechanical matches.

Can it be replaced directly?

No direct, drop-in replacement with identical ratings was found. The closest options have a slightly lower current rating.

Best replacement path

Review DB126V-5.0-3P-GN from the same manufacturer, accepting a minor current downgrade from 16A to 15A.

Main risk

Current rating mismatch. Most alternatives are rated for 15A, while the target is 16A.

Recommended alternatives

A form-fit match from the same manufacturer, but with a slightly lower current rating (15A vs 16A).
