Is there a pin-compatible replacement for DB128V-5.08-3P-GN-S?

Several parts like XY2500V-D-5.08-3P share the same 5.08mm pitch and 3-pin vertical layout, making them likely footprint-compatible. However, electrical differences require engineering review before substitution.

What risks should I check before replacing DB128V-5.08-3P-GN-S?

Check the current rating (many alternatives are lower than 16A), the accepted wire gauge range (some accept smaller wires), and confirm the physical footprint and wire entry orientation from the datasheet.

AI replacement insight

Package risklow

Several candidates share the 5.08mm pitch and vertical orientation.

Electrical riskmedium

Most alternatives have lower current ratings or support smaller wire gauges.

Sourcing risklow

Multiple cross-vendor options are available.

Can it be replaced directly?

No exact drop-in replacement was found. XY2500V-D-5.08-3P is the closest functional match but has a slightly lower current rating (15A vs 16A).

Best replacement path

XY2500V-D-5.08-3P is a strong candidate, matching form and voltage, with only a minor 1A current reduction. Verify footprint and current needs.

Main risk

The primary risk is electrical mismatch, specifically lower current ratings or smaller supported wire gauges in most alternatives.

Recommended alternatives

A form-fit-function alternative with the same pitch and voltage, but a slightly lower current rating.
