AI replacement insight

Package riskmedium

Footprint and body dimensions must be verified from datasheets.

Electrical risklow

Several parts match voltage, but some have lower current ratings.

Can it be replaced directly?

No confirmed direct drop-in replacement exists without engineering review. WJ128V-5.0-02P-14-00A is the closest functional match and requires datasheet comparison for pinout dimensions.

Best replacement path

WJ128V-5.0-02P-14-00A from the same manufacturer offers identical voltage and current ratings, but requires verification of wire gauge compatibility and mechanical dimensions.

Main risk

The primary risk is mechanical incompatibility. While several parts match pitch and position, their body dimensions and pin footprints may differ.

Recommended alternatives

A strong alternative from the same manufacturer with matching electrical ratings; check wire gauge and footprint.
