AI replacement insight

Package riskmedium

Cross-vendor parts require datasheet verification of footprint and height.

Electrical risklow

Most candidates match or exceed voltage/current ratings.

Can it be replaced directly?

Yes, several direct replacements exist. The strongest are upgraded versions from the same manufacturer, XUNPU, such as WAFER-XH2.54-4PLB.

Best replacement path

Use same-manufacturer upgrades like WAFER-XH2.54-4PLB or WAFER-XH2.54-4PJK for a higher 3A current rating with minimal qualification risk.

Main risk

The primary risk when substituting connectors is mechanical incompatibility. Even with matching pitch and pin count, housing dimensions or keying can differ.

Recommended alternatives

Cross-vendor upgrade with a higher 3A current rating and matching form-factor.
