AI replacement insight
Electrical riskmedium
Several alternatives have a lower 2A current rating versus the target's 3A.
Package risklow
Most candidates share the standard 2.54mm pitch straight header form factor.
Sourcing risklow
Multiple manufacturers produce compatible XH-style connectors.
Can it be replaced directly?
No drop-in replacement is verified without datasheet comparison. WAFER-XH2.54-4PLB is the most promising candidate, but requires mechanical verification.
Best replacement path
Use WAFER-XH2.54-4PLB for a same-manufacturer option or WAFER-XH254Z-4A for a cross-vendor alternative, after verifying datasheet drawings.
Main risk
The main risk is selecting an alternative with a lower current rating (2A instead of 3A), which could cause overheating or failure.
