Needs validationhigh risk
Functionally similar with same electrical ratings, but is a straight header, not right-angle.
Best Alternatives to ZX-5557-4.2-2-2PWZ
Finding a substitute for the ZX-5557-4.2-2-2PWZ, a 4-pin right-angle header, requires careful attention to mechanical details. While several parts are electrically similar, matching the right-angle form factor is key for a successful replacement.
AI replacement insight
Package riskhigh
Most alternatives have a straight orientation instead of right-angle, requiring a board redesign.
Electrical risklow
Several candidates meet or exceed the target's voltage and current ratings.
Can it be replaced directly?
Direct replacement for ZX-5557-4.2-2-2PWZ should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.
Best replacement path
HC-5557-4.2-2x2AW is the most promising alternative as it matches the critical right-angle form factor and has superior electrical ratings. However, its footprint must be verified from the datasheet.
Main risk
The primary risk is mechanical incompatibility. Most alternatives are straight/vertical headers, which will not fit a PCB designed for the right-angle target part.
