AI replacement insight
Package risklow
Multiple candidates have the same straight through-hole form factor, but dimensions must be verified.
Electrical riskmedium
Several alternatives have a lower current rating (2A vs 3A), which is a critical downgrade.
Can it be replaced directly?
No verified direct drop-in replacement has been identified. WAFER-HA254Z-4A is a strong functional match requiring mechanical verification. Other options have a lower current rating.
Best replacement path
The strongest alternative is WAFER-HA254Z-4A from HANBO, which matches key electrical and mechanical specs, but requires dimensional verification. For lower power needs, BXCONN's WF-1A254A4P series is an option, but has a lower 2A current rating.
Main risk
The main risks are mechanical incompatibility (pin length, housing dimensions) and electrical downgrade (lower current rating in some alternatives).
