AI replacement insight
Package riskmedium
Mechanical dimensions and footprint must be verified from datasheet.
Electrical riskmedium
Some alternatives have a lower current rating (2A vs 3A).
Can it be replaced directly?
No drop-in, datasheet-verified pin-to-pin replacement has been identified. However, parts like Megastar's ZX-HA2.54-2PZZ-Y are strong candidates that require engineering review of their datasheets for dimensional compatibility.
Best replacement path
Megastar's ZX-HA2.54-2PZZ series offers a strong functional match, requiring only dimensional verification. BXCONN parts are options if a lower 2A current rating is acceptable.
Main risk
The primary risk is ensuring the substitute's mechanical dimensions and footprint match the PCB layout. A secondary risk is accepting a lower current rating with some alternatives.
