AI replacement insight
Package riskhigh
Mechanical drawings for shroud dimensions, pin length, and mounting features must be verified.
Electrical riskmedium
Some alternatives have lower voltage or current ratings, which must be checked against application requirements.
Sourcing risklow
This is a common connector type with many cross-vendor options available.
Can it be replaced directly?
Several candidates match the key electrical and physical parameters, but none can be confirmed as a direct, drop-in replacement without verifying mechanical drawings for footprint and shroud compatibility.
Best replacement path
Verify mechanical drawings for B05B-PASK-1(LF)(SN) or ZX-HY2.0-5PLT. B05B-PASK-1(LF)(SN) offers a higher current rating but may have a mounting boss.
Main risk
The primary risk is mechanical incompatibility. Several candidates have different shroud dimensions, or features like mounting bosses, that could prevent a proper fit on the PCB.
