WAFER-PH200Z-3A
HANBO
Needs validationmedium risk
A functional alternative with a lower current rating (2A vs 3A); verify application requirements before use.
Best Alternatives to B03B-PASK(LF)(SN)
The JST B03B-PASK(LF)(SN) is a 3-position, 2.0mm pitch straight header from the PA series, rated for 3A and 250V. Finding a direct replacement requires matching the specific shrouded dimensions and higher current rating.
AI replacement insight
Electrical riskhigh
Most alternatives have a lower current rating (2A vs 3A).
Package riskmedium
Shroud dimensions and PCB footprint must be verified from datasheets to ensure mechanical and mating compatibility.
Sourcing risklow
2.0mm pitch headers are common, but finding a 3A rated version is more difficult.
Can it be replaced directly?
No direct drop-in replacement has been confirmed. Most similar parts have a lower current rating of 2A compared to the target's 3A, posing an electrical risk.
Best replacement path
The safest path is another JST PA series straight header or a certified cross-reference. If unavailable, a form-fit part like PH-3P立贴 should be evaluated by checking its datasheet for 3A/250V capability.
Main risk
The primary risk is electrical downgrade; most available 2.0mm 3-pin headers are rated for 2A, not the 3A of the JST PA series target.

Questions & answers
The best alternatives are other 2.0mm pitch headers, but most are rated for 2A, which is a downgrade from the 3A target. A part like BOOMELE's PH-3P立贴 is a potential form-fit match, but you must verify its electrical ratings from the datasheet.
