JST Sales America Inc.
Needs validationmedium risk
Matches form factor but has a lower voltage rating. Requires engineering review.
Best Alternatives to WAFER-PH2.0-2PWZ
WAFER-PH2.0-2PWZ is a 2-pin, 2.0mm pitch right-angle header. Alternatives exist but require careful review of mounting orientation and electrical ratings.
AI replacement insight
Package riskhigh
Most alternatives have a different (straight) mounting orientation.
Electrical riskmedium
Several candidates have lower voltage or current ratings.
Can it be replaced directly?
No direct, drop-in replacement is available. The closest candidate, S2B-PH-K-S(LF)(SN), has a lower voltage rating.
Best replacement path
Evaluate S2B-PH-K-S(LF)(SN) for its form-factor match, but only if the application's voltage is safely below 100V. Otherwise, a straight-mount connector must be considered.
Main risk
The primary risk is mechanical mismatch due to mounting orientation (straight vs. right-angle). The second major risk is electrical downgrade in voltage or current ratings.
