Megastar
Matches key specs like 2.54mm pitch and straight mounting, with a higher current rating. Mechanical fit must be verified.
Finding a replacement for the WF-1A254A2P-R 2-pin header involves matching its 2.54mm pitch, straight through-hole mounting, and electrical ratings. Several alternatives exist but require careful mechanical verification.
Pitch and orientation may match, but housing dimensions and pin lengths require verification.
Candidates have equal or better voltage/current ratings.
No confirmed direct drop-in replacement is available. Candidates like Megastar's ZX-HA2.54-2PZZ-R match key parameters but require mechanical verification.
Functional alternatives from Megastar like the ZX-HA2.54 series match key specs but require datasheet review for mechanical fit.
The primary risk is mechanical incompatibility, specifically minor differences in housing dimensions or pin length, even with matching pitch.
