A 4-pin, 2.5mm pitch, right-angle SMT header with matching electrical ratings but different contact material.
Reviewing alternatives for the SHOU HAN 2.54-4PWTDK, a 4-pin 2.5mm pitch right-angle SMT header. Key considerations for substitutes are matching the SMT footprint, right-angle orientation, and ensuring material compatibility.
SMT footprint must be verified via datasheet to ensure it matches the PCB layout.
Key voltage and current ratings are matched by several candidates.
Multiple alternatives exist, but require careful vetting before procurement.
No verified direct replacement is available. Candidates like BOOMELE XH-4AWD and FG XH-4AWT are promising but require engineering review of their datasheets for footprint and material compatibility.
