Headers, Male Pins Procurement Notes

Verify the specific suffix 'MR1' against the manufacturer's latest datasheet to confirm exact plating thickness and mating partner compatibility. Ensure the right-angle configuration matches the mechanical constraints of the target PCB layout. Cross-reference the 42-position count with the required circuit density to prevent mismatched orders.

Headers, Male Pins Selection Notes

Select this part when a right-angle surface mount header is required for high-density applications. The 2.54 mm pitch ensures compatibility with standard through-hole components. Verify that the PCB design accommodates the right-angle profile height. Confirm that the 3A current rating meets the thermal requirements of the specific application environment.

Headers, Male Pins Part Context

This component belongs to the ASSMANN WSW SL254 series, which specializes in standard pitch connectors. The series offers various configurations including straight and right-angle options in both through-hole and surface mount formats. The SL254 line is widely used in general-purpose electronics for its reliability and standardized dimensions.

Headers, Male Pins Replacement Considerations

Compatible substitutes include other 42-position, 2.54mm pitch, right-angle surface mount headers from manufacturers such as Molex or Samtec. Ensure the replacement maintains the same contact plating and insulator flammability rating. Verify mechanical footprint compatibility before substitution.
