Procurement Notes

Verify that the specific part number matches the required contact count and orientation. Confirm that the through-hole mounting style aligns with the target PCB design. Ensure compatibility with mating sockets regarding pitch and height specifications. Check for any specific handling requirements during assembly processes.

Selection Notes

Select this component when a single-row, right-angle male header is required for board-to-board applications. Consider the 2.54 mm pitch as the standard spacing requirement. Evaluate the 3 A current rating against the circuit's power needs. Ensure the operating temperature range meets the environmental conditions of the final product.

Part Context

This component belongs to the AW140 series, which offers various configurations including different pin counts and orientations. The series is designed for general-purpose electronic applications requiring robust connectivity. Similar parts in the series may differ in contact quantity or angle, but share common electrical ratings and material properties.

Replacement Considerations

Compatible substitutes include other 21-pin, 2.54 mm pitch, right-angle male headers from Assmann WSW or other manufacturers. Verify that replacement parts match the current rating, voltage rating, and terminal type. Ensure the housing material and plating specifications are equivalent to maintain performance standards.
