Many styles are available. If board space is a concern, 533202B02551G  meets the requirements. According to the graph shown on this slide, an airflow of 400’/min results in a thermal resistance of 3°C/W, which is less than the required thermal resistance of 5°C/W. In this situation, it should be acceptable. If height is a concern another option would be 533702B02552G, which is only 1.0” tall.
