    \$\begingroup\$ If dimensions match, perhaps Toshiba PNP transistor RN2131F? datasheet Can you show some more of the board and the surrounding parts, that really helps give context \$\endgroup\$

    \$\begingroup\$ Most definitely a wider angle picture is needed - this part can literally be anything, but with some context it should be possible to narrow down the possibilities. \$\endgroup\$
