| Any MOSFET similar of ULN2003? |

Only 100mA? Why not just any small cheap FET, eg. 2N7002? If you need a flyback diode, add one externally. Or you could choose jellybean BJTs if you don't like FETs. |

It's easier though to manually pick and place a single component. |

Something like a dual N-channel MOSFET in SOT26? Two pieces of this ought to work: http://docs-europe.electrocomponents.com/webdocs/104e/0900766b8104e4cc.pdf |

http://www.utsource.net/ic-datasheet/TPIC2701N-786242.html I've ordered from UTSource several times and have always been happy. Generally takes 10-12 days from ordering to delivery in my mailbox in Texas. |
