mouser lists the bf245a as obsolete and only has an SMD replacement.

are there any replacements that have the same form factor (and ideally the same pin out)

Thanks

Did a quick google and it seems that a J201 or 2N5457 might work, but mind the reversed pin outs! Check the data sheets to be sure. This: http://alltransistors.com/mosfet/transistor.php?transistor=1229 gives you the chance to look for a closer match if your circuit is really built around that specific transistor. To be safe, socket the thing!
