I found several possible matches. Perhaps if you draw the symbol and
attach the image to the thread, we can see what it is. Anyway, here is
what I found (MOSFETs):
Calogic - BSS138
Fairchild Semi - BSS138
Infineon - BSS138
Infineon - BSS138E6327
Infineon - BSS138E6433
Motorola - BSS138LT1
Motorola - MRF138
ON Semiconductor - BSS138LT1
ON Semiconductor - MRF138
Philips Semi - BSS138
Sanyo - FSS138
Sanyo - FW138
Zetex - BSS138
I checked a couple, and they where N-channel. The specs vary widely.
Based on the circuit, you should be able to find some suitable replacement.
