I have an 18 year old Panasonic phone. still what to use, as it has 5 mailboxes plaus call forwarding when I receive messages...
The transistor to be replaced is a 2SD2137. It shows in cross-ref. as OEM only.
My real question is how can I find similar transistors to try out and substitute? I know it is chancy, however, i would like to try and save this thing.
I have the Data sheet
Is there a method of searching Cross Reference guides by the semiconductor specifications instead of by part number?
