I hope I haven't made a mistake here. Rather than
go to Farnell where I need
a minimum order amount, I looked on Ebay and found someone with some TIP125s
there.
I had assumed they were all the same and just chose this one:
http://www.ebay.co.uk/itm/TIP125-Transistor-/290672643190?pt=LH_DefaultDomai
n_3&hash=item43ad708c76.
I haven't spent a lot, so if I have bought the wrong thing it is no big deal
to go and find the right ones instead. On the original the only other
marking (apart from a TI logo) is "8702", but my web searches don't seem
to
indicate that this means anything. The Ebay one has no other markings to
help me distinguish anything either. So, I don't know if I have bought the
wrong thing or not.
Are they all likely to be similar enough not to matter? Or should I be
looking for a closer match? Not that I know what a closer match would be.
No, a TIP125 is a TIP125. Any manufacturer's version will meet the same
minimum specs, or else they'd call it something else. I'd guess the
8702 on the Texas ones is a date code (week 2 1987).
