The 7805 in one of my regulated supplies has failed. I was just going
to order one of the cheapest ones off of eBay. Most likely, this would

order a better brand and what are your suggestions? Thanks.

a) A princely $0.65 from Digi-Key.
b) Might this be a problem down the road? Three possible answers in the most likely-to-occur order:
- Yes, but not right away. So you will be making the same repair multiple times.
- Yes, but in such a way as to cause additional cascade failures - so you are putting the device at-risk.
- No.
In fewer words: Don't be stupid.

And, if you download the Digi-Key paper order form, fill it out by
hand, and mail it to Digi-Key with a check for the full cost of the component, they'll pay the shipping charge. Yes, they're still
offering this service (as of about three months ago) although they
don't go out of their way to publicize it.

Wow, I never knew this! Do I go ahead and pay shipping for which
they'll refund later, or just pay for the device?

Are there no electronic supply stores in your city/state? I'd try them
first. I do use DK and Mouser and Element 13 of course, but for single
and small orders I go to my local electronics supplier. In my case (Vancouver/Burnaby, BC, Canada) it is https://www.rpelectronics.com -
They have a showroom you can wander around in, perfect for hobbyists and hunting for something you can't recall the name of!

Just pay for the device, and include your local sales tax if any.
Don't pay for shipping.
To quote from their current Terms and Conditions document:
"6. Shipping Charges.
"Products Shipping from Digi-Key's Warehouse. Except as otherwise
provided on the Site, (1) shipping or freight charges and insurance
will be paid by the customer*, (2) all sales are made FOB Digi-Key's
warehouse in Thief River Falls, MN, USA, and (3) shipping or freight
charges from Digi-Key's warehouse in Thief River Falls, MN, USA are
prepaid and added to the invoice, billed collect or billed to a third
party.
"* When a check or money order accompanies your order, Digi-Key pays
all shipping and insurance (our choice for method of shipping) to all
addresses in the U.S. and Canada."
"Our choice of method for shipping" has always worked out to be the
same as their basic-price ground shipment, in my experience. The two
or three times I've used this method, I've not had a package delayed
unduely through having been sent on a slow horse via Mongolia, or
anything like that.
As far as I know there's no way to take advantage of this if you're
using their online ordering system, as you can't have a check or money
order "accompany your order". It might be possible to start the
process of order entry and then print out your "cart" and mail in the printout, but I'm not sure this would give them all of information
needed to process the order. I just download the PDF of their
paper order form, print it, fill it out by hand, and mail it with a
check. If I write my Digi-Key customer number in the right place,
I even get an email from them when they process the order.
This manual process is a nice thing if you want to order just one or
ten small items (where the parts cost is less than their normal
shipping charge) and you don't mind the order taking an extra week
or so.
You could dig out an old Digi-Key catalogue and use the order page from
that - I assume - to get your free shipping. Photocopies would probably
be fine.

RP Electronics? I wonder if they're the successor to the old
Rendell-Paret shop on 4th and Arbutus in Vancouver. That was a
real old-timey ham shop--stuff stacked to the rafters, and old
Hedley Rendell chain-smoking behind the counter.
I used to buy stuff there when I was a kid. Freaking ex-pen-sive
compared to now.
Cheers

I take it you grew up in Vancouver, BC.
I started out in Toronto. Great surplus stores in Toronto back in the
60s!
You knew Rendell Paret back in those days? I used to love hanging out
in that old shop too, along with the other electronics surplus store
(run by Peter - AIR) at Main and 17th or there about. Peter had very
nice monstrous TEK surplus oscilloscopes that I couldn't afford back
in the late 70s and early 80s...And of course Main Electronics around
Main and 29th - but they are all gone now.
RP sold out to Andrew back in the 90s I believe and he kept the name
ever since. No longer surplus, which is a shame, but that market
kinda dried up. And the High schools in Vancouver no longer have
electronics as a course - although they do have robotics and other
tech classes.

Sure. Or, web-search the phase "digi-key order form" and you'll quickly
find the PDF version.

I ordered from Digikey via the snail mail system to avoid shipping.
Ordered some other goodies too. Where I live, I think I'd be locked up
if I tried dumpster diving. They won't pull you over for driving like a jacka** through town, but if they see you taking stuff out of the
dumpster, look out!

That seems like bad business: processing a paper order is going to be
much more expensive than an automated online order. And it encourages itsy-bitsy orders which are certainly money losers. I suppose that it's basically a customer-relations thing & not for-profit.
I like DigiKey and try not to abuse their no-minimum with trivial
orders. And when I do, I'm happy to pay for shipping.
Please don't get me wrong - I have pulled many gems 'off the curb'... And I am not above salvaging parts, either. But I will not go diving for a random bit of electronics when I know that I will be able to find a genuine part at a small cost that isboth new and warranted.
