Hmmm. The first two links go to 404 (not found) errors, and then browsing the Arrow site gave access denied permissions problems - the combination of their site and my browser don't seem to get on, shame as Arrow looked interesting enough to browse. Thanks for the post, will try again another day.

--- Quote from: Whales on January 30, 2020, 07:02:23 am ---As a sidenote: for some very basic parts greymarket can be acceptable, but only if you know what to expect.  I would consider all of eBay to be greymarket, it's really hard to find "legit" suppliers without trial and error (and even then they may be clueless -- could have just obtained a good lot of stock by chance). 

If you order 100pcs 2N2222 from eBay then you will get ~100pcs of some form of TO-92 NPN transistor.   I use them as my first line of experimental fodder and only move to better parts where necessary.

Similar for "IRF540" N-FETs (some form of TO-220 N-fet silicon).

Don't buy opamps other than LM328s :P

Sometimes the footprints are mirrored -- a $20 transistor tested is a worthwhile investment in the world of greymarket.

Anyway, buy from whoever you are comfortable with.  First party suppliers are often screwy over shipping, don't expect the world from them.  Regardless of what you do: try to enjoy your orders.

The comment about all eBay being regarded as grey market or caveat emptor is a good one, as I've already found, fortunately nothing too bad but disappointting nevertheless.

I have taken on board your comments and those in previous posts, and plan to buy from more trustworthy sources at least for now.

@MosherIV & @bd139

Well several have made much the same recommendation:

Since op is UK based, you can also try

bitsbox.co.uk

Small company supplying hobby market. Good quality parts. Fixed price postage, so worth building up parts list to large order.
I have personally used them and can vouch for them, even recommend them.

--- Quote from: bd139 on January 30, 2020, 10:06:28 am ---bitsbox has gone down the shitter this year. They started stocking hair legged crap resistors. I had some turn up with corrosion! The capacitors have gone to poo as well.

--- End quote ---
A little too late for my first order!

Having seen the positive comments about bitsbox.co.uk and needing some bits for a project, I decided to place my first (fairly modest) order -and have been pleased (as far as a visual inspection can tell) with the quality and the delivivery speed was pretty darn fast, so for now they seem OK here, fingers crossed.

The capacitors have gone to poo as well. Also lets not mention CPC - I have a whole thread on how crap they are :D

Tayda Electronics ( https://www.taydaelectronics.com/ ) is a good source. All semis seem good. You don't need a lot of parts. I have built a lot of things from parts from there and never found an issue with anything out of spec. Also if you pick their snail mail option you NEVER get done for import duty. I've ordered $100 of stuff from them and not been charged.

Good jelly bean semiconductor kit from Tayda:

50x 2n3904
30x 2n3906
10x 2n4401 (good enough switching replacement for 2n2222 etc)
50x 1n4148
20x 1n4007
5x MJE3055

Total $5.94 inc delivery from Thailand. Takes 1-2 weeks to turn up. Is tracked and reliable. That doesn't even touch their minimum order. Also as it's outside EU then import situation will not change over next few months.

also

1. dont bother with bc547/559 - sub for 3904/3906
2. dont bother with 2n3055 - obsolete. Use MJE3055 instead. To220 - easier to mount. OR something larger if you need it. All ebay 2n3055's unless vintage in lots are probably fake. Proper ones cost £5 a go and are after market. They are dead and gone. I have a large box of old ones (1970s date codes) floating around.

If you want jellybean discrete parts, they sell them as well. If you buy resistors from them, get the Royal Ohm 1% 0.25W ones. They are excellent. I mean really good. I stock up in 50/100 quantities of each value as it runs out every 3 months or so as I get through loads of them:



The "multicomp" 0.25W 1% resistors that CPC sell are also the same resistors if you have to use them but a crap load more expensive.

Best bet is buy your "jelly bean parts" in bulk from Tayda and keep stock and then top up with extras as you need them from RS (free delivery). RS are pretty good on some part pricing. For example: 10x PN2222A  = £0.30 including next day parcel force delivery  :-DD

Nice! Tayda Electronics do look good - but can you share a link to the "Good jelly bean semiconductor kit" please?
 I've browsed pretty much every section - and can't seem to find any such bumdle on offer - what did I mess?


Also, the "don't bother with xxx" comments are well made and appreciated, thank you!
As my education, training, and initial professional electronics took place 30-40 years ago, have recently returned I'm still updating the normal components to use, such as MJE3055 instead instead of the ancient 2N3055 - I was actually very pleasantly surprised to recognise so many of the items in use (7400 series, 4000 series, 2N2222 and so on) from my day, so a few chnages are easy enough to accomodate.

Do please feel free to suggest any other such chnages as you think of them, I'll be very grateful for such ideas.

Especially if you can show me the Good jelly bean semiconductor kit URL I missed, I do indeed intend to place a jellybeans items order soon-ish with Tayda - and will indeed keep RS, Farnell et. al in reserve for fill-in orders too, thanks for the advice.

Ah, will pop over and read up that thread, thank you for sharing it.
 (This site is so big and busy it's a tad off-putting for a newcomer - and easy to miss the obvious - or is that just me?)


@fourfathom

--- Quote from: fourfathom on January 30, 2020, 04:18:54 pm ---Tayda - yes! I've bought a lot of stuff from them and it's all been good.

I'm in the USA and I usually buy from Digi-key or Mouser since they have a great inventory and reasonable prices. Yes, you can find cheaper jellybean parts elsewhere but you know what you're getting.

--- End quote ---
Good to know you like Tayda, and have noted a number of US folk also like Digi-key and Mouser - will see how they look from a "post to UK" perspective. The comment " but you know what you're getting " is well made in light of my previous eBay orders, so agree with you (now) wholeheartedly!
