Ok bascially I just want some standard single row female pin sockets and male pin headers!! Id like them 1x2 and 1x8. I also need some of the round kind of single row females machine pinned or whatever the ones you guys use for removable passives like xtals. Im just having the hardest time finding them idk if im just not looking in the correct places on digikey or what but1x8s are like 1.50, when you need 4 thats a bit ridiculous almost as much as an acual prop. Anyone got header advice?? I really need to make an order tonight I need caps!!

    Try Jameco. They usually have better pricing on that sort of thing than DigiKey or Mouser.

    Poke around this site.

    When you only need four then it seems rather costly in terms of time to go hunting around to get them cheap. I buy connectors from 4UCON but you have to buy in quantities of 1,000 etc. However 40 PIN 0.1" headers are only 9.2 cents each so if you were going to buy 100 elsewhere at $1 a piece then it makes more sense to buy the 1,000 for less (as long as you need more). Smaller quantities at cheap prices (but not that cheap) can be found on ebay.

    A word of advice, do not mount your crystals in machine pin sockets as this is problematic and although convenient would only be advised for prototypes where you are experimenting with different crystals.

    I agree with Peter. There's usually somebody selling those on eBay for cheap. Last fall I needed a few and bought 50 male and 25 female (all 40 pin, easy to trim down if you don't mind losing a pin in the process) for about $10 (shipping included). I resold what I didn't need for a profit. In the end I think I came out about $5 ahead, and I still have about half of the male headers.


    edit: Here are the ones I bought:

    I have a stock of headers that are 1x50 digikey PN SAM1035-50-ND and cut them apart to whatever length I need. I do the same thing with female headers (CSC60G-ND). Here is the part number of the round ones you were talking about SAM1119-32-ND. I agree that it is pretty stupid that you can get a 1x50 for a few bucks, and for about the same price you can get a 1x4.

    Another source of inexpensive connectors is Phoenix http://www.phoenixent.com/ . The only negative is they have a $50 minimum order. When I need parts from there I order a bunch of extra stuff and fill up my parts bins.

    I have found http://www.pololu.com/search?query=headers to be the best price.

    I agree with peter. I buy 1,000 pcs from 4ucon but be careful, their shipping always seems to be ~30% of the hardware cost, no matter the size or weight.

    Now I have some headers and sockets etc that I cut down and some smaller ones too. I am willing to sell and post in smaller units but not in small qties like 4. Even as a favour it is just too time consuming. I will post here later what I have and if anyone wants 50 of anything I have (and I will mark it up a little to cover my time etc) then they can let me know.

    The xtal pins (socket pins) I use are from digikey ED5037-ND

    Ya that all electronics place has a good selection of stuff thanks. Im really looking for like female headers though I guess there sip sockets will work or the digi ones. I didnt realize these things were all snapable thats probably why ive been having a hard time finding stuff. Im not trying to buy in alot of bulk right now I cant afford it. Basically at this exact moment Im trying to make 20 bucks strech to build 2 boards finished product type boards. Just need sockets xtals and headers and some decoupling caps. Like I said though I guess i just didnt think about cutting or snapping these things.

    If you were to buy a new dev board kind of thing how would you guys like the pins to accessible. I like the idea of male header and a dip style demo board which plugs into a bread but female sockets seem more convenient in reality. If anyone has a digikey part number for .1 female headers that break easily and are cheap id appreciate it. Im not sure weather people would rather work with the square ones or the sip kind. I think id prefer the higher profile square kind. Anyways the point is im limited here not alot of cash and id rather pay a lil more for good caps and get cheaper sockets. Im also trying to get some parts for my next project to so buying 10 dollars in bulk headers isnt gonna cut it.

    Thanks for the offer cluso, I will keep you in mind for the future though when I have some extra money.

    The male headers break apart easily. The female ones need the pin pulling and then you can cut with cutters and file to clean the ends. So, you lose 1 pin when you cut. Be careful, you can only put in 1 join in a strip because butting them is slightly longer. I mainly use female with longer pins - I can cut the pins off if I dont need them after soldering. This way I can use the same ones for stacking.

    Sparkfun appears to have some female headers at a low price... Not completely sure they're gold, but they look it...

    @clusso I think you may have exactly what id like but dunno where to obtain! Ideally I would like female headers next to the prop pins but id also like the the male pins directly under the male headers. This would give the user the option to either stack a shield or jumper wire from the top of the pcb, and then have male connections un der the pcb to let the user plug into breadboards or break out on a perfboard. And in th e ideal world I wou rld I would also supply a strip. Of female to female headers wich you would slide over the breadboard dip style comtacts when there not needed or u wanna plug the bottom male headers into a male interface. This is a very elegant solution and since all the break outs are lined up it keeps the pcb very compact! To me for 32 pins this system shouldn't run over 5 bucks a board. Excluding price can you give me some decent sources for these long strips of the female with long pin single row and female to female single row. 1 header/interconects? Also using male headers on bottom female on top but seperate parts in paralell row just adds that much more resistance on the data pins and 32 more solder points of my time since I'm going to hand etch, oh ya and more holes to drill :)

    Just a bit of caution, I looked at this subject the other night. There are "headers" and there are "receptacles". What I saw was headers are intended to receive square pins, mating to a male header. Receptacles have a spring finger and can accept square and round pins of various thickness. This subtle nuance can lead to a wasted purchase or intermittent functioning.

    EDIT: You want what they refer to as a stackable header, Sparkfun carries some for Arduino shields: http://www.sparkfun.com/products/9279

    Look at the 4uconn website. You will see all the headers there. My website has some photos of the connectors I use mounted on the pcbs. I have 1x9 female with long pins and 1 spacer. http://www.4uconnector.com/
