content: I am trying to find a reliable source of 24 pin 1x24 2.54mm/100mil pitch sockets. Would really appreciate any help.LCSC carries none. DigiKey and Mouser don't seem to carry anything but wildly expensive Samtec ones. I know they exist because a few suppliers have them though at moderately high prices. It will be part of a kit for mounting a 48 pin microcontroller module so I am trying to keep the cost down. I'm hoping to find them under $0.15 USD.There are a few aliexpress vendors that claim to have them but my experience with those types has been decidedly mixed. Would prefer to go through a real distributor for consistency - I want to be able to repeat an order and get the same thing. I did ask one US based supplier that has them (at $0.75) who their supplier is but, unsurprisingly, got no response.

content: You could use Arduino sockets, Digi-Key S7022. I use them on the CRAMPS board to plug 3 Pololu stepper drivers into.They are about $1 in modest quantity.Jon

content: Instead of getting one 24x1 socket you will probably have more luck finding a cheaper part if you use multiple <24P sockets. For example3pcs of 8x14pcs of 6x1...

content: Another company:http://www.tkp.com.tw/en/category/2.54mm-Board-to-Board-Series-Connector/TKP-C-02_54mm.htmlI don't know how well you will fare looking for presumably low quantity of these connectors, but worth a shot. Both put between 2 - 40 positions on their standard datasheets in increments of 1. Doesn't mean they actually make all of them or that they are stocked, but maybe their molds/tooling is already set up to accommodate.

content: Quote from: ANTALIFE on April 22, 2021, 03:29:32 amUsually they don't fit the equivalent larger socket, i.e. you cannot fit 3 8x1 into a 24x1 space. 8x1 x 3 is longer than 24x1

content: Quote from: phil from seattle on April 26, 2021, 03:17:36 pmWell, you might be able to find these somewhere in China for $0.15, but certainly not in the US. If you need a whole bunch of them, you might be able to buy direct from the manufacturer. I buy some 2-part screw terminal connectors from a manufacturer's rep for HALF the Digi-Key price. I only need to buy in 50-piece quantity to get the better price. BUT, I need to order 8 - 12 weeks in advance.Jon

content: It depends on the quantity you need. If you can buy 1,000 the best option is 4uconnector. Even if you pay express shipping you can buy them at a fraction of the retail price, but you need to wait 4-8 weeks as they don't stock in advance. I have been using them for 10 years, very reliable manufacturer.

content: You could buy anything bigger than 24 and just cut it down to 24 pin ... i used nail clippers in the past for quick and easy cutting.You could use one of those rotating polishing tool to quickly polish / remove a bit of plastic from the end of connectors if you want to combine 2 x 12 or 3 x 8 or 2 x 10 + 1 x 4Alternatively, maybe you could redesign your board to have the pins in 2 rows (unless it's some hat for a pi or arduino, forcing you to keep it 1 row)

content: If you specify the request then maybe you get a better help, ok I know that you mentioned the size 24x1 and the footprint spacing 2.54mm this will orient all the users to suggest you to use a bigger socket and cut it out or to combine small sockets until you get the needed size.If you have some limitations on your design you need to mention this otherwise i don't see any problem from combining multiple suckets.about suppliers, have you searched for this socket on Amazon or Ebay, I know, not the appropriate place to look for electronics stuff but since you don't have many options then you can give it a tryI buy all my parts from Farnell and I recommend it for you

content: I think you have prematurely ruled out AliExpress. They're perfect for this sort of thing. And the prices you will likely see make it worth an occasional misfire. Though I don't expect you'll get a misfire.

content: Quote from: DIYGUY Chris on May 02, 2021, 12:28:26 amAs was discussed earlier, multiple sockets like 2 12x1 don't work together because they are slightly longer than 12 times 2.54mm.Cutting several hundred sockets from longer ones does not work for me.

content: Quote from: phil from seattle on May 02, 2021, 12:49:31 amCan you elaborate why not? We produce tens of thousands of boards per year, most with at least one pin header. For the most part the team just snip apart 40 pin headers using a pair of cutters.Edit:we do the same with header sockets too; they just get cut apart and the cut edge left as-is. I've never had any complaint about the aesthetics of it but I accept it would be less than ideal for some specific applications.

content: Quote from: Mangozac on May 02, 2021, 11:23:35 pmBreaking apart snappable headers is one thing. The kid of sockets I want to use don't come in snappable lengths. So, I'd have to cut them apart and sand or grind the edges to make them smooth and professional looking. Way too much time.

content: Quote from: phil from seattle on May 02, 2021, 11:55:47 pmSorry, I wrote my comment in a rush and didn't describe fully. We do this for both header pins and the mating header sockets and with a correct jig to set the length it's really not time consuming for a worker to cut them with cutters. So long as you're not worried about the finish (which we've never had any issues with).Still, great to hear you've found a source for the correct length

content: I posted a link to parts found on AliExpress, IIRC they were $0.20 each or less. Unfortunately, it was lost with the data roll back.If you’re still looking, let me know and I’ll look again. Cannot remember the search string but once you work out the translation, they appeared to be fairly common and dirt cheap.Edit. Found them. Good seller rating at $0.125 each.https://www.aliexpress.com/item/1005001418544370.html

content: Can you post a datasheet of the exact component you are after? We know of many manufacturers in Asia that can supply this item. However, you will need to define the height of the plastic insulator; the pin length for the solder tail; the plating of the solder tail; the depth of the pins inside the plastic insulator so that the mating male pin does not interfere with the female, etc.We have one favorite manufacturer in Shenzhen we can suggest but want to be sure we are talking about the same item. For us, we prototyped with Samtec who makes great and solid parts but for live builds, there were just too expensive. Shifted to Asia for the volume buys. As the parts are rather inexpensive, most likely you will have to purchase in 1k lots (or whatever the vendor states as their MOQ).

content: Thanks for the kind offer. I do appreciate it.I have found an Aliexpress vendor (the one discussed above) that has reasonable quality & quantity at a reasonable price. I don't know how long they will be around and will be checking any follow on order closely but, for now, problem solved.
