content: Searching the net has failed me. I have some decent crimpers and want to make some custom cables for standard .1" headers. These are the standard ones used for motherboard power LEDs, for Arduino headers, and so on.eBay sellers and other Chinese sources call these "Dupont" connectors for some unknown reason. But I already have some of those Chinese pins and sockets which are not the best quality. So I'd like to order some female and male pins from Digikey, but it turns out to be difficult to identify them.Are they the JST XH series like this?http://www.digikey.com/product-detail/en/jst-sales-america-inc/SXH-002T-P0.6/455-2261-1-ND/1651059The data sheet looks wrong, though.Digikey or manufacturer part numbers would be great.

content: When I needed 0.025" female push terminals for some Tek grabbers I found the only way to easily find them was by a pin measurement search.

content: .1" headers can be found (keyed) as molex KK series.they crimp pretty well with low-cost crimpers, such as these:https://www.amazon.com/gp/product/B017JU20Z6I use those for KK molex and it fits well enough that they look strong and have the 2 level crimp (insulation and wire) that I was hoping for.I think it will do the 'proper' dupont pins as well. I just use the KK's since lots of projects I work on spec out the KK and they are common for .1 spacing in DIY.

content: I've used these Harwin M20 as replacements for Molex KK (I think they were recommended by Farnell as suitable replacements and they are just fine) :https://uk.farnell.com/harwin/m20-1180046/contact-socket-30-22awg-crimp/dp/1022220(note price is for bag of 100 contacts)As for crimping tool, I'm using an Engineer PA-09 (or PA-20, i always mix them up, the one with dies for larger crimps) bought from eBay from an Irish importer.. but you can buy it directly from Japan or Amazon these days. They're good quality and cheap but there's better models (ratcheting for example, or ones that make both crimps simultaneously, or both), I needed something cheap and didn't care about crimping speed.

content: For completeness, can we add male pins? Harwin does not seem to have them, or maybe just Digikey does not have the Harwin ones.Maybe these?http://www.digikey.com/product-detail/en/amphenol-fci/75653-002LF/609-3659-1-ND/1488325orhttp://www.digikey.com/product-detail/en/te-connectivity-amp-connectors/5-102095-4/A33420CT-ND/1117914

content: The male "pins" are made the same way as the female terminals. They are simply folded metal. Sort of okay if you really need them, but they are relatively weak and flimsy. I found it better to standardize using male headers on boards and female in the wire housings.I use the Molex SL series. It has a wide variety of types and styles and looks good. KK looks cheap and ugly to me. C-Grid is a combination type, made to work with both SL and KK type and I have no use for that.If space permits I prefer the IDC type such as Tycho/AMP MTA series. They are quicker and easier to use.
