JST PH 2.0 mm Pitch 2-Pin/3-Pin/4-Pin JST Wiring Connecting IC Male Plugs, Female Sockets Housing and T-Shaped Crimp Terminal Kit. 150 Sets/750 Pi...

The right size and quality for a versatile connector. It saved me money

Accurate description, good price for a hard to find item

Pins are pretty cheap and not very uniform but sufficiently good for low amperage applications. You have to cut them off a strip of pins. Connectors are extremely basic but work well enough.

These crimps are not interchangable with some cheaper "XH" crimps I had from an all in one (crimper included) kit from ZeeBooth, but I think these are higher quality. They are easy to crimp and work well. I normally use an Iwiss IWS-2820M to crimp which is a very good tool, but I'm pretty sure even my cheaper ratcheting crimp tool worked ok on these. Highly recommend this seller for crimp connectors.

I have no fancy equipment to verify that these connector shells and contacts are within the allowed tolerances of the JST-XH specification, but what I can say is that the first 10 crimps I made - attaching female pins to 24 ga wire - went smoothly and flawlessly with an IWS-3220 crimp tool (1.6 mm slot). Insertion of the crimped contacts into this kit's 2 pin shells was easy. The goal was to shorten cables from 8" to 3.5" on five 4020 fans (2 wires each). The shortened cables all mated securely with existing circuit board JST-XH sockets, and the fans worked fine. For under $10 the cost of this approach (maximum $2 per cable, completely discounting the excess shells and pins included) was worth it to me. One caveat; if you don't already have a crimp tool you would have to include that cost along with potentially "wasted" consumables as you learn to use it. Fortunately the cost of many crimp tools has become quite reasonable, even for occasional use. Of course, with a project involving only 10 wires and contacts are cheaper solutions - such as keeping the existing cable end connectors, cutting out a section of the cables, and rejoining the wires with barrel crimps or perhaps solder with heat shrink insulation. However, with these methods the very short cables would not be very flexible, nor would they look very good, IMO. Several different crimp tools are available that accept these contacts. Fortunately the one I have (noted above) works well with the contacts in this kit. The other connectors included (i.e. the remaining 2 pin, as well as 3 and 4 pin ones) I won't use right now, but for the price it is like getting them for free, and I've no doubt that eventually I'll put them to use. They store nicely in the provided plastic box. Overall for my small job there were no problems at all, other than ensuring up front that I was ordering the right JST connector variant (-XH in this case) to match my existing components, so 5 stars.
