Some of these (particularly for PH/XH) are frequently seen on eBay second hand, and may be worth watching out for if you crimp a lot of these connectors, as they are an order of magnitude easier to use than even the best generic tools.įor more obscure types, no hand tool is offered, however JST do sell a hand frame (YRS-XXX) for mounting dies for their MKS-L applicator (used in the AP-K2N crimping machine), a very expensive solution, and the only option for production/mission critical applications. I have listed the part numbers for these where available. These are mostly made by the German contract crimp tool manufacturer Wezag GmbH, will crimp the associated contacts perfectly and to specification, but are all expensive. JST offer high quality hand crimp tools for their popular connector families. Most will find it more convenient to source from eBay, however note that this is an unlikely source of genuine parts. ![]() Most are stocked by Digi-Key (US) and Farnell (UK). Where I specify part numbers, I’m only doing so for genuine parts. Note that compatible connectors are made by other manufacturers. Many of which are referred to as “JST Connectors” in various circles. On this page I’ll cover the most popular connectors from Japan Solderless Terminal. In the vernacular sense, precisely which type of connector is being referred to depends on who is using the term and in what context. Retrieved 13 August 2015.“JST Connector” is either shorthand for a connector manufacturer called Japan Solderless Terminal, or a vernacular term for a range of different type of wire to board connectors, which either are, or resemble designs from Japan Solderless Terminal.

To minimize confusion, it is best to describe a connector using: the manufacturer's name, exact connector series, and optionally the pitch, such as "JST-XH" or "JST-XH-2.50mm" or "2.50mm JST XH-series" or other variations. It is very common in blogs and websites to incorrectly name a specific connector only by the name of the manufacturer. Connector confusion on the internet Įnd-users and 3rd-party sellers on eBay often describe connectors by their wrong name thus perpetuating confusion of the exact series of a specific connector. Some JST surface-mount headers are designed to handle higher temperatures of reflow soldering. Used in some RGB LED decorative light strips.Ī majority of JST through-hole headers can't withstand the temperatures required for reflow soldering, because the plastic has a lower melting point since they were designed for wave soldering methods. ![]() The PCB (wire-to-board) connectors are available in top (vertical) or side (horizontal) entry, and through-hole or surface-mount. JST manufactures a large number of series (families) of connectors. ![]() The term "JST" is sometimes incorrectly used as a vernacular term meaning any small white electrical connector mounted on PCBs. JST connectors are used in many types of products, and commonly used by electronics hobbyists and consumer products for rechargeable battery packs, battery balancers, battery eliminator circuits, 3D printers, and radio controlled servos. JST manufactures numerous series (families) and pitches (pin-to-pin distance) of connectors. JST connectors are electrical connectors manufactured to the design standards originally developed by J.S.T.
