A range of Series 171856 and 17857 KK 254 Reflow Process Compatible (RPC) Vertical and Right Angle Friction Lock Headers from Molex. These KK 254 RPC Headers are capable of withstanding up to 260 °C solder processes. This range of KK 254 Reflow Process Compatible (RCP) Friction Lock Headers have Matte-tin over Nickel plated contacts which inhibits Tin whiskering. The Series 171856-3xxx and 171857-3xxx KK 254 RPC Headers have a High Temperature Thermoplastic (Polyester) body material which is UL 94V-1 rated.

For mating KK 254 wire socket housings see stock numbers 670-2825 typical and PCB sockets 296-5072 typical.

Make a connection you can rely on with this pin header from Molex. As it has two male pin connectors set at a right angle to the main body, you can use it to form a connection between two PCBs horizontally. Installation is simple via the through-hole mounting method. All you need to do is push the pins into holes drilled in the PCB and then solder them in.
