KK® Reflow Process Compatible (RPC) connector system

Molex’s KK® connector system can be designed into a variety of power and signal applications and is available in industry-standard 2.54 and 3.96 mm pitch sizes. The KK connector product family comes in single-row, wire-to-board and board-to-board application and is cost-effective and versatile. KK® RPC headers are available in signal and power families and can handle solder temperatures up to 260°C. Customizable KK headers allow for more polarization options and design configurations, which makes the KK® connector system ideal for a variety of industries.

KK® 254 Connector System

Ideal for board-to-board and wire-to-board low-power and signal applications, KK® 254 connectors provide a flexible design and cost-saving solutions for a variety of applications

Signal application KK® 254 connectors are ideal for use in industries such as automotive, medical and consumer, delivering up to 5.0A and 250V per circuit in a 2.54mm centerline pitch. Dual-cantilever terminals offer a square-post contact area that interfaces with the male pin header through a spring-like contact. Available in 22 to 30 AWG wire, an optional box-style dual-cantilevered terminal is optimal for high-vibration applications.

Headers are available in single-row, unshrouded, through-hole PCB termination styles in solid and breakaway varieties. A friction lock is available for a more secure mating interface. KK 254 PCB receptacles are available in right-angle, top-entry and board-through configurations. Housings have built-in polarization features and are available in UL 94V-2 and UL 94V-0 nylons.

KK® 396 Connector System

Delivering 13.0A and 600V per circuit in an industry-standard 3.96mm pitch, power application KK® 396 connectors are ideal for low- to mid-power wire-to-board and board-to-board applications

Power application KK® 396 connectors are ideal for use in industries such as automotive, medical and consumer. Dual-cantilever terminals offer a square-post contact area that interfaces with the male pin header through a spring-like contact. Available in 18 to 24 AWG wire, anti-fishing options are available to protect the wire during cable assembly.

MarKK™ terminals are used to provide a high-force interface, ensuring a solid-performing contact for power applications up to 13.0A and 600V per circuit. KK 396 headers are available in single-row, unshrouded through-hole PCB termination styles in solid and breakaway varieties. A friction lock is available for a more secure mating interface and kinked PC tails ensure contact with the PCB during solder processing.

KK 396 PCB receptacles are available in right-angle, top-entry and board-through configurations. Housings have built-in polarization features and are available in UL 94V-2 and UL 94V-0 nylons.

Features and benefits include:

  • High-temperature nylon housing that withstands lead-free high-temperature solder processing up to +260°C and does not require the drying needs of normal nylon.
  • Optional box-style dual-cantilever terminal, which is ideal for high-vibration environments.
  • Polarized friction-lock header that prevents mismating.
  • Standard KK header footprint, which allows for drop-in replacement on existing header applications. Mates with standard KK receptacles.
  • Matte-tin over nickel plating, which inhibits tin whiskering.
  • PCB receptacles are available in standard KK connectors that ensure secure mating between headers and receptacles.
  • Tape-and-reel packaging with pick-and-place caps are available that enable highly automated termination processing and accurate PCB placement.
