Molex KK 254 2.54mm DIP Header Connector Kit — MX5264 Compatible, 2–12 Pin

Molex KK 254 / MX5264 2.54mm DIP Header Connector Kit — 2–12 Pin, PCB Through-Hole, Complete Assortment

The Molex KK 254 / MX5264 2.54mm DIP header connector kit is the complete assortment of PCB through-hole KK 254 / MX5264 male headers for Arduino projects, 3D printers, PC fan wiring, industrial PCB assembly, and general-purpose electronics. This kit includes MX5264-compatible DIP headers across all common pin counts from 2 to 12 — everything you need to populate PCBs with KK 254 locking headers for mating with KK 254 / MX5264 locking cable connectors.

The KK 254 / MX5264 2.54mm connector system is the industry standard for Arduino GPIO headers, PC fan connectors, and general-purpose PCB wiring — offering a positive-lock latch that prevents accidental disconnection, unlike standard 2.54mm DuPont headers. With PCB through-hole mounting, these headers provide robust, solder-in connections for permanent PCB installations.

Key Features

• KK 254 / MX5264 2.54mm DIP through-hole headers — PCB solder-in mounting for permanent, robust connections
• 2 to 12 pin assortment — all common pin counts in a single kit
• Compatible with KK 254 / MX5264 locking cable connectors — mates with all KK 254 and MX5264 cable assemblies
• Positive-lock latch mating — cable connectors lock securely; prevents accidental disconnection
• Standard 2.54mm pitch — compatible with Arduino GPIO headers and standard PCB layouts
• RoHS compliant

Typical Applications

• Arduino shield and module PCB population — solder KK 254 headers onto Arduino shields and custom PCBs
• 3D printer PCB wiring — stepper motor driver, heated bed, and thermistor header population
• PC fan and cooling system PCB assembly — fan header population for custom PC builds
• Industrial PCB assembly — PLC I/O module and sensor connection header population
• Custom PCB design — populate custom PCBs with KK 254 headers for locking cable connections
