Molex KK2510 2.5mm DIP Header Connector Kit — 2P–12P, PCB Through-Hole

Molex KK2510 2.5mm DIP Header Connector Kit — 2P–12P, PCB Through-Hole, Complete Assortment

The Molex KK2510 2.5mm DIP header connector kit is the complete assortment of PCB through-hole KK2510 male headers for Arduino projects, 3D printers, industrial PCB wiring, and general-purpose electronics. This kit includes KK2510 DIP headers across all common pin counts from 2P to 12P — everything you need to populate PCBs with KK2510 headers for mating with KK2510 / KF2510 locking cable connectors.

The KK2510 / KF2510 2.5mm connector system is the widely-used standard for Arduino GPIO headers, 3D printer wiring, and industrial PCB connections — 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

• KK2510 2.5mm DIP through-hole headers — PCB solder-in mounting for permanent, robust connections
• 2P to 12P assortment — all common pin counts in a single kit
• Compatible with KK2510 / KF2510 locking cable connectors — mates with all KF2510 and KK2510 cable assemblies
• Positive-lock latch mating — cable connectors lock securely; prevents accidental disconnection
• Standard 2.5mm pitch — compatible with Arduino GPIO headers and standard PCB layouts
• RoHS compliant

Typical Applications

• Arduino shield and module PCB population — solder KK2510 headers onto Arduino shields and custom PCBs
• 3D printer PCB wiring — stepper motor driver, heated bed, and thermistor header population
