About

JST 2.54mm EI Series Connectors — Reliable Wire-to-Board Interconnects for General-Purpose Electronics The JST EI series at 2.54mm pitch delivers dependable wire-to-board connectivity in a compact, easy-to-assemble format. Built on the universally adopted 0.1-inch grid standard, EI series connectors integrate effortlessly into a wide range of PCB designs — from hobbyist development boards to professional embedded systems — offering consistent electrical performance and mechanical reliability across diverse application environments. Key Technical Advantages 2.54mm Universal Pitch: Fully compatible with the industry-standard 0.1-inch grid, enabling seamless integration with breadboards, Arduino-compatible layouts, and the vast majority of through-hole PCB footprints without custom design work. Friction-Lock Housing: Positive retention mechanism maintains secure mating under normal handling and vibration conditions, preventing accidental disconnection in portable and bench-top equipment. Tin-Plated Copper Alloy Contacts: Delivers stable, low contact resistance over extended service life with reliable performance across thousands of mating cycles in general-purpose signal and low-power applications. High-Temperature PA66 Housing: UL94 V-0 rated nylon housing rated for continuous operation up to 105°C, maintaining structural integrity and dielectric performance across typical operating temperature ranges. Wide Pin Count Range: Available from 2-pin to 12-pin configurations, supporting simple two-wire power connections through multi-channel signal harness assemblies. Wire Gauge Compatibility: Accepts 22–28 AWG wire, compatible with standard JST crimp tooling for clean, repeatable terminations in both prototype and production environments. RoHS & REACH Compliant: All materials meet current EU environmental directives, supporting global market access for finished products. Typical Applications Arduino, Raspberry Pi, and development board peripheral wiring Prototyping har
