DJ212A-2.3A / DJ222A-2.3A Automotive 2.3mm Brass Wiring Terminal — Tin-Plated Male & Female Round Pin
The DJ212A-2.3A (male round pin) and DJ222A-2.3A (female round socket) are 2.3mm pitch brass automotive wiring terminals with tin plating, designed for use with DJ series automotive connector housings. The round pin/socket design provides 360° contact surface area for lower contact resistance and better vibration resistance compared to flat-blade terminals — making them preferred for high-reliability sensor and actuator circuits. Brass construction delivers superior corrosion resistance for long-term reliability in underhood and chassis environments.

Frequently Asked Questions
Q: What connector housings are compatible with DJ212A-2.3A / DJ222A-2.3A?
These terminals are designed for DJ series automotive connector housings with 2.3mm round pin cavities. The DJ series is a Chinese OEM standard widely used in domestic vehicle brands (SAIC, FAW, Dongfeng, Chery, Geely, BYD) and some export vehicles. Verify the housing cavity diameter matches the 2.3mm terminal before ordering.
Q: Why use brass instead of copper alloy for these terminals?
Brass (copper-zinc alloy) offers better corrosion resistance and higher mechanical strength than pure copper alloy. For round pin terminals that rely on spring contact force for electrical connection, brass maintains its spring properties better over thermal cycling and aging — preventing the contact loosening that causes intermittent faults in aging wiring harnesses.
