2.54mm Pitch Single-Row Pin Header Connector (8.5H Vertical), Gold-Plated PCB Electronic Signal Terminal Connector with Custom Pin Configuration

This 2.54mm pitch single-row pin header connector is designed for stable PCB signal and power transmission. Featuring an 8.5H vertical through-hole structure and a customizable pin layout (with the 4th pin intentionally left empty), it supports flexible circuit design requirements for modern electronic assemblies.

The terminals are made from high-strength Brass C2680, plated with 50µ” nickel and 15µ” gold, delivering excellent corrosion resistance, stable conductivity, and long-term reliability. The UL94-V0 PA9T housing withstands high reflow temperatures while ensuring dimensional accuracy and insulation performance.

With a 3A current rating, 250V DC voltage rating, and a wide operating range from –25°C to +105°C, this connector is suitable for demanding environments. Mechanical retention reaches 1.0 Kgf before reflow, ensuring secure assembly even under vibration.

Ideal for signal, power, automotive electronics, industrial control systems, and high-performance PCB designs.

⚠️ Notes

• Ensure Correct Pin Alignment: Check orientation and positioning before mating to avoid mis-insertion, bent pins, or PCB pad damage.
• Do Not Exceed Electrical Ratings: Follow the specified current and voltage limits to prevent overheating or contact failure.
• Proper Insertion and Extraction Force: Avoid excessive force during mating/unmating to prevent deformation, cracked solder joints, or pin damage.
• Keep Contact Surfaces Clean: Ensure terminals remain free from dust, oil, oxidation, or contaminants that reduce conductivity.
• Follow Recommended Soldering Conditions: Use appropriate soldering temperature profiles according to plastic materials such as LCP, PA6T, PA66, or PBT.
• Verify PCB Hole Tolerance: Incorrect hole size may cause inadequate solder filling or mechanical instability.
• Avoid Mechanical Stress After Assembly: Do not apply lateral pressure or bending forces, especially for SMT pin headers.
• Maintain Proper Storage Conditions: Store in a dry, dust-free environment to prevent terminal oxidation; use anti-static packaging if required.
• Confirm Compatibility with Female Header: Ensure matching pitch, pin count, height, and contact design to avoid mating failure.
• Choose Correct Plating Specification: Select proper plating (gold, tin, nickel) based on your application’s durability, corrosion resistance, and signal reliability needs.
