Frequently Asked Questions

1. What configurations are available for the 2.54mm female header?

This series is available in single row (1*2P to 1*40P) and dual row (2x2P to 2x40P) configurations, with both straight (vertical) and right-angle (horizontal) mounting options to accommodate various PCB layouts and stacking requirements.

2. What is the electrical rating?

The connector is rated for 3.0A current, 600V AC dielectric withstanding voltage per minute, and insulation resistance of 1000MΩ minimum. This makes it suitable for both signal-level and low-power interconnections in industrial and consumer electronics.

3. What insulator materials are available?

We offer multiple high-temperature thermoplastic options including PA6T, PA9T, and LCP (Liquid Crystal Polymer), all compatible with lead-free reflow soldering processes. Each material provides excellent dimensional stability and thermal resistance for automated assembly environments.

4. What is the dual-beam contact design?

The dual-beam contact design features two independent spring beams per contact position, providing redundant electrical connection points. This ensures reliable signal transmission even under vibration or shock, and offers higher contact normal force compared to single-beam designs.

5. What contact plating options are available?

Contact finish options include gold flash (1µ” to 30µ” gold plating) and tin plating. Gold plating is recommended for applications requiring high mating cycle counts or operating in corrosive environments, while tin plating offers a cost-effective solution for standard applications.

6. What is the operating temperature range?

The specific temperature range depends on the insulator material selected, with LCP offering the highest performance typically rated for -40°C to +150°C (suitable for lead-free reflow), while PA6T and PA9T also support high-temperature soldering processes common in modern PCB assembly.

7. What is the typical mating interface with male pin headers?

This female header mates with standard 0.64mm square pin headers commonly used in 2.54mm pitch board-to-board and wire-to-board applications. The dual-beam contacts provide a secure grip on the male pins while maintaining low insertion force for easy assembly.

8. Is this connector suitable for automated SMT assembly?

Yes. The connector is designed for automated pick-and-place assembly with optional Tape & Reel packaging. The high-temperature insulators (PA6T/PA9T/LCP) withstand lead-free reflow profiles, and the flat top surface provides stable vacuum pickup during placement.

9. Do you provide samples and technical drawings?

Yes. Request PDF technical drawings, 3D models, and detailed specifications using the form above (click “Download Specifications & Request a Quote”). Samples are available for evaluation. Our engineering team can also assist with footprint recommendations.

10. Can I get customized pin lengths or special packaging?

Yes. We support customized pin lengths, special plastic heights (e.g., 8.5mm, 5.0mm), and Tape & Reel packaging for automated assembly. Contact our sales team via the email below for custom specifications and bulk pricing.
