Frequently Asked Questions

1. What is the difference between the BC-35-3P and BC-20-NP battery connector series?

The BC-35-3P series is a fixed 2-6 pin design rated at 2.0A / 12V with an LCP (UL94V-0) housing operating from -40°C to +85°C, optimized for standard SMT assembly. The BC-20-NP series is a high-durability multi-pin design rated at 3.0A / 50V with a heat-resistant PA9T housing (-55°C to +125°C), engineered to withstand 10,000+ mating cycles.

2. Are these PCB battery connectors compatible with SMT reflow soldering?

Yes. Both series use high-temperature housing materials—LCP (UL94V-0) for BC-35-3P and PA9T for BC-20-NP—that withstand standard lead-free reflow soldering peak temperatures. They are designed for automated pick-and-place assembly.

3. How do these connectors perform under vibration?

The resilient spring contact design, made from Phosphor Bronze or Brass (C2680) with selective gold plating (up to 30u”), maintains contact resistance at ≤30mΩ and ensures a steady connection even under mechanical shock and vibration.

4. What pin counts and configurations are available?

Available in 2P, 3P, 4P, 5P, and 6P configurations across both the Battery Contact Socket and Spring Contact Pin series. All variants use a 2.50mm pitch and support SMT/DIP mounting.

5. What are the rated current and voltage specifications?

BC-35-3P series: 2.0A / 12V DC. BC-20-NP series: 3.0A / 50V DC. Both series feature contact resistance ≤30mΩ and insulation resistance ≥500MΩ.

6. What materials are used for the housing and contacts?

Housing options: LCP (UL94V-0) for BC-35-3P and PA9T (high-temperature) for BC-20-NP. Contacts use Phosphor Bronze or Brass (C2680) with selective gold plating to prevent oxidation and maintain low resistance.

7. What is the operating temperature range?

BC-35-3P series: -40°C to +85°C. BC-20-NP series: -55°C to +125°C. The higher temperature range of the BC-20-NP makes it suitable for industrial and automotive-adjacent environments.

8. How many mating cycles can these connectors withstand?

The BC-20-NP series is rated for 10,000+ mating cycles thanks to its durable spring contact design and premium gold plating. The BC-35-3P also offers high cycle life suitable for consumer and medical devices.

9. Can I customize pin count, height, or plating thickness?

Yes. Full OEM/ODM customization is available including specific pin configurations (2P-6P), custom low-profile heights (DIM A/B options), and selective gold plating thicknesses to meet medical device or industrial equipment standards.

10. Do you provide technical drawings and samples?

Yes. Request PDF technical drawings and sample units by contacting our engineering team. We also offer bulk pricing for production volume orders. Email nick.xu@lyd123.com for qualification samples and project support.
