Dual row connectors price

The price is primarily driven by pitch size (e.g., 1.27mm, 2.0mm, 2.54mm), contact plating material, and housing plastic type. Gold plating (measured in micro-inches) offers superior conductivity and oxidation resistance but increases cost compared to tin plating. Additionally, high-temperature plastics like LCP (Liquid Crystal Polymer), required for SMT (Surface Mount Technology) reflow soldering, are more expensive than standard PBT plastics used for wave soldering.

Connectors designed for high-current applications or high-speed data transmission require specialized alloys and precision engineering, leading to higher unit prices. You must verify the Current Rating (Amps) and Dielectric Withstanding Voltage. Over-specifying these parameters can lead to unnecessary costs, while under-specifying risks system failure or fire hazards.

For international trade, ensure the products are RoHS (Restriction of Hazardous Substances) and REACH compliant to avoid customs seizures in the EU and US. For industrial or consumer electronics, UL (Underwriters Laboratories) certification is a critical quality indicator that can justify a higher price point due to the rigorous safety testing involved.

While Through-Hole Technology (THT) connectors are often cheaper per unit, Surface Mount Technology (SMT) dual row connectors allow for automated pick-and-place assembly, which significantly reduces long-term labor costs and increases PCB density. When sourcing, consider the Total Cost of Ownership (TCO) rather than just the individual component price.

Always request a Material Safety Data Sheet (MSDS) and a Certificate of Compliance (CoC). When sourcing via Made-in-China.com, prioritize Audited Suppliers who have undergone third-party onsite inspections by companies like SGS or TÜV Rheinland. Requesting a pre-shipment sample for lab testing (X-ray fluorescence for plating thickness) is highly recommended for large-scale orders.

Negotiate based on Annual Forecasted Volume rather than individual POs to secure Tiered Pricing. Suppliers are more likely to offer a 10-20% discount if you commit to a long-term partnership. Additionally, discuss packaging options; switching from Tape and Reel to Bulk or Tube packaging can reduce costs if your assembly process is manual.

Dual row connectors have fragile pins that are easily bent. Ensure the contract specifies anti-static (ESD) packaging and vacuum-sealed moisture barrier bags. For shipping to international destinations, use FOB (Free On Board) terms to maintain control over the freight forwarder and ensure the cargo is handled as 'Fragile Electronic Components' to prevent mechanical deformation during transit.

Be aware of HS Code classification (typically under 8536.90). Check for anti-dumping duties or specific trade tariffs (like Section 301 in the US) that apply to electronic components from China. Utilizing Made-in-China.com's secured payment services can also provide a layer of transaction security, ensuring funds are only released once shipping documents are verified.
