Overview
The Preci-Dip 450-V3-218-00-106101 is a board-to-board header connector from the 450 series. It features 18 positions with a 2.54mm pitch and two rows of male pins. Designed for surface mount installation, it utilizes solder tail termination. The contacts are made of brass with tin plating on both the mating and tail sections. The housing is constructed from glass-filled polyester, rated UL94 V-0, and is black in color. Electrical ratings include 3A current and 150VDC voltage.
Feature Summary
- Dual-row surface mount configuration for compact board-to-board interconnection
- Solder tail termination method ensuring secure PCB mounting
- Glass-filled polyester insulation providing structural stability and flame resistance
Applications
- High-density electronic assemblies requiring vertical board stacking
- Industrial control systems utilizing surface mount technology
- Communication equipment internal interconnects
Procurement Notes
Verify the specific suffix codes against official Preci-Dip documentation to confirm exact pin count, row configuration, and plating specifications. Ensure compatibility with automated surface mount assembly processes. Confirm that the tin-plated contacts meet the required corrosion resistance standards for the intended operating environment. Cross-reference the UL94 V-0 rating with project safety requirements.
Selection Notes
Select this component when a dual-row, surface-mount header with a 2.54mm pitch is required. The 18-position layout suits applications needing moderate I/O density in a small footprint. The solder tail design facilitates reflow soldering. Consider the 3A current rating and 150VDC voltage limit to ensure they align with circuit operational parameters. Verify mechanical clearance for the specified insulation height.
Part Context
This part belongs to the Preci-Dip 450 series, which specializes in high-reliability board-to-board connectors. The series offers various configurations including single and double rows with different termination styles. The 450 series is engineered for robust performance in demanding environments, featuring durable materials and precise contact alignment mechanisms suitable for automated manufacturing.
Replacement Considerations
Consult Preci-Dip catalogs for direct substitutes within the 450 series matching identical pin counts and row configurations. Verify cross-compatibility with other manufacturers' 2.54mm pitch headers only if mechanical dimensions and electrical ratings are strictly equivalent.
