391-106-555-201

Edgeboard Connectors Overview

The EDAC Inc. 391-106-555-201 is a dual-sided card edge connector from the 391 series, designed for vertical board-edge mounting. It features 106 positions with a 0.100-inch (2.54mm) pitch and two rows of contacts. The connector utilizes copper alloy terminals with gold plating to ensure reliable signal transmission. It supports PCB thicknesses ranging from 0.054 inches to 0.070 inches (1.37mm to 1.78mm). The housing is constructed from black thermoplastic polyester, providing durability and insulation. Operating temperatures range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-sided contact configuration for high-density interconnect applications
• Vertical board-edge mounting style for secure PCB integration
• Gold-plated copper alloy terminals for enhanced conductivity and corrosion resistance
• Thermoplastic polyester housing for structural stability and thermal performance

Edgeboard Connectors Applications

• Industrial control systems requiring robust card-edge interfaces
• Communication equipment utilizing standard 0.100 inch pitch modules
• Consumer electronics assemblies needing reliable vertical connections
• Medical device hardware with strict environmental operating requirements

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required pin count and pitch specifications before ordering. Confirm compatibility with the target PCB thickness range to ensure proper mechanical fit. Check for RoHS compliance status if environmental regulations apply to the end product. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this connector when a dual-sided interface with a 0.100 inch pitch is required for vertical mounting. Consider the gold plating thickness for long-term reliability in harsh environments. Evaluate the thermoplastic polyester material properties against thermal and chemical exposure limits. Compare alternative series only if different mounting angles or contact counts are necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 391 series, which specializes in standard card edge connectors. The series offers various position counts and mounting styles to accommodate diverse electronic design needs. The 391 series is widely recognized for its consistent quality and broad availability across industrial and commercial sectors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variants with different pin counts such as 391-106-555-202 or 391-106-556-201, provided the mounting style and pitch remain identical. Cross-series replacements require careful verification of mechanical dimensions and electrical characteristics to ensure functional equivalence.
