306-010-400-178

Edgeboard Connectors Overview

The EDAC Inc. model 306-010-400-178 is a dual-edge card edge connector designed for board-to-board or backplane applications. It features 20 total positions arranged in two rows of ten, with a 0.156-inch (3.96mm) contact pitch. The connector utilizes female cantilever contacts made from copper alloy, terminated via solder eyelets for secure PCB mounting. The insulator is green polyamide, rated for operation between -40°C and 105°C. This component supports non-specified dual-edge cards and provides reliable electrical interconnection.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever contact design for reliable card insertion
• Solder eyelet termination method ensures robust mechanical and electrical connection to the circuit board
• Green polyamide insulation material provides stability across a wide operating temperature range

Edgeboard Connectors Applications

• Industrial control systems requiring dual-edge card interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange configurations. Ensure compatibility with target card edge thickness specifications before procurement. Cross-reference manufacturer datasheets for precise mating force requirements and environmental ratings to validate suitability for the intended operational environment.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row, 0.156-inch pitch interface is required for non-specified dual-edge cards. Consider the solder eyelet termination for through-hole mounting processes. Evaluate the thermal rating of -40°C to 105°C against system operating conditions. Confirm that the green polyamide housing meets aesthetic or regulatory requirements for the final assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of card edge connectors, which are engineered for high-density interconnect solutions. The series offers various row counts and pitch options to accommodate diverse board layouts. The 306-010-400-178 variant specifically addresses applications needing twenty contacts in a dual arrangement, providing a standardized solution for modular electronic systems.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides for direct equivalents. Verify pin count, pitch, and termination style match exactly. Ensure replacement parts maintain identical thermal and electrical ratings.
