306-020-400-158

Edgeboard Connectors Overview

The EDAC Inc. 306-020-400-158 is a standard card edge connector from the 306 series, designed for dual-edge board applications. It features 40 positions with a female contact type and a 0.156-inch (3.96 mm) pitch. The connector utilizes tin-plated contacts on a copper alloy base, housed in a green polyamide insulator. It supports PCB thicknesses of approximately 0.062 inches (1.57 mm) and operates within a temperature range of -55°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board retention
• Tin-plated contacts ensure reliable electrical conductivity
• Low-profile insulator body minimizes vertical space requirements
• Vertical mounting style facilitates standard panel integration

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Medical device internal circuitry connections
• Consumer electronics motherboard interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and insulation color. Confirm the PCB thickness tolerance aligns with the connector's acceptance range. Ensure the dual-edge design is compatible with the target board layout. Check for RoHS compliance documentation if required by project specifications. Validate pin count and pitch against schematic requirements before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge solution is required for 0.156-inch pitch applications. Consider the tin plating for cost-effective general-purpose use rather than high-corrosion environments. Evaluate the vertical mounting orientation against available panel space. Compare against the 302 or 357 series if different pitches or single-edge configurations are needed. Ensure the 40-position capacity meets the signal routing requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and plating options to suit diverse interconnect needs. The 306 series is characterized by its robust construction and compatibility with standard PCB manufacturing processes. It serves as a reliable interface between flexible circuits and rigid boards in compact assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 306 series parts with matching 40-position counts and 0.156-inch pitch. Verify compatibility with alternative manufacturers offering identical dual-edge female specifications. Ensure replacement parts maintain the same vertical mounting angle and PCB thickness tolerance. Cross-reference pinout definitions if the application requires specific signal assignments.
