302-020-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-020-221-201 is a standard card edge connector from the 302 Series, designed for dual-edge board applications. It features 20 positions with female contacts arranged in two rows of ten. The connector utilizes a 0.050 inch (1.27mm) contact spacing and accepts card thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). Termination is achieved via soldering, and the contacts are gold-plated copper alloy cantilever springs housed in black polyamide insulation.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with cantilever spring contacts for reliable mating
• Gold-plated termination ensures corrosion resistance and low contact resistance
• Mounts directly onto the board edge using through-hole solder joints

Edgeboard Connectors Applications

• Interconnection for non-specified dual-edge circuit boards
• Extension board tail connections in modular electronic systems
• General-purpose signal routing in industrial control panels

Edgeboard Connectors Procurement Notes

Verify that the target PCB design accommodates the specific 0.050-inch pitch and dual-row layout. Confirm that the inserted card thickness falls within the specified 1.30mm to 1.80mm range to ensure proper mechanical engagement. Check for RoHS3 compliance requirements if operating in regulated environments. Ensure soldering profiles match the thermal limits of the polyamide housing and gold flash plating to prevent damage during assembly.

Edgeboard Connectors Selection Notes

Select this component when a compact, low-profile interconnect solution is required for thin dual-edge cards. The 302 series offers a balance of density and mechanical stability for vertical mounting. Consider the cantilever contact type for ease of insertion and removal compared to press-fit alternatives. Verify that the black polyamide housing meets the environmental temperature ratings required for the specific application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in standard card edge connectors with fine 0.050-inch spacing. The series is characterized by its use of cantilever contacts and thermoplastic housings, suitable for high-density applications where space is limited. The 302-020 variant specifically addresses needs for 20-position interfaces in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include other position counts such as 302-006-256-201 or 302-012-256-201, provided the pin count matches the design. Cross-series replacements like the 396 series offer different spacing and mounting styles and require careful mechanical verification.
