333-020-559-102

Edgeboard Connectors Overview

The EDAC Inc. 333-020-559-102 is a standard card edge connector from the 333 Series, designed for single-edge board applications. It features 20 positions with a 0.156" (3.96mm) contact pitch and accepts PCB thicknesses between 0.054" and 0.070" (1.37mm - 1.78mm). The connector utilizes female copper alloy contacts with gold plating, rated for 3A current. It employs a through-hole termination method with PC pins and is housed in green thermoplastic polyester. The unit operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Single-edge female configuration with 20 positions
• Gold-plated copper alloy contacts for reliable signal transmission
• Through-hole mounting with vertical orientation
• Green thermoplastic polyester insulation housing

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Communication equipment backplanes

• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure correct flange and pin configuration. Confirm that the target PCB thickness falls within the specified 1.37mm to 1.78mm range for proper mechanical engagement. Check RoHS compliance status if required by project specifications. Ensure the single-edge design matches the mating card geometry before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 20-position interface is required for vertical board-to-board or board-to-backplane connections. The 0.156" pitch accommodates standard density layouts. Consider the through-hole termination for high mechanical stability compared to surface mount alternatives. Verify that the operating temperature range meets the environmental demands of the intended application zone.

Edgeboard Connectors Part Context

This part belongs to the EDAC 333 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series offers multiple position counts and configurations to support diverse connectivity needs across industrial and commercial sectors. The 333-020 variant specifically addresses requirements for moderate density single-edge connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 20-position count, 0.156" pitch, and single-edge female configuration. Verify identical flange characteristics and termination style to ensure mechanical compatibility without redesigning the PCB footprint.
