302-004-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-004-321-201 is a female edgeboard connector from the 302 Series, designed for dual-edge card applications. It features 4 positions with a 0.050 inch (1.27mm) contact spacing and supports board thicknesses between 0.051 and 0.071 inches. The connector utilizes gold-plated copper alloy contacts with a cantilever design, housed in a black polyamide (PA66) insulator. It employs a surface mount termination method and operates within a temperature range of -55°C to 85°C.

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact plating and termination type. Confirm the package quantity aligns with production needs, as standard packaging may vary. Ensure compatibility with the target PCB footprint and mounting constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge connector with fine pitch is required. The 0.050-inch spacing allows for high density in limited spaces. Verify that the target card thickness falls within the specified 0.051 to 0.071-inch range for proper contact retention.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in high-density edge connectors. The series offers various pin counts and termination options, making it suitable for diverse electronic applications requiring robust signal transmission in compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 0.050-inch pitch, 4-position count, and dual-edge female configuration. Verify that any alternative maintains the same surface mount termination and contact material specifications to ensure mechanical and electrical compatibility.
