302-100-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-100-321-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 100 positions with a 0.050 inch (1.27mm) contact spacing and utilizes gold-plated contacts on a copper alloy base. The connector supports PCB thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). It employs a through-hole mounting style with a black polyamide (PA66) insulator and operates within a temperature range of -55°C to +85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with 100 female contacts for secure signal transmission
• Gold flash plating on copper alloy contacts ensures reliable conductivity and corrosion resistance
• Polyamide (PA66) housing provides structural stability and thermal endurance
• Through-hole termination method facilitates robust mechanical attachment to printed circuit boards

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the specified 1.30mm to 1.80mm range to ensure proper contact engagement. Confirm that the design accommodates the 0.050 inch pitch and dual-edge orientation. Check for RoHS3 compliance requirements if environmental regulations apply to the final assembly. Ensure storage conditions maintain component integrity prior to soldering.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count interface is required for dual-sided card edge applications. The 1.27mm pitch offers a balance between density and manufacturability. Consider the through-hole mounting requirement for mechanical strength over surface mount alternatives. Verify that the operating temperature range meets the environmental demands of the specific deployment scenario.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series, which specializes in standard card edge connectors. The series is characterized by its versatile pin counts and consistent 0.050 inch spacing. The 302-100-321-201 variant specifically addresses needs for higher channel counts while maintaining the series' established reliability standards and material specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with different pin counts such as 302-012-321-201 or 302-100-321-202, provided the electrical and mechanical interfaces remain compatible. Cross-series replacements require careful verification of pitch, mounting style, and contact geometry to ensure functional equivalence.
