302-100-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-100-621-201 is a standard card edge connector from the 302 Series, designed for dual-edge non-specified cards. It features 100 positions arranged in two rows with a 0.050 inch (1.27mm) contact spacing. The connector utilizes female contacts with gold flash plating over copper alloy, housed in black polyamide (PA66). It supports board thicknesses between 0.051 and 0.071 inches (1.30 to 1.80mm) and employs a cantilever contact type for secure mating.

Edgeboard Connectors Feature Summary

• Dual-row configuration with 100 total positions for high-density interconnect applications
• Gold flash plated cantilever contacts ensure reliable signal transmission and durability
• Black polyamide housing provides structural integrity and thermal resistance
• Designed for non-specified dual-edge card insertion without mounting lugs

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interfaces
• Medical device internal connections
• Consumer electronics motherboard expansion slots

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact finish and housing color. Confirm that the target PCB design accommodates the 0.050 inch pitch and dual-edge card thickness range of 1.30 to 1.80mm. Ensure compliance with RoHS3 standards if environmental regulations apply to the final assembly. Check lead times as manufacturing schedules may vary based on production volume.

Edgeboard Connectors Selection Notes

Select this component when a 100-position dual-edge interface is required with a 1.27mm pitch. The gold flash finish is suitable for low-to-medium current applications requiring corrosion resistance. Consider the lack of mounting lugs for designs relying on board retention or external fixtures. Verify compatibility with the specific card edge geometry and thickness constraints of the host system.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in standard card edge connectors. The series offers various position counts and spacing options, catering to diverse electronic interconnect needs. The 302-100-621-201 specifically addresses high-pin-count requirements within the 0.050 inch spacing category, providing a robust solution for dual-sided card connections.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 Series parts with identical 100-position dual-row configurations and 0.050 inch spacing. Cross-referencing with generic card edge connectors requires verifying pitch, row count, and contact plating specifications to ensure mechanical and electrical compatibility.
