302-020-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-020-321-201 is a standard card edge connector from the 302 Series, designed for dual-edge board applications. It features 20 positions with a female contact type and a 0.050 inch (1.27mm) pitch. The contacts are gold-plated copper alloy cantilever springs, housed in black polyamide (PA66). This component supports through-hole termination and is rated for operation between -55°C and +85°C.

Edgeboard Connectors Feature Summary

• Dual-edge configuration with cantilever spring contacts for reliable insertion
• Gold-plated terminals to ensure low contact resistance and corrosion resistance
• Black polyamide housing providing thermal stability and mechanical support

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects
• Telecommunications equipment backplanes
• Consumer electronics motherboards
• Automotive electronic modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact length and housing style. Confirm that the dual-edge specification aligns with the target PCB design. Ensure compliance with RoHS3 directives if environmental regulations apply to the final assembly. Cross-reference the manufacturer part number against authorized distributor lists to guarantee authenticity.

Edgeboard Connectors Selection Notes

Select this model when a 1.27mm pitch dual-edge connector is required. Consider the 20-position count for circuit density needs. Evaluate the -55°C to +85°C temperature range against operational environments. Compare against single-edge alternatives if board access constraints exist. Verify mounting requirements as this series typically lacks integrated lugs.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 Series, which specializes in high-reliability card edge connectors. The series offers various position counts and contact configurations. It is widely used in industries demanding stable electrical connections for removable circuit boards. The design emphasizes durability and consistent signal integrity across repeated mating cycles.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 Series variants with matching pin counts and pitch. Check cross-reference databases for equivalent connectors from manufacturers like Molex or TE Connectivity. Ensure dimensional compatibility and electrical ratings match before substitution.
