302-120-656-201

Edgeboard Connectors Overview

The EDAC Inc. 302-120-656-201 is a standard card edge connector from the 302 Series, designed for high-density interconnection applications. It features 120 positions arranged in a dual-row configuration with a contact spacing of 0.050 inches (1.27mm). The connector utilizes gold-plated contacts and is rated for a board thickness range of 0.051 to 0.071 inches (1.30mm to 1.80mm). This component supports vertical mounting and provides reliable signal transmission through its robust copper alloy contact structure.

Edgeboard Connectors Feature Summary

• Dual-row formation with 120 total positions for high-density circuit board integration
• Gold-plated contacts ensure reliable electrical performance and corrosion resistance
• Compatible with standard card edge boards within specified thickness tolerances
• Vertical mounting style facilitates efficient PCB layout and assembly

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment interfaces
• Computing hardware peripheral connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating and housing material specifications. Ensure compatibility with the target PCB board thickness range of 1.30mm to 1.80mm. Confirm that the dual-row configuration aligns with the design requirements for the intended application environment.

Edgeboard Connectors Selection Notes

Select this model when a high pin count interface is required within a compact footprint. The 1.27mm pitch allows for significant I/O density compared to larger spacing alternatives. Consider the vertical mounting orientation for space-constrained designs where board-to-board or card-edge connectivity is necessary without requiring additional height clearance.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 Series, which specializes in standard card edge connectors. The series offers various position counts and configurations to suit different density requirements. The 302-120 variant represents a high-pin-count option within this family, providing extensive connectivity options for complex electronic assemblies while maintaining standard mechanical dimensions.

Edgeboard Connectors Replacement Considerations

Consult the official EDAC 302 Series cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the same 120-position count, dual-row layout, and 1.27mm pitch. Verify that alternative components support the same board thickness range and mounting style to guarantee mechanical and electrical compatibility.
