302-124-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-124-321-201 is a standard card edge connector from the 302 Series, designed for vertical staggered PCB mounting. It features 124 positions with a 0.050" (1.27mm) contact spacing and gold-plated contacts. The connector is female, non-specified dual-edge type, utilizing copper alloy cantilever contacts. It supports board thicknesses of 0.051" to 0.071" (1.30mm to 1.80mm). The housing is black polyamide (PA66), rated for -55°C to 85°C operation, and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Vertical staggered PCB mounting configuration for space-efficient assembly
• Gold-plated copper alloy cantilever contacts ensuring reliable signal transmission
• Dual-edge female interface compatible with non-specified card edge boards
• Black polyamide (PA66) insulation providing thermal stability within specified range

Edgeboard Connectors Applications

• High-density electronic circuit board interconnections
• Industrial control system module integration
• Telecommunications equipment backplane connections
• Automotive electronics sub-system linking

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact plating and housing color specifications. Confirm that the staggered pin arrangement aligns with the target PCB footprint design. Ensure the selected quantity accounts for the manufacturer's standard packaging requirements. Cross-reference the RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, low-profile connection is required for dual-edge cards. The 0.050" pitch allows for dense I/O arrangements in constrained spaces. Consider the vertical staggered orientation for optimal board clearance and routing flexibility. Validate that the operating temperature range meets the environmental demands of the intended application scenario.

Edgeboard Connectors Part Context

This part belongs to EDAC’s 302 Series, which specializes in standard card edge connectors with fine 0.050" pitch. The series offers various position counts and mounting styles to support diverse board-to-board connectivity needs. The 302-124-321-201 specifically addresses applications requiring robust, high-density interfaces with reliable mechanical retention and electrical performance.

Edgeboard Connectors Replacement Considerations

Direct substitutes must maintain the 124-position count, 0.050" pitch, and vertical staggered mounting style. Verify compatibility with existing PCB footprints and card edge thickness tolerances. Ensure equivalent material properties for both the insulating housing and contact plating to preserve electrical and mechanical integrity.
