302-124-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-124-621-201 is a dual-edge 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 supports non-specified dual-edge cards within a thickness range of 0.051" to 0.071" (1.30mm to 1.80mm). Constructed with black polyamide (PA66) insulation and copper alloy terminals, it operates reliably between -55°C and 85°C. This component utilizes a solder termination method and is RoHS3 compliant.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with gold-plated contacts for reliable signal transmission
• Vertical staggered PCB mounting design optimized for space-constrained applications
• Robust construction using black PA66 insulation and copper alloy terminals
• Compliant with RoHS3 standards for environmental safety

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment utilizing standard dual-edge card formats
• Consumer electronics with vertical board stacking requirements
• Automotive electronic modules needing durable edge connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact finish and insulation material. Confirm compatibility with the target PCB layout regarding vertical staggered mounting dimensions. Ensure the selected quantity aligns with manufacturer standard packaging constraints. Check for updated compliance certifications such as RoHS3 status prior to final procurement approval.

Edgeboard Connectors Selection Notes

Select this connector when a high-pin-count solution with fine 1.27mm pitch is required. The dual-edge design accommodates thicker cards up to 1.80mm. Consider the vertical staggered mounting profile for PCB space optimization. Verify thermal operating limits against the application environment to ensure performance within the -55°C to 85°C range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series, which specializes in standard card edge connectors with 0.050" spacing. The series offers various pin counts and mounting options. The 302-124 variant provides a high-density solution suitable for complex circuit boards requiring robust mechanical retention and electrical stability in demanding environments.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 124-position count, 1.27mm pitch, and dual-edge female configuration. Verify identical vertical staggered mounting profiles and compatible card thickness ranges. Cross-reference insulation materials and contact finishes to ensure equivalent performance characteristics.
