302-120-621-201

Edgeboard Connectors Overview

The EDAC Inc. 302-120-621-201 is a standard card edge connector from the 302 Series, designed for dual-edge PCB applications. It features 120 positions arranged in two rows with a 0.050" (1.27mm) contact pitch. The connector utilizes female, cantilever contacts with gold flash plating over copper alloy substrates. It supports board thicknesses ranging from 0.051" to 0.071" (1.30mm to 1.80mm). The housing is constructed from black polyamide (PA66) and employs a through-hole solder termination method. Operating temperature ranges from -55°C to 85°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration with cantilever spring-contact design for reliable insertion
• Gold flash plated contacts ensure corrosion resistance and low contact impedance
• Black polyamide insulation provides thermal stability and mechanical strength
• Through-hole mounting facilitates secure attachment to target circuit boards

Edgeboard Connectors Applications

• High-density electronic interconnect systems
• Industrial control and automation equipment
• Telecommunications infrastructure modules
• Medical device internal connections

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 120-position dual-edge specification. Confirm that the gold flash plating meets application requirements for contact reliability. Ensure the target PCB thickness falls within the supported range of 0.051" to 0.071". Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, small-pitch connection is required for dual-edge cards. The 0.050" pitch allows for dense signal routing compared to larger spacing options. The cantilever contact style offers easier insertion force characteristics compared to straight-wipe contacts. Consider the through-hole termination requirement for PCB layout and manufacturing processes.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 Series, which specializes in standard card edge solutions. The series offers extensive configurability regarding position count, contact type, and housing variations. The 302-120-621-201 represents a high-pin-count variant suitable for complex data or power distribution needs within compact form factors.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 120-position count, 0.050" pitch, and dual-edge female contact configuration. Verify compatibility with the same PCB thickness range and through-hole mounting style. Cross-reference electrical ratings and material specifications to ensure equivalent performance in the target environment.
