302-120-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-120-221-201 is a standard card edge connector from the 302 Series, designed for dual-edge board applications. It features 120 positions arranged in two rows with a 0.050" (1.27mm) contact spacing. The connector utilizes female copper alloy contacts with gold flash plating and a black polyamide (PA66) housing. It supports PCB thicknesses between 0.051" and 0.071" (1.30mm to 1.80mm). Rated for operation from -55°C to 85°C, it employs a cantilever contact type and mounts via board edge or straddle mount methods.

Edgeboard Connectors Feature Summary

• Dual-edge configuration accommodates non-specified card types with two rows of contacts
• Cantilever contact design ensures reliable electrical connection across varying board thicknesses
• Gold flash plated copper alloy terminals provide corrosion resistance and stable conductivity
• Polyamide (PA66) insulation housing offers structural stability within specified thermal limits

Edgeboard Connectors Applications

• High-density electronic module interconnections
• Industrial control system backplanes
• Telecommunications equipment signal routing
• Automotive electronics interface boards

Edgeboard Connectors Procurement Notes

Verify the specific part number suffix against manufacturer documentation to confirm exact pin count and plating specifications. Ensure compatibility with target PCB thickness ranges before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference lead times with authorized distributors as availability may fluctuate based on production schedules.

Edgeboard Connectors Selection Notes

Select this component when high pin density is required within a compact footprint using 1.27mm spacing. Suitable for designs requiring robust mechanical retention through straddle mounting. Consider thermal operating range constraints for harsh environments. Validate that the target card edge thickness falls within the supported 1.30mm to 1.80mm window for optimal contact engagement.

Edgeboard Connectors Part Context

Part of the EDAC 302 Series standard card edge connectors, focusing on dual-edge applications. Designed for general-purpose interconnect needs where reliability and density are prioritized. Commonly used in modular systems requiring frequent insertion and removal cycles.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 series variants with matching pin counts and spacing. Verify equivalent mechanical dimensions and contact material specifications when considering alternative manufacturers.
