305-072-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-072-556-208 is a standard card edge connector receptacle featuring 72 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) pitch and accommodates a board thickness of 1.37 mm (0.054 inch). The contacts are gold-plated copper alloy, rated for 5 A current. Designed for panel mounting with vertical orientation, it employs solder lug termination. The housing is constructed from green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female contact configuration for high-density signal routing
• Gold-plated copper alloy contacts ensure reliable conductivity and corrosion resistance
• Thermoplastic polyester housing provides thermal stability within specified operating ranges
• Panel mount design with vertical orientation facilitates secure structural integration

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standard board thicknesses
• Automotive electronics modules needing high-current capacity connections
• Test and measurement instrumentation boards

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact plating thickness, flange style, and termination type variations. Ensure compatibility with the target PCB edge thickness of 1.37 mm before procurement. Cross-reference the RoHS compliance status with the latest regulatory documentation provided by EDAC Inc. to meet environmental standards for your region.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 72-position interface is required for panels rather than PCBs. Confirm that the 3.96 mm pitch aligns with the mating card edge layout. Verify that the vertical panel mount style suits the enclosure design constraints. Ensure the 5 A current rating per contact meets the electrical load requirements of the application circuitry without exceeding thermal limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting styles. The 305-072-556-208 specifically denotes a 72-position dual-row receptacle. It is distinct from header variants and single-row configurations within the same product family line.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series parts with identical 72-position dual-row specifications and matching 3.96 mm pitch. Verify mechanical dimensions and flange mounting hole patterns to ensure physical interchangeability. Contact manufacturers for cross-reference lists if alternative brands are considered.
