337-082-521-807

Edgeboard Connectors Overview

The EDAC Inc. 337-082-521-807 is a standard card edge connector socket from the 337 series, designed for through-hole mounting. It features 82 positions with a 0.156-inch (3.96 mm) pitch and supports dual-edge card types. The connector utilizes copper alloy contacts with gold plating and a thermoplastic polyester housing. Rated for 3 A current, it accommodates board thicknesses between 1.37 mm and 1.78 mm. Operating temperatures range from -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female connector design for secure mating with specified card edge boards
• Through-hole termination with wire wrap or PC pin options for reliable circuit integration
• Gold-plated copper alloy contacts ensure low resistance and corrosion resistance
• Thermoplastic polyester housing provides structural stability and thermal endurance

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing hardware interfaces

Edgeboard Connectors Procurement Notes

Verify the specific termination style required for your PCB layout, as the 337 series offers both wire wrap and PC pin variants. Confirm that the target card edge thickness falls within the 1.37 mm to 1.78 mm operational range. Ensure compatibility with the 0.156-inch pitch and 82-position configuration before finalizing component selection for production.

Edgeboard Connectors Selection Notes

Select this model when a high-density, dual-sided card interface is required for robust signal transmission. The 3 A rating suits moderate power applications, while the gold plating ensures longevity in demanding environments. Consider the vertical or right-angle mounting orientation based on chassis constraints and ensure the thermoplastic polyester housing meets thermal requirements.

Edgeboard Connectors Part Context

This component belongs to the EDAC 337 series of standard card edge connectors, which are widely used in modular electronic systems. The series offers various position counts and termination styles to accommodate diverse board designs. The 337-082 variant specifically addresses high-pin-count applications requiring reliable dual-edge connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 337-082-520-807 and 337-082-541-858, which share identical electrical and mechanical specifications but may differ in termination type or packaging. Verify that any replacement maintains the 82-position count and 3.96 mm pitch to ensure board compatibility.
