305-084-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-084-521-502 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 84 positions with a 0.156-inch (3.96 mm) pitch and accepts PCB thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 5 A current rating and thermoplastic polyester housing. It supports vertical panel mounting via solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffix digits against official EDAC documentation to ensure correct contact plating, housing color, and flange specifications. Confirm that the target application requires a dual-edge connector compatible with the specified 3.96 mm pitch and 84-position count. Check RoHS compliance status if required by project regulations.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge interface is required for vertical panel integration. Ensure the mating card thickness falls within the 1.37 mm to 1.78 mm range. Consider the 5 A current rating and operating temperature limits relative to the system's thermal environment. Verify that the solder pin termination method aligns with the assembly process.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which offers various position counts and configurations for card edge applications. The series is characterized by its use of thermoplastic polyester housings and gold-plated copper alloy contacts. It serves as a standardized solution for connecting double-sided printed circuit boards in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for alternative part numbers with different position counts or contact configurations. Cross-reference with other EDAC series such as 315 or 355 if mechanical dimensions or specific flange requirements differ.
