305-076-500-203

Edgeboard Connectors Overview

The EDAC 305-076-500-203 is a standard card edge connector featuring 76 positions with a 3.96 mm (0.156 inch) pitch. Designed for dual-edge non-specified cards, it utilizes gold-plated copper alloy contacts and a thermoplastic polyester housing. The component supports a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. It accommodates PCB thicknesses between 1.37 mm and 1.78 mm, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Features gold-plated contacts on a copper alloy base for reliable conductivity
• Provides high dielectric strength with an 1800 VACrms rating

Edgeboard Connectors Applications

• High-density electronic module interconnection

• Telecommunications equipment signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to ensure compatibility with required polarizing key configurations and mounting styles. Confirm that the thermal and electrical ratings align with the target application environment before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a 76-position interface is required for dual-edge cards. Ensure the mating PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Verify that the 5 A current capacity and 1800 VACrms insulation requirements meet the system design specifications.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, all sharing a consistent 3.96 mm pitch architecture designed for robust mechanical and electrical performance in demanding industrial environments.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series variants such as 305-070-556-568 or 305-048-520-501 if different position counts are needed. Ensure any substitute maintains the same 3.96 mm pitch and dual-edge female contact configuration.
