305-068-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-068-521-203 is a dual-row card edge connector designed for panel mount and through-hole termination. It features 68 positions with a 0.156-inch (3.96 mm) spacing. The connector accepts non-specified double-sided cards with thicknesses ranging from 0.054 to 0.070 inches. Contacts are made of copper alloy with gold plating, rated for 5 A continuous current and 1800 VACrms insulation voltage. The housing is green thermoplastic polyester, operating between -40°C and +105°C.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC 305 Series Ordering Guide to ensure correct contact configuration and flange style. Confirm that the target PCB or card meets the specified thickness range of 0.054 to 0.070 inches for proper mechanical engagement. Check RoHS compliance status if required by project specifications.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count, double-sided interface is required with a 3.96 mm pitch. Ensure the application environment falls within the -40°C to +105°C operating temperature range. Verify that the mating card supports the necessary polarizing key configurations compatible with the 305 series design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for durability and versatility. The series offers various pin counts and flange options to accommodate different panel thicknesses and mounting requirements. It is widely used in applications demanding stable interconnects for double-sided edgeboards.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series cross-reference guide for direct substitutes. Compatible alternatives may include other EDAC series with matching pitch and pin count, provided flange dimensions and termination styles align with the existing assembly constraints.
