305-050-520-503

Edgeboard Connectors Overview

The EDAC Inc. 305-050-520-503 is a standard card edge connector from the 305 series, designed for dual female termination with 50 positions. It features a 0.156-inch (3.96 mm) contact spacing and accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The connector utilizes gold-plated copper alloy contacts and a green thermoplastic insulator body. Rated for 5 A current at +105°C maximum operating temperature, it supports vertical panel mounting via solder lug termination.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to confirm exact plating thickness, flange style, and insulation color variations. Ensure the target PCB thickness aligns with the specified 0.062-inch nominal requirement for proper mechanical retention. Confirm RoHS compliance status through the latest datasheet revision before final procurement approval.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 50-position interface is required with a 3.96 mm pitch. It is suitable for applications demanding vertical panel mounting and solder lug termination. Consider the 5 A current rating and 105°C thermal limit during system design. Verify that the mating card edge thickness falls within the acceptable range for secure contact engagement.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles for diverse electronic assembly needs. These connectors are engineered for durability in demanding environments, supporting both single and dual-row configurations with consistent electrical performance across the product line.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes with differing position counts or termination types. Cross-reference compatible parts from other manufacturers only if pinout, spacing, and mechanical dimensions match exactly. Verify that alternative components meet the same thermal and current ratings.
