306-023-500-103

Overview

The EDAC Inc. 306-023-500-103 is a dual-row female card edge connector designed for vertical panel and through-hole mounting. It features 46 positions with a 0.156-inch (3.96mm) contact spacing, accommodating printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. The connector utilizes copper alloy contacts with tin plating and a thermoplastic polyester insulator body. Operating within a temperature range of -40°C to 105°C, it complies with RoHS3 standards and is classified under ECCN EAR99.

Feature Summary

• Dual-row configuration providing 46 total connection points
• Vertical panel mount design with through-hole termination
• Copper alloy contacts with tin surface treatment
• Thermoplastic polyester insulator material

Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• General-purpose electronic enclosures needing high-density connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current 306 series guide to ensure compatibility with required board thickness and contact plating specifications. Confirm that the tin-plated variant aligns with environmental compliance requirements such as RoHS3. Cross-reference the part number with official distributor catalogs to validate availability status and lead times prior to finalizing procurement orders.

Selection Notes

Select this component when a dual-row interface is necessary for applications demanding higher pin counts within a single connector footprint. Ensure the mating PCB thickness falls within the specified 0.054 to 0.070 inch range to guarantee proper mechanical engagement. Consider the tin plating option if cost-effectiveness is prioritized over the corrosion resistance offered by gold finishes in harsh environments.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors, which are characterized by their dual-row layout and vertical mounting orientation. The series offers various position counts and plating options to suit different density and environmental needs. The 306-023-500-103 specifically addresses applications requiring 46 connections with a 0.156-inch pitch.

Replacement Considerations

Consult the official EDAC 306 series ordering guide for direct substitutes with differing position counts or plating types. Verify mechanical dimensions and electrical ratings before substituting with components from other manufacturers to ensure panel fit and signal integrity.
