306-022-500-103

Overview

The EDAC Inc. 306-022-500-103 is a dual-row card edge connector designed for panel mounting with through-hole termination. It features 44 positions (9 pins per row across 2 rows) with a 0.156-inch (3.96mm) contact spacing. The connector utilizes copper alloy cantilever contacts with 10.0µin gold plating, housed in green thermoplastic polyester. It accepts double-sided cards with thicknesses between 0.054 and 0.070 inches. Operating temperatures range from -40°C to 105°C.

Feature Summary

• Dual female contact configuration for reliable signal transmission
• Cantilever spring contact design ensures secure board retention
• Gold-plated terminals provide corrosion resistance and low contact impedance
• Panel mount flange with top opening facilitates easy installation

Applications

• Industrial control system interconnects
• Computing and storage hardware backplanes
• Aerospace avionics modules
• Medical device circuit boards

Procurement Notes

Verify the specific ordering suffix against the official EDAC 306 Series Ordering Guide to ensure correct pin count, contact spacing, and termination style match the design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors, as standard delivery periods may vary by region and supply chain conditions.

Selection Notes

Select this component when a dual-sided card edge interface with 0.156-inch spacing is required. Ensure the target PCB thickness falls within the 0.054 to 0.070-inch range for proper mechanical engagement. Consider the 306 series family for compatible mating connectors and verify thermal ratings against operational environment constraints.

Part Context

This part belongs to the EDAC 306 Series, a line of card edge connectors established for robust rack and panel applications. The series offers various configurations for computing, industrial, and communications sectors. The 306 model specifically targets high-reliability environments requiring durable mechanical connections and stable electrical performance over extended temperature ranges.

Replacement Considerations

Consult the EDAC 306 Series cross-reference guide for direct substitutes. Verify that alternative parts maintain identical 0.156-inch spacing, 44-position count, and dual-row geometry to ensure mechanical compatibility without redesign.
