306-024-521-103

Overview

The EDAC Inc. 306-024-521-103 is a dual-edge female card edge connector designed for panel mount applications. It features 56 positions arranged in two rows of 24 contacts with a single centerline row configuration. The connector utilizes a 0.156-inch (3.96mm) contact spacing and accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches. Contacts are made of copper alloy with gold plating, ensuring reliable electrical performance within an operating temperature range of -40°C to 105°C.

Feature Summary

• Dual-edge female design accommodates non-specified dual-edge cards
• Gold-plated copper alloy contacts provide corrosion resistance
• Low-profile insulator body constructed from thermoplastic polyester
• Panel mount installation with flanged mounting features

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard edge card interfaces
• Test and measurement instrumentation needing reliable signal transmission

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm contact plating and insulation material specifications. Ensure that the target printed circuit board thickness falls within the accepted range of 0.054 to 0.070 inches prior to integration. Confirm RoHS compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with the latest EDAC series guide to validate availability and lead times through authorized distributors.

Selection Notes

Select this component when a dual-edge female interface is required for panel-mounted configurations. The 0.156-inch pitch suits applications where standard spacing is necessary without high-density constraints. Consider the gold contact finish for environments demanding long-term reliability and low contact resistance. Evaluate the mechanical stability provided by the flanged mounting style against vibration requirements in the target deployment scenario.

Part Context

This connector belongs to the EDAC 306 Series, which offers a range of card edge solutions for various industrial and commercial applications. The series provides options for different pin counts and mounting styles, allowing engineers to scale designs while maintaining consistent mechanical and electrical characteristics across the product line.

Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing but differing flange or plating options. Verify compatibility with existing PCB layouts before swapping components to ensure mechanical fit and electrical continuity remain unaffected.
