306-018-520-103

Edgeboard Connectors Overview

The EDAC Inc. 306-018-520-103 is a standard card edge connector from the 306 Series, designed for vertical panel mounting applications. It features a dual female configuration with 36 positions and a contact spacing of 0.156 inches (3.96 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it ensures reliable electrical performance within an operating temperature range of -40°C to 105°C. The insulator body is made of green thermoplastic material.

Edgeboard Connectors Feature Summary

• Dual edge female contact configuration for secure board insertion
• Low profile insulator body design for compact integration
• Gold-plated copper alloy contacts for corrosion resistance
• Flush mount flange with floating bobbin feature

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge connections
• Communication equipment interface modules
• Medical device internal circuit board assemblies
• Consumer electronics mainboard interconnects

Edgeboard Connectors Procurement Notes

Verify the specific position count and series designation against official EDAC documentation before procurement, as distributor listings may contain conflicting data regarding pin counts or suffix variations. Confirm that the required PCB thickness matches the 1.57 mm specification to ensure proper mechanical engagement. Check regional availability and shipping restrictions, as some distributors indicate limited stock or non-availability in certain areas. Ensure compliance with RoHS requirements if applicable to your assembly standards.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided card edge interfaces. The 3.96 mm pitch suits applications needing wider spacing between signal lines compared to finer pitches. Consider the flush mount flange with floating bobbin for alignment tolerance in panel installations. Verify that the 105°C maximum operating temperature meets the thermal environment of the target application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series of card edge connectors, which are characterized by their low-profile insulator bodies and single centerline row configurations. The series is designed for general-purpose electronic interconnections where reliable signal transmission is critical. The 306 Series offers various position counts and mounting styles to accommodate different board sizes and panel requirements.

Edgeboard Connectors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. When evaluating alternatives, ensure that any replacement matches the 3.96 mm pitch, 36-position count, dual female contact type, and vertical panel mount style. Verify compatibility with 1.57 mm PCB thickness and similar thermal ratings.
