305-086-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-086-521-203 is a standard card edge connector receptacle from the 305 series, featuring 86 positions in a dual-row configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing with a 0.140-inch (3.56 mm) row spacing. Designed for panel mount installation at a vertical angle, it accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms insulation voltage, this component supports solder pin termination.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure board alignment
• Features a low-profile insulator body for compact integration
• Provides robust electrical performance with 5A current rating and high dielectric strength

Edgeboard Connectors Applications

• Industrial control systems requiring high-density interconnects
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact type and insulation color. Confirm that the host panel design accommodates the vertical mounting style and the specified board thickness tolerance. Ensure compatibility with the intended polarizing key system if mechanical locking is required for the application environment.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count dual-row interface is necessary for rigid PCBs. The 3.96 mm pitch offers a balance between density and manufacturability. Consider the 1800 VACrms rating for applications requiring significant isolation between rows or circuits within the connector assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial electronics. The series offers various position counts and termination styles, allowing engineers to scale designs while maintaining consistent mechanical and electrical characteristics across different product lines.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include variations such as 305-086-521-201 or 305-086-521-568, which may differ only in insulation color or minor packaging attributes. Verify that any alternative part maintains the identical 86-position count and 0.156-inch pitch to ensure mechanical fit.
