305-086-520-278

Edgeboard Connectors Overview

The EDAC Inc. 305-086-520-278 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 86 positions with a 3.96 mm (0.156 inch) pitch and supports PCB thicknesses of 1.57 mm. The connector utilizes gold-plated copper alloy contacts rated for 5 A current and employs a solder termination method. Housed in a green thermoplastic polyester body, it offers straight PCB mounting and operates within a temperature range of -40°C to 105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Green thermoplastic polyester housing provides insulation
• Solder termination supports standard PCB assembly processes

Edgeboard Connectors Applications

• Industrial control systems requiring high-density connections
• Telecommunications equipment interface modules
• Medical device internal circuit board interconnects

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, pitch, and termination style. Ensure compatibility with target PCB thickness specifications before procurement. Confirm RoHS compliance status through manufacturer datasheets. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Validate environmental operating ranges against application requirements.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count dual-edge connector is required for vertical or panel-mounted assemblies. Consider the 3.96 mm pitch for spacing constraints and the 5 A current rating for power distribution needs. Evaluate the green housing material for visual identification purposes. Assess the solder termination type against available PCB fabrication capabilities. Compare against alternative series if different mounting angles are necessary.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which offer various position counts and mounting configurations. The series is known for robust construction suitable for demanding environments. Similar parts in the series include variants with different pin counts such as 305-086-500-201, maintaining consistent pitch and contact materials while differing in physical dimensions or mounting styles.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include 305-086-500-201 and 305-086-520-278, provided they match the required pin count and termination type. Verify mechanical fit and electrical ratings before substitution. Alternative manufacturers may offer comparable connectors but require full validation of interface compatibility.
