305-078-500-278

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-278 is a standard card edge connector from the 305 Series, designed for dual-row applications with a 78-position configuration. It features a 3.96 mm (0.156 inch) pitch and supports a maximum operating temperature of +105°C and a minimum of -40°C. The connector utilizes copper alloy contacts with gold plating and employs a solder eyelet termination method. Constructed with a thermoplastic insulator, it is intended for panel mount installation in vertical orientations.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 78 contact positions
• Gold-plated copper alloy contacts for reliable signal transmission
• Solder eyelet termination style for secure board attachment

Edgeboard Connectors Applications

• Panel-mounted electronic assemblies requiring high-density connections
• Industrial control systems utilizing card edge interface standards
• Test and measurement equipment needing robust vertical mounting solutions

Edgeboard Connectors Procurement Notes

Verify the specific termination style against design requirements, as datasheets may list variations such as solder eyelets or pins for similar part numbers. Confirm that the panel thickness accommodates the specified 1.57 mm board thickness constraint. Ensure compatibility with the 3.96 mm pitch to prevent mechanical misalignment during assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 78-position connector is required for vertical panel mounting. The 3.96 mm pitch distinguishes it from finer-pitch alternatives. Verify that the operating temperature range of -40°C to +105°C meets environmental conditions. Consider the solder eyelet termination if through-hole mounting with specific lead configurations is preferred over standard pins.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 Series, which offers various position counts and termination options within the same pitch family. Similar parts like 305-078-500-508 share the same physical dimensions and electrical characteristics but may differ in termination type or packaging. The series provides standardized interfaces for modular electronic designs.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series variants with identical 78-position and 3.96 mm pitch specifications, such as 305-078-500-508, provided the termination style matches the application needs. Cross-manufacturer replacements must strictly adhere to the 3.96 mm pitch and dual-row geometry.
