305-078-500-504

Edgeboard Connectors Overview

The EDAC Inc. 305-078-500-504 is a standard card edge connector from the 305 series, designed for panel mount vertical installation. It features 78 positions with a 3.96 mm (0.156 inch) contact spacing and dual rows. The connector utilizes gold-plated copper alloy contacts with solder lug termination. It accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The insulator body is green thermoplastic polyester, rated for operation between -40°C and 105°C, and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Vertical panel mount design with flanged housing for secure board retention
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Dual-row configuration accommodates high-density interconnect requirements
• Compatible with standard 0.062 inch thick PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact type and plating specifications. Ensure the target PCB thickness falls within the accepted range of 1.37mm to 1.78mm. Confirm that the application environment temperature remains within the specified -40°C to 105°C operational limits. Check for any specific regulatory compliance requirements such as REACH or RoHS3 depending on the destination market.

Edgeboard Connectors Selection Notes

Select this component when a vertical, panel-mount solution is required for double-sided edge cards. The 3.96 mm pitch suits applications needing wider spacing than standard 2.54 mm connectors. Consider the 78-position count for moderate-to-high pin count needs. Verify that the solder lug termination method aligns with the assembly process capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series, which offers various position counts and mounting styles. The series is characterized by its low-profile insulator body and durable construction. Similar parts in the series include 305-030-500-504 and 305-050-500-504, differing primarily in the number of positions while maintaining consistent electrical and mechanical characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with matching 78 positions and 3.96 mm pitch. Cross-brand replacements require verification of identical PCB thickness tolerance, row spacing, and mounting hole patterns to ensure mechanical compatibility.
