305-074-556-504

Edgeboard Connectors Overview

The EDAC Inc. model 305-074-556-504 is a standard card edge connector from the 305 series, designed for panel mounting in a vertical orientation. It features 74 positions with a dual female contact configuration and a pitch of 3.96 mm (0.156 inches). The contacts are gold-plated copper alloy, rated for 5 A current, and utilize solder pin termination. The housing is green thermoplastic polyester, supporting PCB thicknesses between 1.37 mm and 1.78 mm, with an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual row female contact interface for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure reliable electrical performance
• Thermoplastic polyester insulator provides structural stability
• Solder pin termination facilitates secure panel mounting

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation panels
• Automotive electronic modules needing high-reliability interconnects

Edgeboard Connectors Procurement Notes

Verify the specific position count and termination style against the official EDAC datasheet before procurement. Confirm that the required PCB thickness falls within the specified 1.37 mm to 1.78 mm range. Ensure compatibility with the target mating card edge specifications. Check for any regional distribution restrictions or RoHS compliance requirements relevant to your project.

Edgeboard Connectors Selection Notes

Select this component when a 74-position dual-row connector is required for vertical panel installation. The 3.96 mm pitch dictates the trace spacing on the mating PCB. Consider the 5 A current rating for power distribution needs. Verify that the green thermoplastic housing meets environmental and thermal requirements for the intended application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which offers various position counts and mounting options. The series is characterized by its use of gold-plated contacts and thermoplastic insulation, providing a balance of durability and electrical reliability for industrial applications.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include models with identical pitch and mounting style but different position counts, such as 305-072-556-504 or 305-076-556-504. Cross-series replacements require matching pitch, current rating, and mechanical dimensions.
