305-072-521-558

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-558 is a standard card edge connector receptacle featuring 72 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm row spacing. Designed for .062 inch (1.57 mm) nominal thickness printed circuit boards, the unit employs gold-plated copper alloy contacts and a thermoplastic polyester insulator body. The component supports a maximum operating temperature of +105°C and a minimum of -40°C.

Edgeboard Connectors Feature Summary

• Dual-row receptacle design accommodating 72 signal paths
• Gold-plated copper alloy contacts for reliable conductivity
• Low-profile insulator body constructed from thermoplastic polyester
• Compatible with standard .062 inch nominal thickness PCBs

Edgeboard Connectors Applications

• Industrial control systems requiring robust panel-mounted interfaces
• Telecommunications equipment utilizing standard card edge modules
• Automotive electronics assemblies demanding high-temperature stability
• Test and measurement instrumentation hardware

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against official EDAC documentation to confirm exact plating thickness and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Confirm RoHS compliance status through current manufacturer declarations. Cross-reference the 72-position count with mechanical constraints. Validate thermal ratings against operational environment requirements.

Edgeboard Connectors Selection Notes

Select this component when a dual-row interface with 72 positions is required for .062 inch thick boards. The 3.96 mm pitch suits applications needing wider spacing than micro-connectors. Gold plating ensures durability in repeated mating cycles. Verify that the thermoplastic polyester housing meets chemical resistance needs. Confirm panel mounting requirements align with the physical dimensions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and row configurations. The 305 series is characterized by its low-profile design and compatibility with standard PCB thicknesses. This specific model represents a high-density option within the lineup.

Edgeboard Connectors Replacement Considerations

Direct substitutes include EDAC 305-072-521-504 and 305-072-521-568. Verify identical pin counts and spacing before substitution. Check datasheets for any differences in termination style or flange features.
