305-072-521-501

Edgeboard Connectors Overview

The EDAC Inc. 305-072-521-501 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 and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts for reliable signal transmission and is designed for PCB mount installation. Constructed with a thermoplastic polyester insulator, it operates within a temperature range of -40°C to +105°C and supports a current rating of 5 A per contact.

Edgeboard Connectors Feature Summary

• Dual-row receptacle design accommodating non-specified dual-edge card types
• Gold-plated copper alloy contacts ensure durable electrical connectivity
• Low-profile insulator body constructed from thermoplastic polyester
• Straight mounting style compatible with standard panel or PCB integration

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact plating thickness, flange options, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the dual-row configuration aligns with the mechanical constraints of the host enclosure. Cross-reference the RoHS status and material declarations with current regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required for standard thickness cards. The 3.96 mm pitch dictates the trace routing density on the mating board. Consider the straight mounting orientation and lack of integrated locking mechanisms if additional mechanical retention is needed. Evaluate the thermal operating range and current capacity against the specific load requirements of the application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors, which are widely used in industrial and commercial applications. The series offers various position counts and row configurations to support diverse modular system designs. The 305 series is characterized by its consistent 3.96 mm pitch and robust construction, providing a standardized solution for connecting peripheral cards to backplanes or motherboards in electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series variants with identical pin counts and row configurations, such as 305-072-520-504, provided the termination style and flange features match the design requirements. Verify that any alternative maintains the same 3.96 mm pitch and 1.57 mm board thickness tolerance to ensure mechanical fit and electrical performance equivalence.
