305-072-555-258

Edgeboard Connectors Overview

The EDAC 305-072-555-258 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 pitch and a 3.56 mm row spacing. Designed for PCB mounting with straight orientation, it accepts boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are copper alloy with gold plating, rated for 5 A continuous current. The housing is made of green thermoplastic polyester, supporting an operating temperature range from -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female connector design for non-specified dual-edge cards
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body constructed from thermoplastic polyester
• Accepts between-contact and in-contact polarizing keys

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Automotive electronics modules needing high-current capacity connectors

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact pin count, row configuration, and termination style. Ensure compatibility with the target printed circuit board thickness and polarizing key requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 72-position dual-row interface is required with a 3.96 mm pitch. Confirm that the application environment stays within the specified -40°C to +105°C temperature range and that the 5 A current rating per contact meets the electrical load requirements of the system design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and mounting options, characterized by a consistent 3.96 mm pitch and durable thermoplastic polyester housings suitable for general-purpose electronic interconnect applications.

Edgeboard Connectors Replacement Considerations

Consult the EDAC 305 Series Ordering Guide for direct substitutes. Verify identical specifications including 72 positions, dual-row layout, 3.96 mm pitch, and gold plating before substituting.
