305-074-555-258

Edgeboard Connectors Overview

The EDAC Inc. 305-074-555-258 is a standard card edge connector from the 305 series, featuring a dual female configuration with 74 positions. It utilizes a 3.96 mm (0.156 inch) contact spacing and a 3.56 mm row spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Contacts are gold-plated copper alloy, rated for 5 A current, and terminated via solder pins. The insulator body is green thermoplastic polyester, supporting an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration designed for non-specified dual-edge card insertion
• Gold-plated copper alloy contacts ensure reliable electrical performance
• Low-profile insulator body accommodates standard 0.062 inch board thickness
• Panel mount installation style with vertical orientation

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment backplanes
• Test and measurement instrumentation modules
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffixes against official EDAC documentation to ensure correct contact plating, termination type, and mounting features. Confirm that the target application supports the specified 3.96 mm pitch and board thickness requirements. Check RoHS compliance status and environmental ratings relevant to the deployment zone. Ensure panel cutout dimensions align with the connector's flange specifications for proper mechanical fit.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-row interface is required for thick PCBs. The 3.96 mm pitch offers wider spacing compared to finer pitches, potentially simplifying manufacturing. Verify that the 5 A current rating meets the signal or power distribution needs. Consider the vertical panel mount style if space constraints favor this orientation over right-angle board mounts.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 Series, which provides various configurations for card edge applications. The series is characterized by its durable construction and standardized dimensions, facilitating interchangeability within compatible system designs. It serves as a critical interconnect solution in modular hardware architectures where frequent card insertion and removal may occur.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 74-position count, 3.96 mm pitch, and dual female configuration. Verify compatibility with 0.062 inch board thickness and gold plating requirements. Cross-reference mechanical drawings for panel mount hole patterns and overall envelope dimensions to ensure physical fit in existing enclosures.
