305-058-556-503

Edgeboard Connectors Overview

The EDAC 305-058-556-503 is a standard card edge connector featuring 58 positions 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 1.57 mm nominal thickness printed circuit boards, this header employs gold-plated copper alloy contacts with solder pin termination. The unit incorporates a floating bobbin design to accommodate wave or reflow soldering processes.

Edgeboard Connectors Feature Summary

• Floating bobbin mechanism allows for alignment during wave or reflow soldering
• Dual-edge card extender functionality for board-to-board connectivity
• Straddle mount installation style for secure panel attachment

Edgeboard Connectors Applications

• Board edge interconnects requiring straddle mounting
• Card extender applications for signal routing
• High-density PCB connections using 1.57mm thickness boards

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm contact plating thickness and insulator color specifications. Ensure the target application supports the 3.96mm pitch and 1.57mm board thickness constraints. Confirm that the floating bobbin termination method aligns with the chosen assembly process, whether wave or reflow soldering, to guarantee reliable electrical performance.

Edgeboard Connectors Selection Notes

Select this component when a dual-row connection is required for thick PCBs up to 1.57mm. The 3.96mm pitch offers lower density compared to 2.54mm options but provides robust mechanical stability. Consider the floating bobbin feature if precise alignment during automated soldering is critical. Verify that the vertical orientation and straddle mount style fit the enclosure design requirements.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by thermoplastic insulators and copper alloy contacts. Similar models within the family vary primarily by position count and pitch dimensions, such as the 305-018-555-508 or 305-048-556-508, while maintaining consistent mounting and termination characteristics.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 58-position count, 3.96mm pitch, and dual-row configuration. Verify compatibility with 1.57mm PCB thickness and straddle mount requirements. No alternative part numbers are confirmed in public documentation.
