305-058-500-503

Edgeboard Connectors Overview

The EDAC Inc. 305-058-500-503 is a standard card edge connector header featuring 58 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 nominal 1.57 mm thick printed circuit boards, the unit employs gold-plated copper alloy contacts and a thermoplastic insulator body. The connector supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates double-sided card edge PCBs
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body facilitates compact panel or vertical mounting

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Computing hardware board-to-board connections

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin count, plating thickness, and termination style. Ensure compatibility with the target PCB thickness of 1.57 mm before procurement. Confirm RoHS compliance status and lead time requirements directly with authorized distributors, as availability may vary by region.

Edgeboard Connectors Selection Notes

Select this component when a 58-position dual-row interface is required for 1.57 mm thick cards. The 3.96 mm pitch dictates compatible slot dimensions on the mating card. Verify that the application environment stays within the specified -40°C to +105°C operating range and that the 5 A current rating meets the circuit load requirements.

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 styles, including panel mount headers and PCB mount receptacles. The 305-058-500-503 specifically represents a high-density header option designed for robust mechanical retention and electrical performance in industrial applications.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series headers with identical 58-position dual-row configurations and 3.96 mm pitch. Cross-reference mechanical drawings to ensure matching flange features and mounting hole patterns. Verify that alternative parts support the same 1.57 mm PCB thickness and thermal ratings.
