333-056-540-803

Edgeboard Connectors Overview

The EDAC Inc. 333-056-540-803 is a standard card edge connector featuring 56 positions arranged in two rows with a 3.96 mm pitch. Designed for vertical through-hole mounting, it utilizes wire wrap termination and gold-plated copper alloy contacts rated for 3 A current. The housing is constructed from thermoplastic polyester, supporting PCB thicknesses of 1.57 mm. It operates within a temperature range of -40°C to +105°C and maintains an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 56 contact positions for high-density interconnect applications
• Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
• Vertical through-hole installation with wire wrap termination for secure board attachment

Edgeboard Connectors Applications

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to confirm exact termination style and plating specifications. Ensure compatibility with the target printed circuit board thickness of 1.57 mm before integration. Confirm that the wire wrap termination method aligns with the assembly process capabilities. Check for any regional distribution restrictions or supply limitations associated with this part number prior to finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with a 3.96 mm pitch is required for vertical mounting. The wire wrap termination necessitates compatible assembly tools and processes. Verify that the 3 A current rating and 5 GOhm insulation resistance meet the electrical requirements of the application. Consider the thermoplastic polyester housing material for environmental durability within the specified operating temperature range.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 333 series, which offers various row counts and termination options. The series is characterized by its standardized 3.96 mm pitch and versatile mounting configurations. Components in this family are designed for general-purpose electronic interconnections across multiple industries.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 56-position count, dual-row layout, 3.96 mm pitch, and vertical wire wrap termination. Verify mechanical dimensions and electrical ratings to ensure functional equivalence without redesigning the host circuit board.
