337-056-544-802

Edgeboard Connectors Overview

The EDAC Inc. 337-056-544-802 is a standard dual-row card edge connector designed for vertical through-hole mounting. It features 56 positions with a 3.96 mm pitch, accommodating PCBs with a thickness of 1.57 mm. The contacts are constructed from copper alloy and gold-plated to ensure reliable signal transmission, rated for 3 A current. The housing utilizes thermoplastic polyester for durability. This component supports wire wrap termination and operates within a temperature range of -40 C to +105 C, offering an insulation resistance of 5 GOhms.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides robust connection stability for double-sided circuit boards.
• Vertical orientation facilitates efficient space utilization in dense electronic assemblies.
• Gold-plated copper alloy contacts ensure low contact resistance and corrosion resistance.
• Thermoplastic polyester housing offers mechanical strength and thermal stability.

Edgeboard Connectors Applications

• Industrial control systems requiring durable board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing reliable signal pathways

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, termination style, and flange configuration. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the wire wrap termination method aligns with the assembly process. Cross-reference the RoHS status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row interface with 56 positions is required for vertical mounting applications. The 3.96 mm pitch and 1.57 mm board thickness compatibility define the mechanical constraints. Consider the 3 A current rating and operating temperature range to ensure electrical performance meets system requirements. Verify that wire wrap termination is suitable for the manufacturing workflow compared to solder lug alternatives.

Edgeboard Connectors Part Context

This component belongs to the EDAC 337 series of standard card edge connectors. The series is characterized by high-density configurations and versatile mounting options. The 337-056-544-802 variant specifically addresses applications needing a 56-position dual-row interface with vertical through-hole installation, distinguishing it from single-row or surface-mount variants within the broader product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include part numbers such as 337-056-544-878, which shares similar positioning but may differ in termination style. Always validate mechanical dimensions and electrical ratings against the original design specifications before implementing any cross-referenced component to ensure functional equivalence.
