346-048-559-108

Edgeboard Connectors Overview

The EDAC Inc. 346-048-559-108 is a standard card edge connector receptacle featuring 48 positions with a 3.175 mm (0.125 inch) pitch. Designed for single-edge board insertion, it utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. The component supports a 3 A current rating and accommodates a board thickness of 1.57 mm. It employs a through-hole mounting style with wire wrap termination for secure PCB attachment. The housing is constructed from thermoplastic polyester, providing structural integrity and insulation.

Edgeboard Connectors Feature Summary

• Gold-plated contacts provide corrosion resistance and stable electrical connectivity
• Thermoplastic polyester housing ensures durable insulation properties
• Wire wrap termination facilitates secure through-hole PCB integration

Edgeboard Connectors Applications

• Single-sided printed circuit board interconnections
• Industrial control system module interfaces
• Telecommunications equipment backplane connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact termination type and orientation. Ensure compatibility with the target board thickness of 1.57 mm before procurement. Cross-reference the 48-position count and 3.175 mm pitch requirements with design specifications. Confirm that the wire wrap termination method aligns with available assembly tools and processes.

Edgeboard Connectors Selection Notes

Select this component when a single-row, 48-position interface is required for standard thickness boards. Consider the 3.175 mm pitch constraint for trace routing density. Evaluate the wire wrap termination against available manufacturing capabilities compared to solder pin alternatives. Verify that the thermoplastic polyester material meets environmental operating temperature requirements for the intended application.

Edgeboard Connectors Part Context

This part belongs to the EDAC 346 series of standard card edge connectors. The series offers various position counts and termination options within the same mechanical footprint. The 346 series is designed for general-purpose electronic applications requiring robust single-edge board connections. Other variants in the series may differ in contact plating, housing material, or mounting angle.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 346 series parts with matching 48 positions and 3.175 mm pitch, such as 346-044-559-201 or 346-030-541-201, provided the position count matches. Verify that alternative parts maintain the same wire wrap termination and through-hole mounting style to ensure mechanical compatibility.
