305-086-520-203

Edgeboard Connectors Overview

The EDAC Inc. 305-086-520-203 is a standard card edge connector receptacle featuring 86 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The component employs gold-plated copper alloy contacts to ensure reliable signal transmission, supporting a continuous current rating of 5 A. Designed for panel mounting with a vertical orientation, the unit uses solder pin termination for secure PCB attachment. The insulator body is constructed from thermoplastic material, providing structural integrity within an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for precise alignment
• Low profile insulator body design for compact integration
• Dual row configuration supporting high-density interconnect applications

Edgeboard Connectors Applications

• Industrial control systems requiring robust card edge interfaces
• Telecommunications equipment utilizing standardized board thicknesses
• Computing hardware modules needing high-pin-count vertical connections

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required polarization key compatibility and termination style. Confirm that the thermal rating aligns with the operational environment limits. Ensure the panel mount orientation fits the mechanical enclosure constraints. Cross-reference the contact plating specifications against corrosion requirements. Validate the board thickness tolerance against the manufacturing specifications of the mating PCB.

Edgeboard Connectors Selection Notes

Select this component when a high-pin-count vertical interface is required for thick PCBs. The dual-row layout maximizes connection density within a limited footprint. Verify that the 5A current rating meets the power distribution needs of the application. Consider the polarizing key options if misalignment prevention is critical. Ensure the solder pin termination method is compatible with the assembly process.

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 while maintaining consistent electrical characteristics. The 305 series is designed for reliability in demanding environments, featuring durable materials and precise dimensional tolerances. This specific model represents a high-position variant within the family, suitable for complex system architectures.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series parts with matching 86-position counts and 3.96mm pitch. Verify that alternative models support the same 1.57mm board thickness and vertical panel mount style. Check for identical current ratings and polarizing key acceptance capabilities before substitution.
