305-082-555-503

Edgeboard Connectors Overview

The EDAC Inc. 305-082-555-503 is a standard card edge connector header featuring 82 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy with gold plating to ensure reliable signal transmission. Designed for panel mounting at a vertical angle, this component provides secure interconnection for high-density applications requiring robust mechanical stability.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design accommodates non-specified dual-sided card edge PCBs
• Gold-plated copper alloy contacts provide corrosion resistance and low contact resistance
• Vertical panel mount style ensures stable alignment with mating connectors
• Thermoplastic insulator body offers structural integrity within specified temperature ranges

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Automotive electronic control unit interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, row configuration, and termination type. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the vertical panel mount orientation aligns with the mechanical enclosure design requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this model when a high-pin-count dual-row interface is required for vertical panel mounting. The 3.96 mm pitch supports standard board layouts while the gold plating ensures durability in demanding environments. Consider the thermoplastic housing material for thermal stability up to 105°C during operation and verify space constraints for the panel-mounted footprint.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 Series, which specializes in standard card edge connectors. The series offers various position counts and mounting options, maintaining consistent 3.96 mm spacing across models. The 305-082 variant represents a high-density solution within this family, designed for applications requiring extensive I/O connections in a compact vertical profile.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series headers with identical 82-position dual-row configurations and matching 3.96 mm pitch. Verify that alternative part numbers maintain the same vertical panel mount style and gold-plated contact specifications to ensure functional interchangeability without mechanical redesign.
