305-084-500-208

Edgeboard Connectors Overview

The EDAC Inc. 305-084-500-208 is a standard card edge connector receptacle featuring 84 positions arranged in a dual row configuration. It utilizes a 3.96 mm (0.156 inch) contact spacing with a 3.56 mm (0.140 inch) row spacing. The component accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Electrical specifications include a current rating of 5 A and gold-plated copper alloy contacts. The housing is constructed from green thermoplastic material, designed for panel mount installation.

Edgeboard Connectors Feature Summary

• Dual row female connector design accommodating standard thickness PCBs
• Gold-plated copper alloy contacts for reliable signal transmission
• Green thermoplastic insulator body for low profile integration

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm mechanical variations such as mounting style or termination type. Ensure compatibility with the target PCB thickness of 1.57 mm. Confirm that the 84-position dual row layout matches the footprint requirements. Check for RoHS compliance status if required by project specifications. Validate lead time availability through authorized distributors.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for double-sided edge cards. The 3.96 mm pitch offers a balance between pin count and board space. Consider the panel mount orientation for chassis integration. Verify that the 5 A current rating meets the application's power distribution needs. Ensure the gold plating level is sufficient for the expected mating cycles.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts and row configurations for diverse interface needs. The 305-084-500-208 specifically addresses applications requiring 84 connections in a compact dual-row format. It complements other variants in the family that offer different pitches or single-row layouts.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-086-500-201, which offers 86 positions with identical spacing and mounting characteristics. Evaluate the 305-084-500-201 if minor positional adjustments are acceptable. Cross-reference mechanical drawings to ensure housing dimensions and terminal alignment remain compatible with existing tooling.
