305-078-555-208

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-208 is a standard card edge connector from the 305 Series, designed for dual-edge female connections. It features 78 positions with a contact spacing of 3.96 mm (0.156 inches) and a row spacing of 3.56 mm (0.140 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). Constructed with copper alloy contacts featuring gold plating, it supports a current rating of 5 A and operates within a temperature range of -40°C to +105°C. The unit utilizes a thermoplastic insulator body and employs solder lug termination for secure panel mounting.

Edgeboard Connectors Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Ensure storage conditions maintain integrity of gold-plated contacts against oxidation. Review datasheet specifications for mechanical tolerances to guarantee compatibility with target assembly processes. Validate that ordering suffixes match exact physical dimensions and termination styles required by the design.

Edgeboard Connectors Selection Notes

Select this connector when a high-density dual-edge interface with 3.96 mm pitch is required. Consider the 78-position count for applications needing extensive signal routing in a single slot. Evaluate the 5 A current rating against load requirements. Verify that the 1.57 mm board thickness matches the target PCB design. Assess panel mounting constraints to ensure sufficient clearance for the vertical profile and solder lug termination method.

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 termination options tailored for robust industrial and commercial applications. The 305-078-555-208 variant specifically addresses needs for dual-edge connectivity with extended tail lengths for flexible wiring configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 Series models with matching 78 positions and 3.96 mm spacing, such as 305-078-555-502. Cross-brand replacements require strict verification of pinout, mechanical footprint, and electrical ratings to ensure functional equivalence without redesigning the host assembly.
