305-078-555-502

Edgeboard Connectors Overview

The EDAC Inc. 305-078-555-502 is a standard card edge connector from the 305 Series, designed for dual-edge board insertion. It features 78 positions arranged in a double row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector supports a maximum PCB thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A current, it employs a solder pin termination method for secure panel mounting. The thermoplastic insulator housing provides electrical insulation, while the vertical installation style facilitates integration into chassis or panel applications requiring robust interconnect solutions.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact contact plating thickness, insulator color, and termination style variations. Ensure compatibility with the target PCB thickness of 1.57 mm and verify that the 3.96 mm pitch aligns with the design layout. Confirm RoHS compliance status through the latest documentation provided by EDAC Inc. before finalizing procurement specifications.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 3.96 mm spacing is required for panel-mount applications. The 78-position count suits designs needing extensive I/O connectivity within a single connector footprint. Consider the 5 A current rating and gold plating for environments prioritizing long-term reliability and low contact resistance over cost-sensitive alternatives.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors engineered for general-purpose electronic applications. The series offers various position counts and termination options to accommodate diverse board layouts. The 305-078-555-502 variant specifically addresses needs for high-pin-count, dual-edge connections with durable metallic contacts and stable plastic housing materials.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 Series variants such as 305-078-555-507 or 305-078-555-208 for potential substitutes with similar pin counts but different termination or housing characteristics. Verify dimensional compatibility and electrical ratings before substituting.
