305-074-555-204

Edgeboard Connectors Overview

The EDAC 305-074-555-204 is a standard card edge connector receptacle featuring 74 positions arranged in two rows. 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 component employs gold-plated copper alloy contacts for reliable signal transmission and offers a continuous current rating of 5 A. Designed for vertical PCB mount installation, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific position count and row configuration against the official EDAC datasheet before procurement. Confirm that the target application requires the specified 1.57 mm board thickness compatibility. Ensure environmental conditions remain within the documented operating temperature range to maintain performance integrity.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. Consider the 5 A current rating and 1800 VACrms voltage capability for appropriate load handling. Verify compatibility with existing polarizing key requirements and panel mounting constraints during the design phase.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series provides various position counts while maintaining consistent 3.96 mm spacing and 5 A ratings. These connectors are designed for durable, high-reliability connections in demanding electronic environments.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the EDAC 305 series for alternative position counts. Verify mechanical dimensions and electrical ratings match the original design requirements before substitution.
