305-076-555-504

Edgeboard Connectors Overview

The EDAC Inc. 305-076-555-504 is a standard card edge connector from the 305 Series, designed for dual-edge board applications. It features 76 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts featuring gold plating and a green thermoplastic polyester insulator, it supports a current rating of 5 A. The unit utilizes a solder pin termination style and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct contact plating thickness and material specifications. Confirm that the target application accommodates the 0.156-inch pitch and 0.062-inch board thickness requirements. Check RoHS compliance status directly with the supplier documentation prior to final procurement decisions.

Edgeboard Connectors Selection Notes

Select this component when a high-density connection is required for dual-edge circuit boards. The 3.96 mm pitch allows for substantial trace spacing compared to finer pitches. Ensure the mechanical design supports panel mounting and that the operating environment remains within the specified thermal limits for the thermoplastic polyester housing.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series of standard card edge connectors. The series offers various position counts and configurations tailored for different board densities. The 305-076 variant specifically addresses applications needing 76 connection points while maintaining the structural integrity and electrical performance standards defined by the manufacturer for this product line.

Edgeboard Connectors Replacement Considerations

Cross-reference compatible parts within the same EDAC 305 Series family. Verify identical pitch, row count, and board thickness compatibility before substituting.
