305-048-521-503

Edgeboard Connectors Overview

The EDAC Inc. 305-048-521-503 is a standard card edge connector from the 305 Series, designed for dual female board-to-board connections. It features 48 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector utilizes gold-plated copper alloy terminals with a half-bermuda contact type and solder pin termination. It accommodates PCB thicknesses between 1.37 mm and 1.78 mm and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Feature Summary

• Dual female configuration for reliable board-to-board interconnection
• Gold-plated copper alloy contacts ensure stable signal transmission
• Thermoplastic polyester insulation provides structural integrity
• Solder pin termination facilitates secure panel or board mounting

Edgeboard Connectors Applications

Edgeboard Connectors Procurement Notes

Verify that the specific suffix 521-503 matches the required flange and mounting style, as variations exist within the 305 series. Confirm RoHS compliance status and lead times directly with authorized distributors, as availability may vary by region. Ensure the target PCB thickness falls within the specified 1.37 mm to 1.78 mm range before finalizing procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, 48-position interface with a 3.96 mm pitch is required. The gold plating and copper alloy construction suit applications prioritizing conductivity and durability over cost-sensitive alternatives. Consider the vertical mounting orientation and specific flange dimensions to ensure mechanical compatibility with the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors known for their versatility in industrial and commercial applications. The series offers various position counts and mounting styles, allowing engineers to scale designs while maintaining consistent electrical characteristics and form factors across different product generations.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants with matching 48-position counts and 3.96 mm pitch, such as 305-048-520-512 or 305-048-500-201, provided the flange and mounting specifications align with the original design requirements.
