305-048-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-048-556-208 is a standard card edge connector designed for panel mount applications with a vertical orientation. It features 48 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) contact spacing. The connector accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). Constructed with copper alloy contacts featuring gold plating and a green thermoplastic insulator, it supports a current rating of 5 A per contact. The unit operates within a temperature range of -40°C to +105°C and employs solder pin termination.

Edgeboard Connectors Procurement Notes

Verify the complete part number including all suffixes against official EDAC documentation to ensure correct specifications. Confirm that the required quantity aligns with manufacturer packaging standards, typically supplied in boxes of 25 units. Check regional availability status as distribution may vary by location. Ensure compatibility with existing PCB layout dimensions and mounting hole patterns before procurement.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge interface with 48 positions is required. Verify that the host PCB thickness falls within the acceptable range of 1.37 mm to 1.78 mm. Ensure the application environment remains within the -40°C to +105°C operational limits. Confirm that the panel mount style with threaded insert flanges matches the mechanical assembly requirements.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which defines standard card edge connectors with specific dimensional and electrical characteristics. The series utilizes a consistent 3.96 mm pitch across various position counts. The 305-048 variant specifically addresses applications requiring 48 connection points in a dual-row arrangement, maintaining compatibility with standard half-pitch card edge geometries.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 305 series parts sharing identical 48-position, 3.96 mm pitch, and dual-row specifications. Verify mechanical fit including flange dimensions and mounting hole alignment. Ensure electrical ratings match or exceed original requirements. Consult official substitution guides for equivalent components from other manufacturers if necessary.
