305-054-556-201

Edgeboard Connectors Overview

The EDAC Inc. 305-054-556-201 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 54 positions arranged in two rows with a 3.96 mm (0.156 inch) pitch. The contacts are made of copper alloy with gold plating and utilize a semi-beekeeper termination style. Rated for 5 A current, it supports PCB thicknesses between 1.37 mm and 1.78 mm. The insulator is green thermoplastic polyester, UL 94V-0 rated, ensuring reliable performance across an operating temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against the manufacturer's official ordering guide to confirm exact pin count, termination type, and mounting orientation. Ensure compatibility with the target PCB thickness specifications before procurement. Cross-reference the RoHS compliance status with current regulatory requirements for the intended market. Confirm that the gold plating thickness meets the application's cycle life expectations.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 3.96 mm pitch is required. The 54-position capacity suits applications needing moderate I/O density. Verify that the panel mount or vertical installation style aligns with the mechanical design constraints. Ensure the 5 A current rating is sufficient for the load conditions. Consider the operating temperature range if the environment exceeds standard commercial limits.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which offers various position counts and mounting options.
