305-042-556-203

Edgeboard Connectors Overview

The EDAC Inc. 305-042-556-203 is a standard card edge connector from the 305 series, designed for dual-edge board applications. It features 42 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses between 0.054 and 0.070 inches. The connector utilizes gold-plated copper alloy contacts with a 10.0 µin thickness, housed in a green thermoplastic polyester body. Rated at 5 A, it supports vertical panel mounting via solder lug termination 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 confirm exact plating thickness, flange specifications, and packaging quantity. Ensure compatibility with the target PCB edge thickness and panel cutout dimensions before procurement. Cross-reference the RoHS status and material declarations with current regulatory requirements for the intended market.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for high-density signal routing. The 3.96 mm pitch accommodates larger gauge traces compared to finer pitches. Verify that the 5 A current rating meets the circuit load requirements. Consider the vertical panel mounting style if space constraints on the PCB surface are critical.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and termination styles. The 305-042 variant specifically addresses applications requiring 42 connections with a standardized 0.156-inch spacing, balancing density and mechanical stability for industrial environments.
