305-044-556-212

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-212 is a standard card edge connector header featuring 44 positions arranged in a dual-row configuration. It utilizes a 3.96 mm (0.156 inch) contact pitch with a row spacing of 3.56 mm (0.140 inch). Designed for panel mount installation at a vertical angle, the unit accepts printed circuit boards with a nominal thickness of 1.57 mm (0.062 inch). The contacts are constructed from copper alloy and feature gold plating to ensure reliable signal transmission. Rated for 5 A current, the connector employs a thermoplastic polyester insulator body and terminates via solder pins.

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 44-position dual-row configuration and 3.96 mm pitch before procurement. Confirm compatibility with 1.57 mm PCB thickness to ensure proper mechanical fit. Check for RoHS compliance requirements if operating in regulated environments. Ensure the gold plating specification meets the intended conductivity and wear resistance standards for the application.

Edgeboard Connectors Selection Notes

Select this component when a robust, dual-row card edge interface is required for 1.57 mm thick boards. The 3.96 mm pitch allows for sufficient spacing between traces compared to finer pitches. The vertical panel mount orientation is suitable for applications requiring direct chassis insertion. Consider the 5 A current rating and gold contact material for long-term reliability in demanding operational conditions.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series offers various position counts and mounting options tailored for diverse electronic assembly needs. The 305-044-556-212 variant specifically addresses applications requiring a moderate density connection with durable metal contacts and a thermoplastic housing for structural integrity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 305-048-520-212 and 305-054-556-278, though these differ in position count. Verify that any replacement maintains the 3.96 mm pitch and 1.57 mm board thickness compatibility. Cross-reference pinout configurations and mounting hole patterns to ensure mechanical interchangeability without redesigning the host panel.
