305-044-556-208

Edgeboard Connectors Overview

The EDAC Inc. 305-044-556-208 is a standard card edge connector from the 305 series, designed for panel mount applications with a vertical orientation. It features 44 positions arranged in a dual-row configuration with a contact spacing of 3.96 mm (0.156 inches). The connector accepts printed circuit boards with a nominal thickness of 1.57 mm and utilizes gold-plated copper alloy contacts terminated via solder pins. Rated for 5 A current, it operates within a temperature range of -40°C to +105°C and includes an insulator body compatible with specific mounting hardware.

Edgeboard Connectors Procurement Notes

Verify the complete part number including suffix codes against official EDAC documentation to ensure correct pin count, plating specification, and mounting configuration. Confirm RoHS compliance status and operating temperature ratings match project requirements before procurement. Cross-reference datasheet mechanical drawings for panel cutout dimensions and mating board thickness tolerances.

Edgeboard Connectors Selection Notes

Select this component when a 44-position dual-row card edge interface is required with 3.96 mm spacing. Ensure the application supports panel mounting and vertical connection geometry. Verify that the target PCB thickness aligns with the 1.57 mm nominal specification. Consider thermal environment constraints relative to the -40°C to +105°C operational range during selection.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 305 series, which provides standardized card edge solutions for various position counts. The series maintains consistent 3.96 mm pitch across variants, facilitating modular design approaches. The 305-044 variant specifically addresses mid-range density requirements while maintaining compatibility with standard industrial panel mounting practices and mating board specifications.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 305 series connectors with matching 44-position configurations such as 305-044-556-258. Verify identical mechanical dimensions, contact spacing, and termination methods before substitution. Cross-model generic features do not guarantee interchangeability without confirming specific suffix variations.
