305-050-555-202

Edgeboard Connectors Overview

The EDAC Inc. model 305-050-555-202 is a standard card edge connector from the 305 series, designed for dual-edge female connections. It features 50 positions with a 3.96 mm (0.156 inch) pitch and supports two rows of contacts. The connector accommodates board thicknesses ranging from 1.37 mm to 1.78 mm (0.054 to 0.070 inches). Constructed with copper alloy contacts finished in gold, it provides a continuous current rating of 5 A. The housing is made of green thermoplastic polyester, ensuring reliable insulation. Operating temperatures range from -40°C to +105°C, with an insulation resistance of 5 GOhms.

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and material variations. Ensure compatibility with target PCB thickness specifications before integration. Confirm RoHS compliance status through manufacturer datasheets. Validate mounting hole dimensions against mechanical design constraints. Check for updated environmental declarations if required by project standards.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 50 positions is required. The 3.96 mm pitch suits applications needing wider spacing between contacts. Consider the straddle mount style for panel-mounted solutions. Verify that the 5 A current rating meets circuit requirements. Ensure the operating temperature range aligns with environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of card edge connectors, which offer various mounting options and row configurations. The series is known for accepting polarizing keys for alignment. Similar parts in the series vary by position count and termination type. The 305 series provides standardized dimensions for interoperability within industrial and commercial electronic assemblies.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 305 series variants with matching 50-position counts and 3.96 mm pitch. Verify mechanical fit and electrical ratings before substitution. Cross-reference with manufacturer cross-reference guides for equivalent components from other suppliers.
