305-050-521-502

Edgeboard Connectors Overview

The EDAC Inc. 305-050-521-502 is a dual-edge female card edge connector designed for board-to-board or backplane interconnections. It features 50 positions with a contact spacing of 0.156 inches (3.96mm) and a row spacing of 0.140 inches (3.56mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm). Constructed with copper alloy contacts finished in gold plating, it utilizes a thermoplastic insulator body. The component supports solder pin termination and operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target board thicknesses and mating requirements. Ensure that the ordering suffix matches the desired contact finish and insulation material specifications. Cross-reference the manufacturer's latest datasheet to validate environmental ratings and compliance standards such as RoHS before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-edge interface with 0.156-inch pitch is required for standard 0.062-inch thick boards. Consider the operating temperature range and current carrying capacity relative to the application's electrical load. Evaluate the mechanical stability provided by the solder tail termination against vibration and shock conditions present in the deployment environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations to support diverse electronic assembly needs. The 305-050-521-502 variant specifically addresses applications needing a 50-position dual-row interface with high reliability and standardized dimensions for consistent manufacturing integration.

Edgeboard Connectors Replacement Considerations

Consult EDAC technical resources for verified substitute part numbers within the same series or compatible alternatives from other manufacturers. Ensure that any replacement maintains identical pitch, row count, and board thickness acceptance criteria to preserve mechanical fit and electrical performance.
