305-084-556-503

Edgeboard Connectors Overview

The EDAC Inc. model 305-084-556-503 is a standard card edge connector from the 305 series, designed for high-density interconnect applications. It features an 84-position dual-row configuration with a contact spacing of 3.96 mm and a row spacing of 3.56 mm. The unit accepts printed circuit boards with a nominal thickness of 1.57 mm and utilizes gold-plated copper alloy contacts to ensure reliable signal transmission. Rated for 5 A continuous current and 1800 VACrms dielectric voltage, it operates within a temperature range of -40°C to +105°C. The connector employs a solder pin termination style and includes panel mount vertical installation capabilities.

Edgeboard Connectors Procurement Notes

Verify the specific manufacturer part number against official EDAC documentation to confirm compatibility with required PCB thicknesses and mounting configurations. Ensure that the selected variant matches the necessary current ratings and environmental operating conditions for the intended application. Cross-reference datasheets to validate termination styles and contact plating specifications before procurement.

Edgeboard Connectors Selection Notes

Select this component based on the requirement for an 84-position dual-row interface with a 3.96 mm pitch. Confirm that the design accommodates the specified 1.57 mm board thickness and vertical panel mounting constraints. Evaluate thermal requirements against the -40°C to +105°C operational range and verify that the 5 A current rating meets the circuit load demands.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors, which are engineered for durable and reliable connectivity in demanding environments. The series offers various position counts and mounting options, maintaining consistent electrical performance standards across different configurations while supporting precise mechanical alignment through standardized dimensions.

Edgeboard Connectors Replacement Considerations

Consult official EDAC substitution guides or distributor cross-reference tools to identify compatible alternatives. Verify that any substitute maintains identical pin counts, pitch dimensions, and termination methods to ensure mechanical and electrical interchangeability without redesigning the host assembly.
