305-076-521-208

Edgeboard Connectors Overview

The EDAC 305-076-521-208 is a standard card edge connector featuring 76 positions arranged in a dual row configuration. It utilizes a contact spacing of 3.96 mm (0.156 inches) and accommodates printed circuit boards with a nominal thickness of 1.57 mm (0.062 inches). The component provides a continuous current rating of 5 A and withstands 1800 VACrms dielectric voltage. Constructed with copper alloy contacts finished with gold plating, the housing is made from green thermoplastic polyester. Designed for vertical panel mount installation via solder pin termination, it operates within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the official EDAC datasheet to confirm exact termination style and flange characteristics. Ensure compatibility with the target PCB stack-up and mating card thickness specifications before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to confirm current availability status and lead times. Confirm RoHS compliance requirements match project environmental standards.

Edgeboard Connectors Selection Notes

Select this connector when a 76-position dual-row interface is required with a 3.96 mm pitch. It is suitable for applications demanding a 5 A current rating and vertical panel mounting. Consider the 1.57 mm board thickness tolerance and polarizing key acceptance features during mechanical design. Evaluate the operating temperature range and insulation resistance against system environmental constraints.

Edgeboard Connectors Part Context

This component belongs to the EDAC 305 series of standard card edge connectors. The series is characterized by its 3.96 mm contact spacing and robust thermoplastic housing. It represents a solution for high-pin-count vertical interconnections in industrial and commercial electronic assemblies, offering standardized dimensions for widespread compatibility.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical position counts and spacing, such as variations in termination style or flange options. Verify mechanical footprint and electrical ratings before substituting with components from other manufacturers.
