305-070-555-203

Edgeboard Connectors Overview

The EDAC Inc. 305-070-555-203 is a standard card edge connector from the 305 series, designed for dual-edge female applications. It features 70 positions with a contact spacing of 0.156 inches (3.96 mm) and a row spacing of 0.140 inches (3.56 mm). The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Constructed with copper alloy contacts that are gold-plated, it provides a continuous current rating of 5 A. The housing is made of green thermoplastic polyester, offering an insulation resistance of 5 GOhms. It supports a temperature range of -40°C to +105°C and utilizes a solder termination type.

Edgeboard Connectors Feature Summary

Edgeboard Connectors Procurement Notes

Verify the specific suffix codes against official EDAC documentation to confirm exact plating thickness and flange configurations. Ensure compatibility with the target PCB thickness of 1.57 mm before integration. Cross-reference the RoHS status and REACH compliance requirements with current regulatory standards for the intended market. Confirm that the solder termination method aligns with the assembly process capabilities.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 70 positions is required. The 3.96 mm pitch suits applications needing moderate density without excessive miniaturization. Verify that the 5 A current rating meets the electrical load requirements. Consider the operating temperature range of -40°C to +105°C for environmental suitability. Ensure the mechanical fit allows for the specified board thickness and mounting style.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 series of standard card edge connectors. The series offers various position counts and configurations for dual-edge applications. Components in this family share common design principles, including gold-plated copper alloy contacts and thermoplastic polyester housings. The 305 series is widely used in industries requiring reliable, high-density connections for vertical or straight panel installations.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the EDAC 305 series include parts with identical pin counts and pitch, such as 305-070-521-202 variants if flange differences are acceptable. Verify mechanical dimensions and electrical ratings before substitution. Consult official cross-reference guides for approved alternatives.
