306-035-421-104

Overview

The EDAC Inc. 306-035-421-104 is a dual female card edge connector from the 306 series, designed for panel and through-hole mounting. It features 86 positions with a 0.156-inch (3.96mm) contact spacing arranged in two rows of 43 contacts each. The connector utilizes copper alloy cantilever contacts with tin plating and a green thermoplastic polyester insulator. It accepts printed circuit boards with thicknesses ranging from 0.054 to 0.070 inches (1.37mm to 1.78mm). The unit supports a working temperature range of -40°C to 105°C and includes flange features for flush installation.

Feature Summary

• Dual female configuration with cantilever contact type for reliable board insertion
• Flush mount flange design with top opening for secure panel integration
• Tin-plated copper alloy contacts housed in green thermoplastic polyester insulation

Applications

• Industrial control systems requiring robust card edge interfaces
• Communication equipment utilizing standard PCB thicknesses
• Consumer electronics assemblies needing high-density connections

Procurement Notes

Verify the specific part number against official EDAC documentation to confirm compatibility with target PCB thicknesses within the 0.054 to 0.070 inch range. Ensure that the tin-plated contact finish meets environmental requirements for the intended application. Confirm that the dual female configuration aligns with the mating card edge design. Check RoHS compliance status if restricted substances are a concern for the project specifications.

Selection Notes

Select this component when a dual-sided connection is required for thicker PCBs up to 0.070 inches. The 0.156-inch spacing allows for higher pin counts compared to finer pitch alternatives. Consider the through-hole termination method for mechanical stability. Evaluate the operating temperature range against environmental conditions. Verify that the green insulator color does not conflict with aesthetic or identification standards.

Part Context

This connector belongs to the EDAC 306 series, which offers various position counts and configurations. The 306-043-421-104 shares similar structural characteristics but differs in position count. The series is known for providing standardized solutions for edgeboard applications. EDAC manufactures these components to meet specific industry requirements for durability and electrical performance.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Cross-reference with other EDAC 306 series variants only if dimensional and electrical parameters match exactly. Verify supplier-specific equivalents carefully to ensure interface compatibility.
