306-035-420-107

Overview

The EDAC Inc. model 306-035-420-107 is a standard card edge connector designed for vertical panel mounting applications. It features a dual female configuration with 70 positions arranged in two rows. The connector utilizes a 3.96 mm (0.156 inch) contact spacing and accepts printed circuit boards with a thickness range of 1.37 mm to 1.78 mm. Constructed with copper alloy contacts featuring gold plating, it provides a current rating of 5 A and an insulation resistance of 5 GOhms. The insulator body is made from thermoplastic polyester, ensuring durability within an operating temperature range of -40°C to 105°C.

Feature Summary

• Dual female contact configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable conductivity
• Thermoplastic polyester housing offers thermal stability
• Vertical panel mount design facilitates structured installation

Applications

• Industrial control system interconnections
• Telecommunications equipment backplanes
• Test and measurement instrument interfaces
• Automotive electronics module connections

Procurement Notes

Verify the specific ordering suffix to confirm contact termination type and flange characteristics, as variations exist within the 306 series. Ensure compatibility with the target PCB thickness specifications before procurement. Confirm RoHS compliance status if required by project regulations. Cross-reference the manufacturer datasheet for precise dimensional tolerances and mating force requirements to prevent assembly issues.

Selection Notes

Select this component when a high-density dual-row interface is required for thick PCBs up to 1.78 mm. The 3.96 mm pitch suits applications where space efficiency is balanced with robust mechanical retention. Consider the vertical orientation for panel integration needs. Evaluate the 5 A current rating against load requirements. Verify that the gold plating meets environmental corrosion resistance standards for the intended operational lifespan.

Part Context

This part belongs to the EDAC 306 Series of standard card edge connectors, which are characterized by their low-profile insulator bodies and acceptance of nominal 1.57 mm thick PCBs. The series offers various position counts and termination options. The 306-035-420-107 specifically addresses the need for 70-position connectivity in dual-row configurations, fitting into the broader ecosystem of EDAC's industrial-grade interconnect solutions.

Replacement Considerations

Direct substitutes within the same series include models with identical pin counts and pitch but different termination styles, such as 306-035-521-107. Verify mechanical footprint and electrical ratings before substitution. Generic equivalents may lack the specific flange or mounting features documented for this EDAC part.
