306-035-400-103

Overview

The EDAC Inc. 306-035-400-103 is a dual-edge female card edge connector designed for panel mounting. It features 70 positions arranged in two rows with a 0.156-inch (3.96mm) spacing. The contacts are made of copper alloy with tin plating and utilize a cantilever spring termination method for solder hole end termination. The housing is green thermoplastic polyester, rated for operation between -40°C and 105°C. It supports non-specified dual-edge cards with thicknesses ranging from 0.054 to 0.070 inches.

Feature Summary

• Dual-edge female contact configuration for secure board insertion
• Cantilever spring contact design ensures reliable electrical connection
• Panel mount installation with flush flange characteristics
• Tin-plated copper alloy contacts for corrosion resistance

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics motherboard connections
• Medical device circuit board interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official 306 Series Ordering Guide to ensure correct contact plating and housing color specifications. Confirm that the target PCB layout matches the 0.156-inch pitch and panel mounting requirements. Check RoHS compliance status if restricted substances are a project constraint. Ensure the selected variant aligns with the required card thickness range of 0.054 to 0.070 inches for proper mechanical retention.

Selection Notes

Select this component when a high-density dual-edge interface is required for panel-mounted applications. The 70-position count suits complex signal routing needs. Consider the tin plating option for cost-effective solutions where gold plating is not strictly necessary for conductivity or wear resistance. Verify that the operating temperature range of -40°C to 105°C meets environmental demands. Ensure the housing material compatibility with adjacent components in the assembly.

Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for robust mechanical performance. The series offers various position counts and termination options to accommodate diverse board designs. The 306-035-400-103 specifically addresses the need for a 70-position dual-edge solution with panel mounting capabilities, fitting into broader industrial and commercial electronic systems requiring reliable interconnects.

Replacement Considerations

Consult the EDAC 306 Series cross-reference documentation for direct substitutes. Alternative parts must match the 0.156-inch pitch, 70-position count, and dual-edge female configuration. Verify that any replacement maintains the same panel mount style and thermal rating. Ensure contact material and plating specifications are compatible with the application's electrical requirements.
