306-035-500-103

Overview

The EDAC Inc. 306-035-500-103 is a dual-edge female card edge connector from the 306 series, designed for panel mounting. It features 70 positions with a 0.156-inch (3.96mm) pitch across two rows. The contacts are gold-plated copper alloy with a thickness of 10.0µin (0.25µm). It accommodates card thicknesses between 0.054" and 0.070" (1.37mm - 1.78mm). The insulator is green thermoplastic polyester, and it includes flush mount flanges with floating bobbins (0.116" diameter). Operating temperature ranges from -40°C to 105°C.

Feature Summary

• Dual-edge configuration with 70 total positions for high-density signal routing
• Floating bobbin flange design ensures secure alignment and strain relief during insertion
• Gold contact plating provides reliable conductivity and corrosion resistance
• Thermoplastic polyester insulation supports operation in temperatures up to 105°C

Applications

• Industrial control systems requiring robust board-to-board connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing durable interconnects
• Automotive electronics modules operating in varied thermal environments

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact physical dimensions and termination style. Ensure compatibility with the target PCB card thickness range of 0.054" to 0.070". Confirm that the flush mount flange design aligns with the enclosure requirements. Check for RoHS3 compliance status if environmental regulations apply to the final assembly.

Selection Notes

Select this component when a dual-edge interface with a 0.156" pitch is required for panel-mounted applications. The floating bobbin feature is critical for maintaining connection integrity under mechanical stress. Compare against single-row alternatives if space constraints allow, but note that this model offers higher pin counts. Ensure the mating card material and thickness fall within the specified operational limits for optimal contact performance.

Part Context

This part belongs to the EDAC 306 series of standard card edge connectors. The series is characterized by its use of thermoplastic polyester insulation and gold-plated contacts. Similar models in the series vary primarily by position count and flange configurations. The 306 series is widely used in general-purpose electronic assemblies where reliable, repeatable connections are necessary.

Replacement Considerations

Direct substitutes may include other EDAC 306 series variants with matching 70-position dual-edge specifications. Verify that any replacement maintains the same 0.156" pitch and compatible flange mounting style. Cross-reference with manufacturer cross-reference guides for equivalent parts from other suppliers offering similar form-fit-function characteristics.
