306-021-500-108

Overview

The EDAC Inc. model 306-021-500-108 is a standard card edge connector receptacle designed for vertical panel mount installation. It features a dual female configuration with 42 total positions arranged in two rows, providing a contact pitch of 0.156 inches (3.96 mm). The unit utilizes solder pin termination and gold-plated copper alloy contacts to ensure reliable signal transmission. The insulator is constructed from green thermoplastic polyester, accommodating board thicknesses between 0.054 and 0.070 inches (1.37 to 1.78 mm).

Feature Summary

• Dual-edge female contact design accommodates non-specified card types.
• Vertical orientation facilitates direct panel mounting integration.
• Gold-plated copper alloy contacts provide durable electrical interfaces.

Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm exact physical dimensions and plating specifications. Ensure compatibility with the target printed circuit board thickness range of 1.37 to 1.78 mm prior to procurement. Confirm that the vertical panel mount style aligns with the mechanical enclosure requirements of the final assembly.

Selection Notes

Select this component when a dual-row interface with a 3.96 mm pitch is required for high-density applications. The vertical form factor is suitable for chassis-mounted solutions where space efficiency is prioritized. Consider the gold plating for environments requiring corrosion resistance and stable contact impedance over extended operational cycles.

Part Context

This part belongs to the EDAC 306 series, which specializes in standard card edge connectors. The series offers various position counts and row configurations to support diverse electronic module requirements. The 306-021-500-108 specifically addresses needs for dual-edge connectivity with robust mechanical retention.

Replacement Considerations

Direct substitutes within the same series include models such as 306-010-421-108 for single-row variants or 306-021-500-108 equivalents with different row counts. Verify mechanical footprint and pinout consistency before cross-referencing with other manufacturers' offerings.
