306-012-521-112

Edgeboard Connectors Overview

The EDAC Inc. 306-012-521-112 is a dual female card edge connector from the 306 series, designed for board-to-board or backplane interconnections. It features 24 positions arranged in two rows of twelve contacts, with a centerline spacing of 0.156 inches (3.96 mm). The connector utilizes PC tail termination for through-hole mounting and employs gold-plated copper alloy contacts to ensure reliable signal transmission. The housing is constructed from thermoplastic material, providing structural integrity and electrical insulation. This component supports standard PCB thicknesses and operates within a defined temperature range, making it suitable for various electronic assemblies requiring robust edgeboard connectivity.

Edgeboard Connectors Feature Summary

• Dual female contact configuration provides secure mating with corresponding male edge cards
• Gold-plated copper alloy contacts offer corrosion resistance and low contact impedance
• PC tail termination style enables reliable soldering to printed circuit boards
• Thermoplastic insulator housing ensures mechanical stability and dielectric strength

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required 24-position dual-row configuration and 0.156-inch pitch before ordering. Confirm compatibility with the target PCB stack-up and soldering process requirements. Ensure that the gold plating specification meets the application's conductivity needs. Check for any environmental certifications such as RoHS compliance if required by the end product regulations. Cross-reference the datasheet dimensions against the mechanical design constraints of the enclosure.

Edgeboard Connectors Selection Notes

Select this connector when a 3.96 mm pitch is necessary for high-density routing without compromising signal integrity. The dual female design is ideal for applications where the card edge acts as the male counterpart. Consider the operating temperature range and thermal cycling requirements during selection. Evaluate the mechanical retention needs, as this model relies on solder joint strength rather than panel-mount hardware. Compare against alternative pitches if space constraints allow for tighter spacing options.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series, which specializes in card edge connectors with a 0.156-inch contact spacing. The series offers various position counts and termination styles to accommodate different board densities. The 306-012 variant specifically addresses applications requiring 24 connections in a compact footprint. It complements other EDAC products by providing standardized interface solutions for modular electronic systems.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other EDAC 306 series parts with identical pin counts and pitch but different termination lengths or flange configurations. Verify that any replacement maintains the same 0.156-inch centerline spacing and dual female contact arrangement. Ensure that the substitute part shares the same gold plating thickness and material composition to preserve electrical performance characteristics.
