306-022-400-104

Overview

The EDAC Inc. 306-022-400-104 is a standard card edge connector from the 306 series, designed for reliable signal transmission in electronic assemblies. It features a dual female configuration with 44 positions arranged in two rows, utilizing a 3.96 mm (0.156 inch) contact spacing. The connector employs copper alloy contacts with tin plating to ensure durability and conductivity. It is engineered for board-to-board connections, supporting a current rating of 5 A and operating within a temperature range of -40°C to +105°C. The housing is constructed from thermoplastic polyester, providing mechanical stability and insulation.

Feature Summary

• Dual edge female design accommodates double-sided circuit boards for increased I/O density
• Tin-plated copper alloy contacts provide corrosion resistance and reliable electrical performance
• Thermoplastic polyester housing offers structural integrity and high insulation resistance

Applications

• Industrial control systems requiring robust board-to-board interconnects
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement instrumentation needing high-density signal paths

Procurement Notes

Verify component authenticity through authorized EDAC distributors or certified suppliers. Confirm RoHS compliance status via official datasheets before integration. Ensure storage conditions maintain material integrity, as humidity can affect plastic housing properties. Cross-reference part numbers carefully to avoid confusion with similar series variants that may differ in pin count or plating specifications.

Selection Notes

Select this model when dual-edge connectivity is required for space-constrained applications. The 3.96 mm pitch suits standard PCB layouts while maintaining signal isolation. Tin plating is suitable for general-purpose environments but may require consideration for high-wear mating cycles compared to gold options. Evaluate thermal requirements against the specified operating range to ensure long-term reliability in the target application environment.

Part Context

This component belongs to the EDAC 306 series, which specializes in standard card edge connectors for various industrial and commercial electronics. The series is known for its versatility in handling different board thicknesses and contact configurations. The 306-022-400-104 variant specifically addresses needs for higher pin counts in a dual-row format, making it a common choice for complex digital circuits.

Replacement Considerations

Direct substitutes include other EDAC 306 series connectors with matching 44-position dual-edge specifications. Verify identical pin pitch, housing material, and contact plating to ensure mechanical and electrical compatibility. Alternative manufacturers may offer functionally equivalent parts, but dimensional tolerances and mounting hole patterns must be strictly validated against original PCB footprints.
