Overview
The EDAC Inc. 306-028-400-104 is a dual-edge female card edge connector featuring a 0.156-inch (3.96mm) contact spacing and 56 positions. Designed for vertical panel mount installation, it utilizes gold-plated copper alloy contacts with a solder pin termination. The housing is constructed from green polyphenylene sulfide (PPS), rated for operation between -40°C and +125°C. It accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57mm) and provides an insulation resistance of 5 GOhms.
Feature Summary
- Dual-edge female configuration with cantilever contact type for secure board retention
- Low-profile insulator body designed to accept standard 0.062-inch nominal thickness PCBs
- Gold-plated copper alloy contacts ensure reliable signal transmission and corrosion resistance
- Vertical panel mount style with flush mount flange features for stable structural integration
Applications
- Industrial control systems requiring robust card edge interfaces
- Communication equipment backplanes and modular assemblies
- Medical device internal connectivity solutions
- Consumer electronics hardware modules
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact plating, housing color, and flange specifications. Ensure the selected variant matches the required PCB thickness tolerance and mounting orientation. Cross-reference the part number with official distributor catalogs to confirm availability status and compliance certifications such as RoHS before finalizing procurement orders.
Selection Notes
Select this component when a dual-edge interface with 0.156-inch pitch is required for vertical panel mounting. Confirm that the application environment falls within the specified temperature range of -40°C to +125°C. Verify that the target PCB thickness aligns with the 0.062-inch design specification. Consider the gold plating requirement for contact durability and the PPS material properties for thermal stability during assembly.
Part Context
This connector belongs to the EDAC 306 series, which specializes in card edge connectors with 0.156-inch spacing. The series offers various position counts and mounting styles to support diverse electronic assembly needs. The 306-028-400-104 specifically addresses applications requiring a 56-position dual-edge interface with vertical panel mounting capabilities and high reliability standards.
Replacement Considerations
Consult the official EDAC substitution guide or datasheet for confirmed equivalent part numbers. Verify compatibility regarding pitch, position count, and mounting style before replacing. Generic cross-references may not match specific flange or termination requirements.
