306-026-521-103

Overview

The EDAC Inc. 306-026-521-103 is a dual female card edge connector designed for high-density interconnect applications. It features 52 positions with a contact spacing of 0.156 inches (3.96 mm). The component utilizes gold-plated contacts to ensure reliable signal transmission and low contact resistance. It is engineered to accept printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). The insulator body is constructed from green material, providing visual identification and standard insulation properties suitable for general electronic assembly requirements.

Feature Summary

• Dual female configuration supporting single centerline row architecture
• Gold-plated contact surfaces for enhanced conductivity and durability
• Low profile insulator body design for compact board integration
• Compatible with standard 0.062 inch nominal thickness PCBs

Applications

• High-density computing system backplanes
• Industrial control module interconnections
• Telecommunications network interface cards
• Medical device internal circuit board linking

Procurement Notes

Verify the specific ordering suffix against official EDAC documentation to confirm exact pin count, plating specifications, and board thickness compatibility. Ensure that the procurement source provides valid manufacturer traceability and original packaging integrity. Cross-reference the part number with current datasheets to confirm availability of updated environmental compliance certifications prior to finalizing purchase orders.

Selection Notes

Select this connector when a dual-sided female interface is required for rigid board insertion. Confirm that the target application supports the 0.156-inch pitch dimension and that the PCB stack-up allows for the specified 0.062-inch thickness tolerance. Evaluate mechanical retention needs as this is a non-specified style connector without integrated locking mechanisms beyond friction fit.

Part Context

This component belongs to the EDAC 306 series of card edge connectors, a line established for robust rack and panel solutions. EDAC has specialized in these interconnect systems since 1966, focusing on complex designs for global OEMs. The 306 series specifically targets applications requiring reliable dual-edge mating interfaces in demanding environments across computing and industrial sectors.

Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Users must verify dimensional compatibility and electrical ratings if considering alternative manufacturers or different EDAC series parts.
