306-016-520-158

Edgeboard Connectors Overview

The EDAC Inc. 306-016-520-158 is a dual-edge female card edge connector from the 306 series, designed for through-hole mounting. It features 32 positions with a 0.156-inch (3.96mm) contact spacing and a 0.200-inch (5.08mm) row pitch. The contacts are gold-plated copper alloy cantilever springs, ensuring reliable signal transmission. The insulator is made of green thermoplastic material, rated for operation between -40°C and 105°C. It supports board thicknesses from 0.054 to 0.070 inches and includes flange features for secure panel installation.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with cantilever spring contacts for robust board insertion
• Gold-plated terminals provide corrosion resistance and stable electrical performance
• Green thermoplastic insulator ensures durability across specified temperature ranges
• Flanged design facilitates secure mounting with side openings for fastener access

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics module connections
• Medical device circuit board interfaces

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact spacing and insulation color. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the package quantity meets assembly requirements without compromising component integrity during storage. Cross-reference the manufacturer part number against distributor listings to confirm authenticity and current availability status before finalizing purchase orders.

Edgeboard Connectors Selection Notes

Select this connector when a 0.156-inch pitch dual-edge interface is required for high-reliability applications. Evaluate the thermal rating to ensure compatibility with operating environments up to 105°C. Consider the mechanical flange specifications for proper panel cutout dimensions. Verify that the target PCB thickness falls within the supported range of 0.054 to 0.070 inches for optimal contact engagement and mechanical stability.

Edgeboard Connectors Part Context

This component belongs to the EDAC 306 series of card edge connectors, which are engineered for demanding industrial and commercial environments. The series offers various pin counts and spacing options to accommodate diverse board designs. The 306-016-520-158 variant specifically addresses needs for moderate-density connections with durable gold plating and standardized mounting features, fitting into broader system architectures requiring reliable vertical or horizontal board-to-board interfaces.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 0.156-inch pitch, 32-position count, and dual-edge female configuration. Verify that alternative components maintain identical flange dimensions and thermal ratings. Check for compatible termination methods and insulation materials to ensure mechanical and electrical equivalence in existing assemblies.
