306-017-521-178

Edgeboard Connectors Overview

The EDAC Inc. 306-017-521-178 is a standard card edge connector receptacle featuring 34 positions arranged in a dual configuration. It utilizes a 0.156-inch (3.96 mm) contact spacing and is designed for through-hole mounting with a straight orientation. The connector accepts printed circuit boards with a nominal thickness of 0.062 inches (1.57 mm). Contacts are constructed from copper alloy with gold plating, rated for 5 A current. The insulator body is made of thermoplastic polyester.

Edgeboard Connectors Feature Summary

• Dual female contact configuration for secure board insertion
• Gold-plated copper alloy contacts ensure reliable signal transmission
• Low-profile insulator body design for space-constrained applications
• Through-hole solder termination for robust mechanical attachment

Edgeboard Connectors Applications

• Industrial control systems requiring high-reliability interconnects
• Communication equipment backplanes and modules
• Medical device internal circuit board connections
• Consumer electronics assembly lines

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm contact spacing, board thickness compatibility, and mounting style. Ensure the procurement specification matches the required 3.96 mm pitch and 1.57 mm board thickness. Confirm RoHS compliance status if restricted substances are mandated by the end product regulations. Cross-reference the manufacturer part number with official EDAC documentation to avoid substitution errors.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with 34 positions is required. Ensure the mating PCB has a thickness within the specified tolerance range. Verify that the application environment does not exceed the thermal limits of the thermoplastic polyester insulator. Consider the straight mounting angle for panel or board-to-board integration needs.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 series of card edge connectors. The series offers various position counts and configurations. The 306 series is characterized by its low-profile design and use of thermoplastic polyester materials. It provides a standardized solution for connecting double-sided PCBs in various electronic assemblies.

Edgeboard Connectors Replacement Considerations

Consult official EDAC documentation for confirmed substitute part numbers. Do not assume cross-compatibility with other manufacturers' products without verifying pinout, pitch, and mechanical dimensions.
