306-013-421-178

Edgeboard Connectors Overview

The EDAC Inc. 306-013-421-178 is a standard card edge connector receptacle featuring 26 positions arranged in a dual-edge 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 a tin plating finish, rated for 5 A current. The insulator body is made of thermoplastic polyester and is green in color, operating within a temperature range of -40°C to +105°C.

Edgeboard Connectors Procurement Notes

Verify the specific suffix code against the manufacturer's official ordering guide to ensure correct contact plating and material specifications. Confirm that the target PCB thickness falls within the accepted range of 0.054 to 0.070 inches. Check RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the supplier provides valid traceability documentation for the copper alloy contacts and thermoplastic polyester housing materials.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge connection is required for a 26-position interface with a 3.96 mm pitch. The through-hole mounting style suits applications requiring robust mechanical anchoring. The tin plating offers cost-effective conductivity suitable for general-purpose environments. Consider the low-profile body height if vertical space constraints exist on the assembly panel.

Edgeboard Connectors Part Context

This part belongs to the EDAC 306 Series, a line of standard card edge connectors known for their versatility in various electronic assemblies. The series supports multiple position counts and mounting styles, catering to diverse industry needs. The 306-013-421-178 specifically addresses the need for a mid-range position count with dual-edge accessibility, fitting into the broader portfolio of EDAC's interconnect solutions.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include parts with identical pin counts and spacing but different suffixes for plating variations, such as 306-013-421-104 or 306-013-421-103. Verify mechanical compatibility before swapping, as housing dimensions must remain consistent.
