302-012-656-201

Edgeboard Connectors Overview

The EDAC Inc. 302-012-656-201 is a standard card edge connector from the 302 series, designed for non-specified dual-sided cards. It features 12 positions with a 0.050-inch (1.27mm) contact spacing and utilizes gold-plated contacts. The connector employs a cantilever contact type with extender board tails for termination. It is housed in black polyamide (PA66) insulation and supports a card thickness range of 0.051 to 0.071 inches.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix to confirm the contact finish. While some listings describe this part as having gold plating, official specifications for the 302-012-656-201 variant indicate a Tin (Sn) finish with a Nickel (Ni) barrier. Ensure the selected component matches the required conductivity and corrosion resistance for the target application before procurement.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-sided card edge interface is required with a fine 1.27mm pitch. The extender tail design facilitates automated assembly processes. Confirm that the target PCB layout accommodates the specific footprint requirements of the cantilever contact style and verify compatibility with the intended card thickness range.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 Series, which specializes in high-density card edge connectors. The series is characterized by its compact form factor and versatile mounting options, catering to applications requiring robust electrical connections in space-constrained environments. The 302 series offers various pin counts and contact finishes to suit diverse engineering needs.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include the 302-012-256-201, which shares identical mechanical dimensions but differs in contact finish. When replacing, ensure the new part's contact material meets the electrical performance requirements of the circuit.
