302-120-356-201

Edgeboard Connectors Overview

The EDAC Inc. 302-120-356-201 is a standard card edge connector from the 302 Series, designed for non-specified dual-edge circuit boards. It features 120 positions with female contacts arranged in two rows of sixty. The contact spacing is 0.050 inches (1.27mm), and the connector body is black. Contacts are gold-plated copper alloy with a cantilever spring design, ensuring reliable engagement. The housing is constructed from polyamide (PA66) nylon. It supports board thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). The component operates within a temperature range of -55°C to 85°C and utilizes a solder termination method for secure PCB mounting.

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm exact pin count, contact plating specifications, and termination style. Ensure compatibility with the target printed circuit board thickness and edge profile requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a high-density interface with 0.050-inch spacing is required for dual-edge cards. Confirm that the application environment stays within the specified -55°C to 85°C operating range. Validate that the cantilever contact force meets the mechanical retention needs of the assembly.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 Series, which specializes in low-profile card edge connectors. The series provides various position counts and spacing options for diverse electronic packaging needs. The 302-120 variant specifically addresses high-pin-count requirements while maintaining a compact footprint suitable for dense board layouts.

Edgeboard Connectors Replacement Considerations

Direct substitutes include other EDAC 302 Series parts with matching 120-position configurations and 0.050-inch spacing. Verify that any alternative part maintains identical contact type, termination method, and insulation material properties for seamless integration.
