302-022-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-022-321-201 is a card edge connector from the 302 Series, designed for board edge mounting with a cantilever contact type. It features a dual-edge configuration with 22 positions and two rows of contacts, providing a total of 44 connection points. The pitch is 0.050 inches (1.27mm), and it accepts card thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). The contacts are gold-plated copper alloy, housed in a black polyamide (PA66) insulator. Rated for operation between -55°C and 85°C, it utilizes a solder termination method.

Edgeboard Connectors Procurement Notes

Verify the specific part number against official EDAC Inc. documentation to confirm pin count, spacing, and termination style. Ensure compatibility with target card thickness specifications before procurement. Check RoHS compliance status and moisture sensitivity level requirements for assembly processes. Confirm package quantity matches production needs without relying on distributor estimates.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with 1.27mm pitch is required. Verify that the mating card thickness falls within the 1.30mm to 1.80mm range. Consider the operating temperature range and material composition for environmental suitability. Compare against other 302 series variants if different position counts or contact finishes are needed.

Edgeboard Connectors Part Context

This connector belongs to the EDAC 302 Series, which specializes in standard card edge connectors with 0.050-inch spacing. The series offers various configurations for board-to-board or backplane connections. Components in this line are characterized by their cantilever contact design and durable polymer housing, suitable for general-purpose electronic assemblies.

Edgeboard Connectors Replacement Considerations

Cross-reference with other EDAC 302 series parts for alternative position counts. Verify functional equivalence only if datasheet parameters match exactly. Do not assume interchangeability with different series or manufacturers without detailed electrical and mechanical validation.
