302-010-321-201

Edgeboard Connectors Overview

The EDAC Inc. 302-010-321-201 is a standard card edge connector from the 302 series, designed for dual-edge board applications. It features 10 positions with a female contact configuration and a 0.050-inch (1.27mm) pitch. The contacts are gold-plated copper alloy cantilever springs, suitable for reliable signal transmission. The housing is black polyamide (PA66), rated for operation between -55°C and +85°C. This through-hole mount connector accommodates card thicknesses of 0.051 to 0.071 inches.

Edgeboard Connectors Feature Summary

• Dual-edge female contact design utilizing cantilever spring terminals for secure board insertion
• Gold flash plating on copper alloy contacts ensures corrosion resistance and low contact impedance
• Polyamide (PA66) insulation housing provides structural stability and thermal resilience
• Through-hole termination method supports robust PCB mounting without requiring additional lugs

Edgeboard Connectors Applications

• Industrial control system interconnects
• Medical device circuit board connections
• Telecommunications equipment backplanes
• Automotive electronic module interfaces

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm contact length and plating specifications. Ensure the selected variant matches the required board thickness range of 0.051 to 0.071 inches. Confirm RoHS3 compliance status if environmental regulations apply to the end product assembly process.

Edgeboard Connectors Selection Notes

Select this component when a low-profile, dual-edge connection is required for thin circuit boards. The 1.27mm pitch allows for high-density routing compared to larger spacing options. Consider the operating temperature range of -55°C to +85°C for suitability in harsh environments. Verify that the through-hole mounting style aligns with the target PCB fabrication capabilities.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 series of standard card edge connectors. The series offers various position counts and contact lengths to accommodate different board thicknesses. The 302 series is characterized by its compact form factor and reliable cantilever contact mechanism, widely used in general-purpose electronic assemblies requiring durable plug-in connectivity.

Edgeboard Connectors Replacement Considerations

Direct substitutes within the same series include 302-006-321-201 for 6 positions and 302-012-321-201 for 12 positions, provided the pin count differs. Cross-series replacements require matching pitch, row count, and mounting type. Verify dimensional compatibility before substituting with other manufacturers' products.
