302-040-358-201

Edgeboard Connectors Overview

The EDAC Inc. 302-040-358-201 is a dual-edge card edge connector from the 302 series, designed for surface-mount or through-hole PCB integration. It features 40 positions with a 0.050-inch (1.27mm) contact pitch and a 0.200-inch (5.08mm) row spacing. The connector utilizes gold-plated cantilever spring contacts housed in black polyamide (PA66) insulation. It supports non-specified dual-edge cards with thicknesses ranging from 0.051 to 0.071 inches (1.30mm to 1.80mm). Operating within a temperature range of -55°C to +85°C, it complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Cantilever spring contact design ensures reliable mating without soldering during insertion.
• Gold-plated terminals provide corrosion resistance and stable electrical conductivity.
• Black polyamide housing offers high thermal stability and mechanical durability.
• Dual-edge configuration accommodates standard non-specified card edge profiles.

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Consumer electronics module interfaces
• Medical device signal routing

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board layout matches the specified 0.050-inch pitch and 0.200-inch row spacing dimensions. Confirm compatibility with the required card edge thickness range of 1.30mm to 1.80mm. Ensure the assembly process aligns with the component's RoHS3 compliance requirements and operating temperature specifications. Cross-reference the manufacturer part number against authorized distributor catalogs to confirm current availability and lead times.

Edgeboard Connectors Selection Notes

Select this model when a low-profile, dual-edge connection is required for non-specified cards. The 0.050-inch pitch allows for dense pin counts in limited board areas. Consider the cantilever contact mechanism for ease of insertion and removal compared to rigid pins. Verify that the black PA66 insulation meets the environmental and thermal requirements of the specific application environment.

Edgeboard Connectors Part Context

This component belongs to the EDAC 302 series, which specializes in standard card edge connectors. The series is characterized by its use of cantilever spring contacts and compact form factors suitable for various electronic assemblies. The 302 series provides options for different pin counts and contact spacings, catering to diverse connectivity needs in modern electronic devices.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 40-position count, 0.050-inch pitch, and dual-edge configuration. Verify that alternative components support the same card thickness range and offer comparable gold plating and material specifications. Consult official cross-reference lists for verified equivalent part numbers from other manufacturers.
