302-100-221-201

Edgeboard Connectors Overview

The EDAC Inc. 302-100-221-201 is a 100-position female card edge connector from the 302 Series, designed for non-specified dual-edge PCBs. It features a 0.050 inch (1.27mm) contact pitch and accepts board thicknesses between 0.051 and 0.071 inches (1.30 to 1.80mm). The unit utilizes cantilever contacts with gold plating over copper alloy substrates, housed in black polyamide (PA66) insulation. Rated for operation between -55°C and +85°C, it employs a surface-mount termination style.

Edgeboard Connectors Feature Summary

• Dual-edge interface design accommodates non-specified PCB cards
• Cantilever spring contact mechanism ensures reliable engagement
• Gold-plated terminals provide corrosion resistance
• Surface-mount termination facilitates automated assembly

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment modules
• Medical device interconnects
• Automotive electronic control units

Edgeboard Connectors Procurement Notes

Verify that the target printed circuit board thickness falls within the specified 1.30mm to 1.80mm range to ensure proper mechanical fit. Confirm that the manufacturing environment remains within the -55°C to +85°C operational temperature limits. Ensure compatibility with the 0.050-inch pitch requirement during layout planning. Check RoHS3 compliance status against current project regulatory requirements before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a high-density dual-edge connection is required for thin-profile circuit boards. The 0.050-inch pitch allows for significant pin counts within a compact footprint. Consider the surface-mount mounting style if space constraints prevent through-hole implementation. Verify that the black PA66 housing material meets the thermal and chemical resistance needs of the specific application environment.

Edgeboard Connectors Part Context

This part belongs to the EDAC 302 Series, which specializes in low-profile card edge connectors. The series is engineered for applications requiring robust connections on thin PCBs. The 302-100-221-201 variant specifically addresses the need for 100 positions in a dual-row configuration. It complements other series like the 100 and 341 by offering distinct pitch and mounting options.

Edgeboard Connectors Replacement Considerations

Direct substitutes include the 302-100-221-202 and 302-100-221-203 variants, which share identical electrical and mechanical specifications but differ in packaging or minor suffix attributes. Cross-series replacements require careful verification of pitch and board thickness compatibility.
