305-016-521-203

Edgeboard Connectors Overview

The EDAC Inc. 305-016-521-203 is a dual-row card edge connector designed for vertical panel mounting. It features 16 positions with a 0.156-inch (3.96 mm) pitch and accepts board thicknesses of 0.062 inches (1.57 mm). The contacts are gold-plated copper alloy with a solder lug termination type, rated for 5 A current. The housing is green thermoplastic, operating between -40°C and +105°C, and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Dual-row configuration with gold-plated copper alloy contacts for reliable signal transmission
• Vertical panel mount design with solder lug termination for secure PCB attachment
• Thermoplastic housing provides insulation resistance of 5 GOhms and environmental durability

Edgeboard Connectors Applications

• Industrial control system interconnects
• Telecommunications equipment backplanes
• Test and measurement instrument modules

Edgeboard Connectors Procurement Notes

Verify the specific suffix '203' to confirm the solder lug termination style, as other variants in the 305 series may utilize different end-treatments such as pins or tails. Ensure the target application requires the standard 0.062-inch board thickness compatibility specified for this model. Confirm RoHS3 compliance requirements align with project specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, vertically mounted connector is required for 16-position interfaces. The 0.156-inch pitch accommodates standard industrial board layouts. Verify that the 5 A current rating per contact meets the circuit load requirements. Consider the panel mount flange dimensions if space constraints exist within the enclosure design.

Edgeboard Connectors Part Context

This part belongs to the EDAC 305 Series, a line of standard card edge connectors. The series offers various position counts and termination styles to support diverse electronic assembly needs. The 305-016 variant specifically addresses applications requiring a compact 16-contact interface with robust mechanical stability.

Edgeboard Connectors Replacement Considerations

Cross-reference with EDAC 305-016-521-202 or 305-016-521-501 only if the termination style change from solder lug to pin or tail is acceptable for the PCB layout.
