305-016-520-201

Edgeboard Connectors Overview

The EDAC 305-016-520-201 is a standard card edge connector from the 305 series, designed for dual-row board-to-board interconnections. It features 16 positions with a 3.96 mm (0.156 inch) pitch and accepts PCB thicknesses between 1.37 mm and 1.78 mm. The connector utilizes gold-plated copper alloy contacts with a 5 A current rating and supports solder lug termination. Constructed with thermoplastic insulation, it operates within a temperature range of -40°C to +105°C and complies with RoHS3 standards.

Edgeboard Connectors Feature Summary

• Accepts between-contact and in-contact polarizing keys for secure alignment
• Dual female contact configuration ensures reliable signal transmission
• Gold-plated copper alloy contacts provide corrosion resistance
• Thermoplastic housing offers mechanical stability

Edgeboard Connectors Applications

• Industrial control systems requiring polarized connections
• Telecommunications equipment interfaces
• Computing hardware backplanes
• Test and measurement instrumentation

Edgeboard Connectors Procurement Notes

Verify that the specific part number matches the required polarizing key compatibility, as the 305 series supports both between-contact and in-contact options. Confirm the thermal rating aligns with operational environments up to 105°C. Ensure the PCB thickness falls within the specified 1.37 mm to 1.78 mm range for proper insertion. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

Edgeboard Connectors Selection Notes

Select this component when a dual-row card edge connector with polarizing key capability is required. The 3.96 mm pitch suits applications needing robust spacing between contacts. Consider the 5 A continuous current rating for power distribution needs. Verify that the solder lug termination style fits the target PCB layout constraints compared to pin or surface mount alternatives.

Edgeboard Connectors Part Context

This model belongs to the EDAC 305 series, which specializes in standard card edge connectors. The series provides various position counts and mounting styles while maintaining consistent electrical characteristics. The 305-016-520-201 variant specifically addresses low-pin-count applications requiring high reliability and polarization features for critical data links.

Edgeboard Connectors Replacement Considerations

Compatible substitutes include other EDAC 305 series variants such as 305-016-520-202, which shares identical electrical and mechanical specifications but may differ in packaging or minor manufacturing details. Cross-referencing the full datasheet is necessary to confirm interchangeability regarding polarizing key acceptance.
