ECM43DTAD-S189

Edgeboard Connectors Overview

The ECM43DTAD-S189 is a dual female edgeboard connector manufactured by Sullins Connector Solutions. It features 86 positions arranged in two rows of 43 contacts with a 0.156-inch (3.96mm) spacing. The connector utilizes phosphor bronze contacts with a gold plating thickness of 10.0µin (0.25µm). Designed for through-hole, right-angle installation, it accommodates a card thickness of 0.062 inches (1.57mm). The insulating material is polybutylene terephthalate (PBT), and the operating temperature range spans from -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-sided female contact configuration for high-density signal routing
• Right-angle through-hole termination for secure board mounting
• Gold-plated phosphor bronze contacts ensuring reliable conductivity

Edgeboard Connectors Applications

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

Edgeboard Connectors Procurement Notes

Verify that the specific ordering suffix matches the required contact count and spacing specifications. Confirm compliance with RoHS3 standards if environmental regulations apply to the assembly. Ensure the PCB footprint aligns with the specified 0.156-inch pitch and right-angle orientation. Cross-reference the insulation material PBT against thermal requirements for the intended application environment.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female interface with 3.96mm pitch is required. Consider the 0.062-inch card thickness constraint during mechanical design. Evaluate the -65°C to 125°C temperature rating against operational extremes. Compare the phosphor bronze contact material properties against alternative alloys if higher strength or different conductivity is necessary.

Edgeboard Connectors Part Context

This part belongs to the Sullins Connector Solutions edgeboard connector family. It shares design characteristics with similar models like ECC43DCAD-S189 but differs in pitch and contact type. The product line focuses on robust interconnect solutions for demanding electronic environments. Compatibility with standard edge cards is maintained through precise dimensional tolerances.

Edgeboard Connectors Replacement Considerations

ECM43DTAD-S189-ND serves as the DigiKey equivalent identifier. Verify mechanical dimensions and electrical ratings before substituting with generic equivalents. Ensure any replacement maintains the 0.156-inch pitch and dual-row configuration.
