ECA35DCWT

Edgeboard Connectors Overview

The ECA35DCWT is a dual female edgeboard connector manufactured by Sullins Connector Solutions. It features 70 positions arranged in two rows of 35 contacts each, with a 0.125-inch (3.18mm) spacing. Designed for through-hole termination, the connector utilizes phosphor bronze contacts with a 30.0µin gold plating thickness. It accommodates a card thickness of 0.062 inches and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual row configuration providing 70 total contact positions for high-density interconnection.
• Through-hole mounting style ensures secure mechanical attachment to the circuit board.
• Gold-plated phosphor bronze contacts offer reliable conductivity and corrosion resistance.

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge connections
• Telecommunications equipment interface modules
• Test and measurement instrumentation backplanes

Edgeboard Connectors Procurement Notes

Verify the specific suffix designation against the manufacturer's current documentation to confirm exact flange characteristics and orientation. Ensure compatibility with the target PCB stack-up and mating card thickness specifications before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a 0.125-inch pitch dual-edge connector is required for through-hole assembly. Confirm that the 0.062-inch card thickness specification aligns with the system design requirements and that the operating temperature range meets environmental conditions.

Edgeboard Connectors Part Context

This part belongs to the ECC/ECA series of edge connectors from Sullins Connector Solutions. These connectors are designed for general-purpose applications where reliable signal transmission between an edge card and a motherboard is necessary. The series offers various mounting options and contact configurations.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other Sullins models within the ECA series sharing the same 0.125-inch pitch and 70-position count, provided the flange and mounting orientation match the existing design constraints.
