RCM31DCBI

Edgeboard Connectors Overview

The RCM31DCBI is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 62 positions arranged in two rows of 31 contacts with a 0.156-inch (3.96mm) pitch. The connector utilizes phosphor bronze clip spring contacts with a 10.0µin gold plating thickness for reliable signal transmission. Designed for through-hole, right-angle mounting, it accommodates a 0.062-inch board thickness and operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with clip spring contact type for secure board retention
• Through-hole right-angle termination compatible with standard PCB assembly processes
• Gold-plated phosphor bronze contacts ensure corrosion resistance and stable conductivity

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge-mounted interconnects
• Telecommunications equipment utilizing dual-edge card architectures
• Test and measurement instruments needing high-reliability signal paths

Edgeboard Connectors Procurement Notes

Verify the specific suffix requirements against the official datasheet to ensure correct contact plating thickness and insulation material compatibility. Confirm that the target application supports the specified 0.156-inch pitch and 0.062-inch card thickness constraints before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.156-inch pitch is required for through-hole mounting. Ensure the design accommodates the right-angle orientation and verify that the operating environment falls within the -65°C to 125°C temperature range specified for the PPS insulation material.

Edgeboard Connectors Part Context

This part belongs to the RCM series of card edge connectors from Sullins Connector Solutions. The series offers various pitch options and termination styles, with the RCM31DCBI specifically providing a 0.156-inch pitch configuration for dual-edge applications using phosphor bronze contacts and gold plating.

Edgeboard Connectors Replacement Considerations

Direct substitutes include ECM31DTBI and RBM31DCCN, which share similar form factors but differ in pitch or contact specifications. Verify exact dimensional and electrical compatibility before substitution.
