RSA31DTKH

Edgeboard Connectors Overview

The RSA31DTKH is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 62 positions with a 0.125-inch (3.18mm) pitch and accommodates a board thickness of 0.062 inches (1.57mm). The contacts are made of phosphor bronze with a gold plating finish, housed in a green polyphenylene sulfide (PPS) insulator. Designed for right-angle through-hole mounting, it includes flange features with top opening and no threads.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 62 contact positions for high-density interconnect applications
• Right-angle through-hole termination method ensures secure PCB mounting
• Gold-plated phosphor bronze contacts offer reliable signal transmission
• Green PPS insulator provides thermal stability and mechanical strength

Edgeboard Connectors Applications

• Industrial control systems requiring robust edge card connections
• Telecommunications equipment utilizing standard card edge interfaces
• Test and measurement devices needing reliable signal pathways

Edgeboard Connectors Procurement Notes

Verify the specific suffix requirements against the manufacturer's current datasheet to ensure compatibility with intended mounting styles and environmental conditions. Confirm that the gold plating thickness meets the application's wear resistance needs. Check RoHS compliance status if operating in regulated regions. Ensure the selected variant matches the required board thickness tolerance of 0.062 inches.

Edgeboard Connectors Selection Notes

Select this component when a right-angle, dual-row female connector is required for 0.125-inch pitch applications. Consider the green color coding for visual identification within complex assemblies. Evaluate the need for through-hole versus surface mount alternatives if space constraints differ. Verify that the PPS material properties align with the operational temperature range of -65°C to 125°C.

Edgeboard Connectors Part Context

This part belongs to the RSA31 series of card edge connectors from Sullins Connector Solutions. The series offers various configurations including different row counts, pitches, and termination styles. The RSA31DTKH specifically addresses needs for dual-row, right-angle connections with standard 0.125-inch spacing, fitting into broader industrial connector portfolios.

Edgeboard Connectors Replacement Considerations

Direct substitutes may include other RSA31 variants with identical electrical and mechanical specifications but different suffixes indicating minor manufacturing or packaging changes. Cross-reference with similar models like RSA31DTKS only if side-mounting features are acceptable instead of top-opening.
