RCA43DRMH

Edgeboard Connectors Overview

The RCA43DRMH is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 86 positions arranged in two rows of 43, with a contact pitch of 0.125 inches (3.18 mm). Designed for through-hole mounting, it utilizes wire wrap termination and phosphor bronze contacts plated with 30.0 µin (0.76 µm) of gold. The insulator is made of polyphenylene sulfide (PPS), and the unit accommodates a PCB thickness of 0.062 inches (1.57 mm). It operates within a temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-edge female configuration with ring bellows contact type for secure mating
• Wire wrap termination method ensures reliable electrical connection
• Polyphenylene sulfide (PPS) insulator material provides thermal stability
• Gold-plated phosphor bronze contacts offer corrosion resistance

Edgeboard Connectors Applications

• Industrial control systems requiring robust interconnects

Edgeboard Connectors Procurement Notes

Verify that the specific order matches the RCA43DRMH part number exactly, as suffixes may indicate variations in packaging or lead times not detailed in standard specifications. Confirm compliance with RoHS3 and REACH regulations if required by your supply chain standards. Ensure the receiving facility has appropriate handling procedures for sensitive electronic components upon arrival.

Edgeboard Connectors Selection Notes

Select this component when a dual-edge female connector with a 0.125-inch pitch is required for wire wrap applications. The PPS insulator and gold plating make it suitable for environments demanding high reliability and corrosion resistance. Consider the 0.062-inch board thickness compatibility during mechanical design integration to ensure proper fit and alignment.

Edgeboard Connectors Part Context

This connector belongs to the RCA series of female card edge connectors from Sullins Connector Solutions. The series offers various pitch options and termination styles to accommodate different PCB design requirements. The RCA43DRMH specifically addresses needs for high-density connections with durable materials, fitting into broader industrial and commercial electronics ecosystems.

Edgeboard Connectors Replacement Considerations

Direct substitutes include RCA43DRMD, which shares identical electrical and mechanical parameters but differs in flange characteristics. Other compatible variants within the same family may exist; verify pin count, pitch, and termination style before substitution to maintain system integrity.
