RCA43DTKI-S288

Edgeboard Connectors Overview

The RCA43DTKI-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 86 positions with a 0.125-inch (3.18mm) pitch, accommodating a standard 0.062-inch thick PCB. The contacts are made of phosphor bronze with a gold plating thickness of 30.0µin (0.76µm). Designed for through-hole termination, it supports a mounting style that includes flange features such as top opening and 4-40 threaded inserts. The insulator material is polybutylene terephthalate (PBT), ensuring stability within an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row configuration providing 86 contact positions for high-density board-edge interconnection
• Gold-plated phosphor bronze contacts ensure reliable signal transmission and corrosion resistance
• Integrated flange design with top opening and threaded inserts facilitates secure panel mounting
• Polybutylene terephthalate (PBT) insulation offers thermal stability and mechanical strength

Edgeboard Connectors Applications

• Industrial control systems requiring robust board-to-board connectivity
• Telecommunications equipment utilizing standard thickness PC boards
• Test and measurement instrumentation needing stable signal paths
• Consumer electronics assemblies with specific form factor constraints

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required contact finish and insulator material variant. Confirm that the target PCB thickness aligns with the 0.062-inch specification to ensure proper engagement. Check for any regional compliance requirements such as RoHS or REACH status relevant to the destination market. Ensure storage conditions maintain component integrity prior to assembly.

Edgeboard Connectors Selection Notes

Select this connector when a 0.125-inch pitch is required for dual-row applications. Consider the PBT insulator material for environments demanding higher thermal resistance compared to standard nylon variants. Evaluate the need for flange-mounted installation versus surface mount alternatives based on mechanical stress requirements. Verify compatibility with existing tooling for 4-40 threaded fasteners if panel mounting is planned.

Edgeboard Connectors Part Context

This component belongs to the RCA series of card edge connectors from Sullins Connector Solutions. The series is characterized by its use of phosphor bronze contacts and various insulator options including PBT and PPS. The RCA43DTKI-S288 specifically denotes the 86-position variant with a 0.125-inch pitch, distinguishing it from lower-pitch counterparts in the same product family.

Edgeboard Connectors Replacement Considerations

Direct substitutes must match the 0.125-inch pitch, 86-position count, and dual-row layout. Verify that alternative manufacturers offer compatible flange dimensions and 4-40 thread specifications. Ensure the replacement part maintains the same contact material and plating thickness for electrical equivalence.
