EBA40DCAD

Edgeboard Connectors Overview

The EBA40DCAD is a dual-row card edge connector manufactured by Sullins Connector Solutions. It features 80 total positions arranged in two rows of 40, with a 0.125-inch (3.18mm) pitch. The connector utilizes phosphor bronze contacts with 10.0µin (0.25µm) gold plating and full bellows contact types. Designed for through-hole right-angle mounting, it accommodates a board thickness of 0.062 inches (1.57mm). The insulating material is polybutylene terephthalate (PBT), supporting an operating temperature range of -65°C to 125°C.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with full bellows contacts for reliable signal transmission
• Right-angle through-hole termination compatible with standard PCB assembly processes
• Gold-plated phosphor bronze contacts ensure corrosion resistance and low contact resistance
• Polybutylene terephthalate insulation provides thermal stability within specified operating ranges

Edgeboard Connectors Applications

• Industrial control system interface connections
• Telecommunications equipment backplane interconnects
• Computing hardware peripheral module attachment
• Test and measurement instrument signal routing

Edgeboard Connectors Procurement Notes

Verify the specific ordering suffix matches the required flange characteristics and contact finish thickness. Confirm that the component complies with RoHS3 regulations if environmental standards are mandatory for the assembly. Ensure the package quantity aligns with production requirements, as distribution packaging may vary based on order volume. Cross-reference the manufacturer datasheet for precise handling instructions regarding moisture sensitivity level classification before soldering.

Edgeboard Connectors Selection Notes

Select this component when a dual-row, right-angle connection is required for non-specified card edges. The 0.125-inch pitch dictates the trace spacing on the mating board. Verify that the target PCB thickness is exactly 0.062 inches to ensure proper mechanical engagement. Consider the full bellows contact type for applications requiring robust insertion force and durability during repeated mating cycles compared to standard hairpin designs.

Edgeboard Connectors Part Context

This part belongs to the EBA series of edgeboard connectors from Sullins Connector Solutions. The series is characterized by its use of PBT insulation and specific flange options for panel or chassis mounting. The EBA40DCAD variant specifically denotes the dual-row configuration with 0.125-inch pitch, distinguishing it from single-row or different pitch alternatives within the broader product family.

Edgeboard Connectors Replacement Considerations

The RCM40DCAD offers a similar 80-position dual-row configuration but utilizes a 0.156-inch pitch and PPS insulation, requiring PCB layout adjustments. The ECA40DCSS shares the 0.125-inch pitch and PBT material but employs hairpin-style contacts instead of full bellows, which may alter insertion force characteristics.
