GSA40DTKH-S288

Edgeboard Connectors Overview

The GSA40DTKH-S288 is a dual-row female card edge connector manufactured by Sullins Connector Solutions. It features 80 positions with a 0.125-inch (3.18mm) contact center spacing and supports a maximum card thickness of 0.062 inches (1.57mm). The connector utilizes phosphor bronze contacts with a gold plating thickness of 10.0µin (0.25µm) and employs ring bellows contact types for reliable engagement. Designed for through-hole termination, the housing is constructed from polyamide (PA9T), nylon 9T, and is colored black. It operates within a temperature range of -65°C to 125°C and includes top-mounting openings with a 0.125-inch diameter.

Edgeboard Connectors Feature Summary

• Dual-row female configuration with ring bellows contact type for secure card insertion
• Gold-plated phosphor bronze contacts ensuring corrosion resistance and conductivity
• Polyamide insulation material providing thermal stability and mechanical strength
• Top-mounting flange design with specific opening dimensions for panel integration

Edgeboard Connectors Applications

• Industrial control system backplanes
• Telecommunications equipment interconnects
• Test and measurement instrument modules
• Embedded computing board connections

Edgeboard Connectors Procurement Notes

Verify the specific suffix S288 against official manufacturer documentation to confirm packaging and handling specifications. Ensure that the ordering suffix does not alter the fundamental electrical or mechanical interface unless explicitly stated in the datasheet. Cross-reference the DigiKey part number GSA40DTKH-S288-ND with the original component data to validate authenticity and current availability status before finalizing procurement orders.

Edgeboard Connectors Selection Notes

Select this connector when a dual-row female interface with 0.125-inch spacing is required for thick card applications up to 0.062 inches. The black polyamide housing and gold-plated phosphor bronze contacts offer durability in industrial environments. Consider the through-hole mounting style and top-flange design for panel installation requirements. Verify compatibility with existing PCB layouts and mating card edge dimensions to ensure proper fit and electrical performance.

Edgeboard Connectors Part Context

This component belongs to the GSA40 series of card edge connectors from Sullins Connector Solutions. It shares the basic product identifier GSA40 but differs in contact spacing, housing material, and mounting features compared to variants like RSA40DTKH or ESA40DTKH-S288. The GSA40 series generally targets high-reliability applications requiring robust mechanical retention and stable electrical connections in demanding operational conditions.

Edgeboard Connectors Replacement Considerations

Direct substitutes include GSA40DTKD and GSA40DTKD-S288, which share similar 80-position dual female configurations. Verify if the K vs D suffix indicates a difference in flange characteristics or material composition as documented in the official datasheet. Ensure any replacement maintains the 0.125-inch spacing and 0.062-inch card thickness compatibility.
