ABB25DYFN

Overview

The ABB25DYFN is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts each, with a 0.050-inch (1.27mm) pitch. The connector utilizes gold-plated beryllium copper cantilever contacts and a black polyphenylene sulfide (PPS) insulator. Designed for surface-mount installation via solder termination, it accommodates a 0.062-inch board thickness and operates within a temperature range of -65°C to 150°C.

Feature Summary

• Dual-edge female configuration with cantilever contact design for reliable signal transmission
• Surface-mount installation capability with solder termination for automated assembly
• Gold-plated beryllium copper contacts ensure durability and low contact resistance
• Black PPS insulation provides thermal stability and mechanical strength

Applications

• High-density circuit board interconnections
• Industrial control system modules
• Telecommunications equipment backplanes
• Consumer electronics internal interfaces

Procurement Notes

Verify the specific suffix DYFN against official Sullins documentation to confirm surface-mount orientation and flange characteristics. Ensure compatibility with standard reflow soldering profiles and check RoHS3 compliance status prior to integration into production lines.

Selection Notes

Select this model when a dual-edge female interface with a 0.050-inch pitch is required for surface-mount applications. Confirm that the target PCB supports the specified 0.062-inch thickness and that the operating environment remains within the -65°C to 150°C range for optimal performance.

Part Context

This component belongs to the ABB series of high-density card edge connectors from Sullins Connector Solutions. The series offers various configurations tailored for different mounting styles and contact densities, providing standardized solutions for complex electronic assemblies requiring robust connectivity.

Replacement Considerations

Cross-reference with other ABB series variants such as ABB25DHLT or ABB25DHFT if alternative mounting types are needed. Verify pin count, pitch, and termination method before substituting to ensure mechanical and electrical compatibility.
