ABB25DYRR

Overview

The ABB25DYRR is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions arranged in two rows of 25 contacts, with a 0.050 inch (1.27mm) pitch. The connector utilizes cantilever contact types made from beryllium copper with a gold surface finish thickness of 10.0µin (0.25µm). Designed for board edge or over-the-board installation, it supports a maximum card thickness of 0.062 inches (1.57mm). The housing is constructed from black polyphenylene sulfide (PPS), ensuring compliance with RoHS3 standards and an operating temperature range of -65°C to 150°C.

Feature Summary

• Dual-edge female configuration with cantilever spring contacts for reliable signal transmission
• Board edge and over-the-board mounting options with integrated board lock features
• Gold-plated beryllium copper contacts housed in high-temperature PPS insulation

Applications

• High-density circuit board interconnections
• Industrial control system backplanes
• Telecommunications equipment modules

Procurement Notes

Verify the specific suffix 'R' indicates tube packaging when ordering. Confirm that the required card thickness does not exceed the specified 0.062-inch limit. Ensure compatibility with standard wave soldering processes due to the through-hole termination style. Check for any project-specific environmental certifications beyond the standard RoHS3 compliance listed in the manufacturer documentation.

Selection Notes

Select this model for applications requiring a dual-sided connection interface with a 0.050-inch pitch. The cantilever contact design offers flexibility during insertion compared to hairpin styles. Consider the PPS material properties for thermal stability in high-heat environments. Verify that the board lock feature meets the mechanical retention requirements of the assembly.

Part Context

This component belongs to the ABB series of high-density card edge connectors from Sullins Connector Solutions. The series is characterized by its robust construction and versatile mounting capabilities. Variations within the series typically differ by position count, contact type, and termination style, while maintaining consistent pitch and housing materials.

Replacement Considerations

Direct substitutes include other Sullins models such as ABB25DHRR or ABB25DHRN, which share similar electrical characteristics but may differ in contact type or packaging. Cross-manufacturer replacements require careful verification of pinout, pitch, and mechanical dimensions to ensure functional equivalence.
