ABB25DYRN-S1355

Overview

The ABB25DYRN-S1355 is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions per side, totaling 100 contacts, with a 0.050-inch (1.27mm) pitch. The connector utilizes cantilever contacts made of beryllium copper with a gold plating thickness of 10.0µin (0.25µm). Designed for board edge or over-mount installation, it accommodates a card thickness of 0.062 inches (1.57mm). The insulating material is polyphenylene sulfide (PPS), and the unit operates within a temperature range of -65°C to 150°C.

Feature Summary

• Dual-edge configuration with 100 total female contacts
• Cantilever contact design for reliable board insertion
• Gold-plated beryllium copper contacts for corrosion resistance
• Polyphenylene sulfide insulation for thermal stability

Applications

• High-density interconnect systems
• Industrial control boards
• Telecommunications equipment
• Computer peripheral interfaces

Procurement Notes

Verify the specific suffix requirements against your assembly drawings to ensure compatibility with mating card dimensions and mounting constraints. Confirm that the beryllium copper contact material meets the mechanical endurance specifications required for your application cycles. Ensure storage conditions align with the moisture sensitivity level classification to prevent soldering defects during reflow processes.

Selection Notes

Select this model when a dual-sided connection is required for a 0.062-inch thick PCB. The beryllium copper construction offers superior spring retention compared to phosphor bronze alternatives. Verify that the operating environment does not exceed the 150°C thermal limit defined for the PPS housing material.

Part Context

This component belongs to the ABB series of card edge connectors from Sullins Connector Solutions. The series provides various position counts and contact materials to suit different density and durability requirements. The ABB25 variant specifically addresses mid-range density applications requiring robust electrical performance.

Replacement Considerations

Direct substitutes include GBB25DYRN-S1355, which shares identical physical dimensions but uses phosphor bronze contacts instead of beryllium copper. Verify contact material suitability before substitution as mechanical properties differ.
