ABB25DHRR

Overview

The ABB25DHRR is a dual-edge female card edge connector manufactured by Sullins Connector Solutions. It features 50 positions with a 0.050-inch (1.27mm) pitch across two rows of 25 contacts each. The connector utilizes clip spring contacts made from beryllium copper with a gold plating thickness of 10.0µin (0.25µm). Designed for board edge or straddle mount installation, it accommodates a card thickness of 0.062 inches (1.57mm). The housing is constructed from black polyphenylene sulfide (PPS), ensuring compliance with RoHS3 standards.

Feature Summary

• Dual-edge configuration supports simultaneous connection to both sides of the circuit board
• Clip spring contact type provides reliable mechanical retention and electrical stability
• Board lock feature secures the connector to the host PCB during operation
• Gold-plated beryllium copper contacts ensure corrosion resistance and conductivity

Applications

• High-density card edge interconnects
• Board extension applications
• Straddle mount installations requiring robust locking mechanisms

Procurement Notes

Verify that the specific suffix 'RR' corresponds to the required board lock and straddle mount configuration, as variations exist within the ABB series. Confirm compatibility with the target PCB thickness of 0.062 inches and the 0.050-inch pitch requirement. Ensure the application environment remains within the specified operating temperature range of -65°C to 150°C. Check for any specific handling requirements related to the tube packaging format provided by the manufacturer.

Selection Notes

Select this component when a dual-edge female connector with integrated board locking is required for straddle mounting. The 0.050-inch pitch and 50-position count define the density constraints. Consider the PPS insulation material for thermal stability and the gold contact finish for durability in repeated mating cycles compared to tin-plated alternatives.

Part Context

This part belongs to the ABB25 high-density card edge connector family from Sullins Connector Solutions. It shares common specifications such as pitch, position count, and contact material with other variants like ABB25DHRN and ABB25DHFT, differing primarily in mounting style and accessory features. The 'RR' suffix specifically denotes the inclusion of board locks and suitability for straddle mount applications.

Replacement Considerations

ABB25DHRN serves as a functional substitute offering identical electrical parameters but lacks the board lock feature.
