ABB25DHFR

Overview

The Sullins Connector Solutions ABB25DHFR is a dual-edge female card edge connector designed for surface mount installation. It features 50 positions arranged in two rows of 25, with a 0.050 inch (1.27mm) pitch. The contacts are made of beryllium copper with a gold plating thickness of 10.0µin (0.25µm). The housing is black polyphenylene sulfide (PPS), rated for operation between -65°C and 150°C. It supports non-specified dual-edge cards up to 0.062 inches thick and includes board lock features.

Feature Summary

• Surface mount termination for automated PCB assembly
• Dual-edge female contact configuration for high-density connections
• Board lock feature ensures secure mechanical retention
• Gold-plated beryllium copper contacts for reliable conductivity

Applications

• High-density circuit board interconnections
• Edgeboard mounting systems
• Industrial control modules requiring surface mount connectors
• Telecommunications equipment backplanes

Procurement Notes

Verify the specific suffix 'FR' against manufacturer documentation to confirm surface mount orientation and board lock inclusion. Ensure compatibility with 0.062-inch card thickness and 0.050-inch pitch requirements. Confirm RoHS3 compliance status prior to integration into regulated assemblies.

Selection Notes

Select this model when surface mount technology is required for dual-edge card interfaces. The 0.050-inch pitch offers a balance between density and manufacturability. Verify that the target application supports the specified operating temperature range and requires the included board locking mechanism for stability.

Part Context

This component belongs to the ABB series of high-density card edge connectors from Sullins Connector Solutions. The series utilizes PPS insulation and gold-plated beryllium copper contacts. Variants within the series differ by termination type, such as through-hole or surface mount, and specific flange configurations.

Replacement Considerations

Direct substitutes include ABB25DHLT and ABB25DHFT, which share identical electrical specifications and form factors but may differ in packaging or minor mechanical attributes. Verify exact pinout and mounting hole alignment before substitution.
