B5741-226-F-N-2

Overview

The B5741-226-F-N-2 is a Datamate L-Tek board-to-board receptacle connector manufactured by Harwin Inc. It features a double-row female configuration with 26 contacts arranged in a 13+13 pin layout. The connector utilizes beryllium copper contacts finished with gold plating to ensure reliable electrical performance. Designed for through-hole mounting, it adheres to a 0.079-inch (2.00mm) row spacing standard. This component is specifically engineered for vertical tail solder applications, providing secure mechanical and electrical connections between printed circuit boards.

Feature Summary

• Double-row female receptacle design for board-to-board interconnection
• Gold-plated beryllium copper contacts for signal integrity
• Through-hole vertical tail solder mounting style
• 2.00mm row spacing compatibility within the Datamate L-Tek series

Applications

• Vertical board-to-board stacking assemblies
• High-density electronic module interconnections
• Industrial control system PCB linking
• Telecommunications equipment internal wiring

Procurement Notes

This specific part number is officially classified as obsolete and is no longer manufactured by Harwin Inc. Procurement efforts should focus on identifying authorized substitute components rather than sourcing new original units. Verify that any replacement matches the required contact count, row spacing, and mounting style to ensure functional equivalence in existing designs.

Selection Notes

Engineers selecting this component must prioritize direct substitutes due to its discontinued status. The M80-8502645 is identified as a direct available substitute within the same product family. Selection criteria should strictly verify that the replacement maintains the 26-position female configuration and through-hole vertical tail solder characteristics to preserve mechanical fit and electrical interface specifications.

Part Context

The B5741-226-F-N-2 belongs to the Datamate L-Tek series of connectors from Harwin Inc., which are widely used in compact electronic systems. This series is characterized by its small form factor and high reliability. As an obsolete item, this specific variant represents a legacy solution for 26-contact double-row applications, now superseded by newer manufacturing lines or alternative part numbers within the broader Datamate ecosystem.

Replacement Considerations

The M80-8502645 is confirmed as a direct substitute for the B5741-226-F-N-2. Engineers should validate that the substitute maintains identical physical dimensions and contact arrangement before implementation.
