Procurement Notes
Verify the specific part number against official manufacturer documentation to confirm contact count and package type. Ensure compatibility with automated surface mount assembly processes. Cross-reference technical specifications such as current rating and operating temperature with system requirements before integration.
Selection Notes
Select this component for applications requiring high-density surface mount headers. Verify that the PCB footprint matches the specified dimensions. Consider the gold plating for environments requiring long-term reliability. Confirm that the two-row layout fits within the available board space constraints.
Part Context
This component belongs to the A-BL254 series, which focuses on IC sockets and IDC connectors for flat cable applications. ASSMANN WSW specializes in developing high-quality components for data lines and front-panel interfaces. The series is designed to support reliable connections in compact electronic designs.
Replacement Considerations
Compatible substitutes include models with identical pitch and contact counts, such as A-BL-254DA36-085GSR1 or A-BL-254DA38-085GSR1, provided they match the required pin configuration and mounting style.
