Overview
The A-BL-254DA76-085GSR1 is a 76-position female header connector manufactured by Assmann WSW Components. It features a 2.54 mm pitch and utilizes surface mount right-angle mounting for PCB integration. The contacts are gold-plated stamped pins designed for reliable signal transmission. This component belongs to the A-BL-254 series, providing a standardized interface solution for electronic assemblies requiring high-density connections with specific orientation constraints.
Feature Summary
- Surface mount right-angle configuration for space-efficient PCB layout
- Gold-plated stamped pin contacts ensuring durable connection integrity
- Standardized 2.54 mm pitch compatible with industry-standard mating headers
Applications
- High-density electronic circuit board interconnections
- Consumer electronics assembly requiring right-angle routing
- Industrial control modules with surface-mounted components
Procurement Notes
Verify the exact part number against manufacturer specifications to ensure compatibility with required current ratings and environmental conditions. Confirm that the surface mount footprint matches the design file. Check for RoHS compliance status if required by project regulations. Ensure storage conditions maintain contact plating quality prior to assembly.
Selection Notes
Select this component when a right-angle surface mount female header is required for 2.54 mm pitch applications. Consider the 76-position count to match system channel requirements. Evaluate mechanical stability needs for right-angle configurations versus straight headers. Verify that the gold plating meets corrosion resistance standards for the operating environment.
Part Context
This connector is part of the A-BL-254 series from Assmann WSW Components, which specializes in IC sockets and IDC connectors. The series provides standardized solutions for flat cable and PCB applications. Assmann WSW focuses on developing tailored connector systems for various industrial and consumer electronics markets.
Replacement Considerations
Direct substitutes within the same series may include other position variants such as A-BL-254DA36-085GSR1 or A-BL-254DA38-085GSR1 if fewer positions suffice. Cross-referencing with generic 2.54 mm SMD right-angle female headers requires verification of footprint dimensions and contact material specifications.
