Overview
The A-BL-254DA44-085GSR1 is a surface mount header connector from the Assmann WSW A-BL254 series. It features a 2.54 mm (0.100 inch) pitch with right-angle orientation for PCB integration. The component utilizes gold-plated contacts to ensure reliable signal transmission and corrosion resistance. Designed for high-density applications, it supports robust electrical performance within industrial electronic environments.
Feature Summary
- Right-angle surface mount design facilitates compact PCB layout
- Gold-plated contacts provide durable connection integrity
- Standard 2.54 mm pitch ensures compatibility with industry headers
Applications
- Industrial control systems requiring surface mount connectivity
- Consumer electronics with space-constrained circuit boards
- Communication equipment utilizing standard pin headers
Procurement Notes
Verify the specific suffix 'SR1' against manufacturer documentation to confirm reel packaging and quantity specifications. Ensure the right-angle surface mount configuration matches the target PCB footprint requirements before ordering. Cross-reference the full part number with official distributor catalogs to validate current availability and lead times.
Selection Notes
Select this component when a right-angle surface mount solution is required for 2.54 mm pitch applications. The gold plating offers superior conductivity compared to tin variants in corrosive environments. Consider the surface mount profile for automated assembly processes and reduced board height constraints.
Part Context
This connector belongs to the A-BL254 series, which provides standardized interconnect solutions for various electronic assemblies. The series includes through-hole and surface mount options with consistent 2.54 mm spacing. Assmann WSW designs these components to meet rigorous industrial standards for reliability and mechanical stability.
Replacement Considerations
Compatible substitutes must match the 2.54 mm pitch, right-angle surface mount form factor, and gold contact finish. Verify that alternative manufacturers offer identical pin counts and housing dimensions to ensure mechanical interchangeability without redesigning the PCB footprint.
