Overview
The A-BL-254DA42-085GSR1 is a female header connector from the ASSMANN WSW A-BL254 series. It features 42 positions with a 2.54 mm (0.100 inch) pitch. The component utilizes surface mount technology in a right-angle configuration. Contacts are gold-plated bronze, rated for 12A current and 500V voltage. The operating temperature range spans from -40°C to 105°C, and the housing meets UL 94 V-0 flammability standards.
Feature Summary
- Right-angle surface mount design for compact PCB integration
- Gold-plated contacts ensure reliable signal transmission
- High current and voltage rating for robust performance
Applications
- Industrial control systems
- Consumer electronics assemblies
- Communication equipment interfaces
Procurement Notes
Verify the complete part number including the suffix GSR1 to confirm tape and reel packaging specifications. Ensure compatibility with automated pick-and-place equipment due to the surface mount format. Cross-reference the manufacturer datasheet for precise reflow soldering profile requirements to maintain connection integrity during assembly processes.
Selection Notes
Select this model when a right-angle female header is required for space-constrained designs. The 42-position count suits applications needing moderate I/O density. Verify that the PCB footprint matches the surface mount land pattern. Consider the 2.54mm pitch standard for mating with compatible male headers or flat ribbon cables.
Part Context
This component belongs to the A-BL254 series of connectors designed by ASSMANN WSW. The series specializes in IDC and IC socket solutions. This specific variant focuses on surface mount female headers, providing a standardized interface solution for modern electronic manufacturing needs within the broader connector portfolio.
Replacement Considerations
Compatible substitutes include other 42-position, 2.54mm pitch, right-angle female headers from ASSMANN WSW such as the A-BL-254DA46-085GSR1 or A-BL-254DA36-085GSR1, provided the position count aligns with the design requirements.
