Overview
The A-BL-254DA48-085GSR1 is a female header connector from the ASSMANN WSW A-BL254 series. It features 48 contacts arranged in two rows with a 2.54 mm pitch. The component utilizes stamped pin technology and gold-plated bronze contacts for reliable signal transmission. Designed for surface-mount installation, it supports a maximum voltage of 500V and operates within a temperature range of -40°C to 105°C. The unit is supplied in tape and reel packaging, containing 1500 pieces per package.
Feature Summary
- Surface-mount right-angle female header configuration
- Gold-plated stamped pin contacts for durability
- High dielectric voltage rating of 500V
Applications
- Industrial control system interconnections
- Consumer electronics board-to-board connections
- Telecommunications equipment interfaces
Procurement Notes
Verify that the specific ordering suffix matches the required contact count and orientation. Confirm the surface-mount footprint dimensions against the PCB layout. Ensure the tape and reel specifications align with automated assembly equipment capabilities. Cross-reference the UL certification status if flame retardancy is a critical design requirement.
Selection Notes
Select this model when a high-density right-angle connection is required for space-constrained designs. The 2.54 mm pitch ensures compatibility with standard male headers. Consider the surface-mount profile for low-height applications. Verify thermal resistance during soldering processes to maintain contact integrity.
Part Context
This component belongs to the A-BL254 family of connectors, which are engineered for flat cable and general-purpose electronic applications. Assmann WSW specializes in IC sockets and IDC connectors, providing standardized solutions for various industries. This specific part represents a high-pin-count variant optimized for surface-mount technology.
Replacement Considerations
Direct substitutes include other 48-pin 2-row female headers with identical 2.54 mm pitch and surface-mount footprints. Verify mechanical compatibility before swapping manufacturers. Alternative options may exist within the same series with different mounting orientations.
