Overview
The A-BL-254DA78-085GSR1 is a 78-position female header manufactured by Assmann WSW Components. It features a 2.54 mm (0.100 inch) pitch and utilizes a surface mount, right-angle configuration for PCB integration. The connector employs stamped pin technology with gold plating to ensure reliable electrical contact. Designed for high-density applications, this component supports secure mating with corresponding male headers in electronic assemblies requiring robust interconnect solutions.
Feature Summary
- Right-angle surface mount design for space-efficient PCB layout
- Gold-plated stamped pins for durable electrical connectivity
- 78-position capacity with standard 2.54 mm spacing
Applications
- High-density electronic circuit board assemblies
- Industrial control system interconnections
- Consumer electronics internal module linking
Procurement Notes
Verify the specific ordering suffixes and tape-and-reel packaging details directly with the manufacturer or authorized distributors. Confirm that the right-angle orientation and 78-pin count match the target PCB footprint requirements before finalizing procurement orders to ensure mechanical compatibility.
Selection Notes
Select this component when a high-count, right-angle female header is required for surface mounting. Ensure the mating male connector matches the 2.54 mm pitch and 78-position specification. Consider the right-angle profile for vertical clearance constraints within the device enclosure during the mechanical design phase.
Part Context
This part belongs to the rectangular connector family from Assmann WSW Components, specifically designed for stamping and forming processes. It serves as a critical interconnect element within the broader category of board-to-board connectors, providing standardized interface points for complex electronic systems.
Replacement Considerations
Direct substitutes must maintain the 78-position count, 2.54 mm pitch, right-angle surface mount style, and female header gender. Verify that alternative manufacturers offer identical gold plating specifications and compatible PCB footprint dimensions to ensure seamless integration without redesign.
