Overview
The A-BL200-DA-Z78D is a 78-position female header receptacle connector manufactured by Assmann WSW Components. It features a 2.00mm (0.079 inch) pitch and utilizes through-hole mounting with a right-angle configuration. The contact surfaces are finished with tin plating to ensure reliable electrical conductivity and corrosion resistance. This component is designed for secure board-to-board or cable-to-board interconnections in electronic assemblies requiring high-density connections.
Feature Summary
- Right-angle through-hole mounting design for space-efficient PCB integration
- Tin-plated contacts providing durable conductive interfaces
- High-density 78-position layout with precise 2.00mm spacing
Applications
- Industrial control system interconnects
- Consumer electronics internal wiring
- Communication equipment signal routing
Procurement Notes
Verify the specific suffix Z78D confirms tin plating rather than gold, as finish variants exist within this series. Confirm the 78-position count matches the target circuit density requirements. Ensure the right-angle orientation aligns with the mechanical enclosure constraints. Cross-reference the datasheet for mating force specifications and operating temperature ranges before finalizing the bill of materials.
Selection Notes
Select this model when a high-pin-count, low-profile connection is required on a vertical PCB edge. The right-angle form factor facilitates compact stacking or side-access cabling. Tin plating offers a cost-effective solution for general-purpose applications where frequent mating cycles are not anticipated. Compare against gold-plated alternatives if higher corrosion resistance or lower contact resistance is critical for the specific environment.
Part Context
This part belongs to the BL200 series of IDC connectors from Assmann WSW, which specializes in flat cable applications. The series provides standardized solutions for connecting ribbon cables to printed circuit boards. The DA designation typically indicates a dual-row or specific housing configuration, while the Z78D specifies the pin count and plating finish within this product family.
Replacement Considerations
Direct substitutes must match the 2.00mm pitch, 78 positions, and right-angle through-hole footprint. Verify that alternative manufacturers offer identical tin-plated contacts if oxidation resistance is required. Check mechanical dimensions for housing height and lock engagement compatibility. Generic equivalents may lack the specific locking mechanism details found in the original Assmann documentation.
