BL 17 SMD 20

Headers, Receptacles, Female Sockets Overview

The BL 17 SMD 20 is a surface-mount board-to-board header connector manufactured by Fischer Elektronik. It features a single row of twenty contacts with a standard 2.54 mm (0.100 inch) pitch. The component is designed for right-angle mounting on printed circuit boards, facilitating vertical interconnection between stacked boards. The contact system accommodates pin diameters ranging from 0.635 mm to 0.85 mm, ensuring reliable mechanical engagement. Gold plating is applied to the contact surfaces to maintain signal integrity and corrosion resistance in electronic assemblies.

Headers, Receptacles, Female Sockets Feature Summary

• Surface-mount design for automated PCB assembly
• Right-angle configuration for vertical board stacking
• Single-row layout with twenty positions
• Gold-plated contacts for durable connectivity

Headers, Receptacles, Female Sockets Applications

• Board-to-board interconnects in compact electronics
• Vertical stacking of daughterboards or modules
• Industrial control systems requiring reliable surface-mount headers

Headers, Receptacles, Female Sockets Procurement Notes

Verify that the specific part number matches the required contact count and orientation. Confirm that the surface-mount footprint aligns with the target PCB design. Ensure compatibility with automated pick-and-place equipment if high-volume production is planned. Check for any specific handling requirements during storage and assembly.

Headers, Receptacles, Female Sockets Selection Notes

Select this component when a single-row, right-angle surface-mount header is required for board-to-board connections. Consider the 2.54 mm pitch and twenty-position capacity against available space. Verify that the gold-plated contacts meet the environmental and electrical requirements of the application. Ensure the housing material and thermal characteristics suit the operating conditions.

Headers, Receptacles, Female Sockets Part Context

This connector belongs to Fischer Elektronik's BL 17 SMD series, which offers various contact counts and configurations. The series provides standardized solutions for surface-mount applications, allowing designers to mix and match different lengths within the same product family while maintaining consistent mechanical and electrical interfaces across the range.

Headers, Receptacles, Female Sockets Replacement Considerations

Direct substitutes include other Fischer Elektronik BL 17 SMD variants with different contact counts, such as BL 17 SMD 18 SM, provided the pitch and mounting style remain compatible. Cross-brand replacements require matching the 2.54 mm pitch, right-angle orientation, and surface-mount footprint to ensure proper fit and function.
