BL 9 21 is listed in the Headers, Receptacles, Female Sockets range at ChipApex. The manufacturer field lists Fischer Elektronik. Its product description is for 0.635 mm and up to 0.85 mm. Review the specifications below when checking this part for your BOM.
The Fischer Elektronik BL 9 21 is a 21-position header connector designed for wire-to-board applications. It features a 2.54 mm (0.100 inch) pitch and utilizes aligned Wire-Wrap contact pins to ensure reliable electrical connections. The connector body is constructed from insulating material rated for 1500 V, providing necessary dielectric strength for electronic assemblies. This component supports wire diameters ranging from 0.635 mm to 0.85 mm, accommodating standard wire gauges commonly used in industrial and consumer electronics manufacturing.
Verify the specific pin configuration and orientation requirements against your PCB layout before ordering. Confirm that the target wire gauge falls within the specified 0.635 mm to 0.85 mm range to ensure proper crimping or wrapping performance. Check for any specific mounting hardware requirements if the connector requires additional mechanical support during installation.
Select this connector when a 21-position header is required for direct wire attachment rather than board-to-board stacking. Ensure the operating voltage does not exceed the 1500 V insulation rating of the body. Consider the physical space constraints on the PCB, as the 2.54 mm pitch dictates the hole spacing and overall footprint dimensions relative to adjacent components.
The BL 9 series represents Fischer Elektronik's line of female header connectors designed for robust wire termination. These components are part of a broader family offering various position counts, all sharing the same 2.54 mm pitch and Wire-Wrap contact technology. The series is engineered for high reliability in environments requiring stable electrical connections without soldering the wires directly to the board.
Direct substitutes must match the 21-position count, 2.54 mm pitch, and Wire-Wrap contact style. Generic headers may differ in insulation voltage ratings or wire diameter compatibility. Verify that alternative suppliers offer the same 1500 V insulation specification and compatible contact pin alignment to maintain assembly integrity.
